  • SQL Server 2008 Unique Problem for bring DB Online...

    - by Nai
    This is my error I am facing TITLE: Microsoft.SqlServer.Smo Set offline failed for Database 'Go3D_Retailer ------------------------------ ADDITIONAL INFORMATION: An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo) Unable to open the physical file "E:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\ftrow_Go3D_catalog.ndf". Operating system error 2: "2(failed to retrieve text for this error. Reason: 15105)". Database 'Go3D_Retailer' cannot be opened due to inaccessible files or insufficient memory or disk space. See the SQL Server errorlog for details. ALTER DATABASE statement failed. (Microsoft SQL Server, Error: 5120) Background to this error I've been trying to move my destination logshipping database to another physical server for analysis purposes. Because I do not have active directory set up, I had to hack my process by using the same username/password for both the source and destination servers to get the process to work. Following that, I used this guy's solution to move the destination database to another server. However, this error occurs when I try to bring the database back online. I don't have an E drive on my server and I have no idea why it's trying to open a file from E drive. I have over a 100gb left on my hard disk so it's definitely not a space issue. This sounds like a bug... Any ideas? I'm running SQL Server 2008 Enterprise edition on Windows Server 2008 R2 64bit

  • Remote Desktop Connection to the same screen as on the monitor?

    - by Ricket
    I'm running Windows Home Server on, well, my server. It's in my entertainment center, hooked to my TV, and I use it to listen to music and watch movies. Right now I have a keyboard and mouse stuck beside my TV so that I'm able to load a movie. It would be nice, though, to be able to remotely control the screen. Remote Desktop Connection seems to open its own session in the background, separate from the session shown on the monitor. This doesn't do any good because things started via remote desktop must be closed or changed via remote desktop, and I can't start a movie with remote desktop and then see it from the screen. Is there a way to get Remote Desktop Connection to connect to the visible screen? I am currently using UltraVNC; it was doing the job, but it has its quirks. For instance, the problem just now that prompted me to ask this question; upon trying to connect, UltraVNC informs me that "Server closed connection - The server running as application". This is just one of several problems I've had with it, and I want something that is as reliable and low-maintenance as the built-in Remote Desktop Connection. (and free) If the answer to the above is no, I'm welcome to recommendations for a different remote desktop system to try.

  • Vim: Custom Folding function done, custom highlighting required

    - by sixtyfootersdude
    I have defined a function in vim to properly indent folds. Ie so they look like this: Unfolded this is text also text indented text indented text not indented text folded with default function this is text also text +-- 2 lines: indented text ---------------------------- not indented text folded with my new function this is text also text ++- 2 lines: indented text ---------------------------- not indented text The only problem is the the highlighting is still like this: folded with my new function (highlighting shown with tag) this is text also text <hi> ++- 2 lines: indented text ----------------------------</hi> not indented text I would like the highlighting to start at the ++ and not at the beginning of the line. I have looked in the vim manual but could not find anything like that. One so-so solution I found was to make the background black. highlight Folded ctermbg=black ctermfg=white cterm=bold But this make folds less visible. I have tried several variations of: syn keyword Folded lines syn region Folded ... But I don't think that this is the way that folds are selected. Can anyone offer a suggestion? By the way this is my function to indent the folds: set foldmethod=indent function! MyFoldText() let lines = 1 + v:foldend - v:foldstart let ind = indent(v:foldstart) let spaces = '' let i = 0 while i < ind let i = i+1 let spaces = spaces . ' ' endwhile let linestxt = 'lines' if lines == 1 linestxt = 'line' endif return spaces . '+' . v:folddashes . ' '. lines . ' ' . linestxt . ': ' . getline(v:foldstaendfunction endfunction au BufWinEnter,BufRead,BufNewFile * set foldtext=MyFoldText() By the way thanks to njd for helping me get this function setup.

  • RDS, RDWeb, and RemoteApp: How to use public certificate for launching apps on session host?

    - by Bret Fisher
    Question: How do i tell RDWeb to launch apps from remote.domain.com rather then host.internaldomain.local? Environment: Existing org with AD forest. New single Server 2012 running all Remote Desktop Services roles for session host. Used the new 2012 wizard to setup "QuickSessionCollection" with roles: RD Session Host RD Connection Broker RD Gateway RD Web Access RD Licensing Everything works with self-signed cert, but we want to prevent those. The users are potentially non-domain machines so sticking a private root cert for on their machines isn't an option. Every part of the solution needs to use public cert. Added public remote.domain.com cert to all roles using Server Manager GUI: RD Connection Broker - Enable Single Sign On RD Connection Broker - Publishing RD Web Access RD Gateway So now everything works beautifully except the last step: user logs into https://remote.domain.com user clicks a app icon, which in background downloads a .rdp file that is signed by remote.domain.com. .rdp is set to use RD Gateway, which is remote.domain.com .rdp says app is hosted on internal host.internaldomain.local, which doesn't match the RDP-tcp TLS cert of remote.domain.com, and pops a warning. It's this last step that I'd like to fix. Is there a config option in PowerShell, WMI, or .config to tell RDWeb/RemoteApp to use remote.domain.com for all published apps so the TLS cert for RDP matches what the Session Host is using? NOTE: This question talks about this issue, and this answer mentions how you might fix it in 2008, but that GUI doesn't exist in 2012 for RemoteApp, and I can't find a PowerShell setting for it. NOTE: Here's a screenshot of the setting in 2008R2 that I need to change. It tells RemoteApp what to use for the Session Host server name. How can I set that in 2012?

  • Improving Performance of RDP Over LAN

    - by Jared Brown
    Architecture: A deployment of 6 new HP thin clients (Windows XP Embedded) with TCP/IP access to several new HP servers (Windows 2003 Server). Each thin client is connected over fiber optic to a Gigabit Cisco switch, which the servers are connected to. There are 10/100 Ethernet to fiber converter boxes on each end of the fiber cables. Problem: Noticeable lag over RDP while using the Unigraphics CAD package. 3D models take .5 to 1 second to respond to mouse actions. Other Details: Network throughput on each thin client's RDP session is 7288 kbps. RDP connection settings - color setting: 15k, all themes, etc. turned off. Local and remote system performance stats are well within norms (CPU, Memory, and Network). Question: Are there newer versions of terminal services or RDP I can use on my existing OSes? Are there compression algorithms, etc. that are well suited for a high-bandwidth LAN? Are there valid alternatives that will yield higher performance (i.e. UltraVNC with drivers installed)? Are there TCP/IP tuning options I can exploit?

  • TomTom GO & Ubuntu Linux: impersonating a GPRS phone with dund

    - by Broam
    Background: I've called TomTom support, and they don't support Linux. I can get my GO 730 to mount Mass Storage, and I found a shell script that will allow me to install maps (haven't tried it; will update when I do.). As of note: USB 2.0 only. 1.1 ports will not work. However--I still can't update the TomTom or take advantage of any traffic services. The GO will connect to a mobile phone, but I don't have one that supports tethering. However, I've found a site that claims to know a way to get a Linux Machine to impersonate a phone advertising GPRS services and it apparently works in Fedora as old as FC4. I'm having some serious trouble getting this to work on Ubuntu 9.10 Karmic, mainly because I think some of the built-in bluetooth stuff is getting in the way. Changing the class bits in main.conf (hcid.conf does not exist) doesn't crash..., and dund starts and listens, but the TomTom device never seems to want to connect to my machine. I haven't played around much with sdcptool (I think that's the name, not in front of a Linux machine right now) but maybe I have to advertise the DUN profile...I'm not very sure. My Question: I have no way to diagnose the problems. What are some diagnostic tools I can use to help dig down and figure out what's going on? Update: apparently dund is a legacy tool that's going away. What replaces it?

  • Unable to stop chrome.exe *32

    - by chipperyman573
    So I was installing roboform today and was unable to stop the process chrome.exe *32... Even when I uninstalled chrome. This is the error I got: I used lockhunter and it said it was located in %appdata%\Local\Google\Chrome. However, it was unable to unlock, delete or rename. When I use explorer to delete or rename that folder, it says it's being used by Chrome. Even after restarting my computer it still does this. I've tried using the built in chrome task manager (Wrench View Background Pages) and I can't seem to find a process there that has the same amount of memory. I have run many, many virus scans, by: Microsoft security essentials AVG (Free version) Malwarebytes (Pro version) Norton 360 (Pro version) McAfee (Pro Version) Avira (Free version) Avast!

  • Problem setting command-line console resolution. vbeinfo in grub2 does not report all resolutions

  • Amazon AWS EC2 + Puppet, get Puppet to know AWS instance tags

    - by Piotr Jasiulewicz
    I am having a problem with my AWS deployment, fairly new to AWS and Puppet. So coming to my question - can you distinguish puppet nodes with AWS machine tags or CNAME domains? A little background about the plan: have multiple clusters of machines, one php cluster, one legacy php cluster, one java cluster, one perl cluster control configuration with puppet - still pretty new to puppet but as a developer I like the idea of being able to version control configuration of servers have autoscaling enabled on those clusters - obviously the main benefit of the cloud that makes the much hight cost when it comes to any reasonable performance worth it (those amazon machines are slower than my phone...) deployment controlled by Capistrano, this makes things a lot easier So in AWS you get those super nasty public/private machine dns's... no way you can identify machines on those. In order to easer the problem, seams like AWS want's you to tag everything - so I did. Found a script that makes a CNAME record for each machine with the tag "ShortName" thanks to the Route53 API. Every machine has a ShortName tag that becomes its CNAME, unfortunately puppet still resolves the private dns name. I'd like to have node 'perl-cluster'{} in puppet, anyone any clue ho to achieve this? Thanks

  • Sticky sessions not sticky on coldfusion cluster

    - by GreatSeaSpider
    we're trying to deploy a legacy coldfusion site onto a new CF8 cluster. The cluster consists of three cf instances running under JRUN4 on a single windows 2008 server. I've got the cluster set to not replicate sessions, and sticky sessions turned on. each instance is set to use J2EE session variables. The application tag for the site has: sessionmanagement="Yes" setclientcookies="Yes" setdomaincookies="Yes" when each instance starts... no errors are reported in the instance log and they join the cluster without any issues. though the intances do have: 16/10 08:31:25 info SessionReplicationService successfully joined a JINI lookup service (assigned JINI-ID .....) and 16/10 08:31:25 info Clusterable service SessionReplicationService discovered a SessionReplicationService peer on a JRun server named "xxxx" on host xxxx which is interesting since session replication is definately off, is the SessionReplicationService responsible for sticky sessions aswell? thats enough background, the problem is that the sticky sessions appear to simply not work, each request is bounced to a different instance, and it seems as if the sessions are being lost on each instance anyways? As soon as the cluster is down to a single instance, the web app works exactly as expected and the sessions seem fine. has anybody got any ideas for me? i've been trawling the web and I cant seem to find any answers.

  • Can I change the user id of a user on one Linux server to match another server in /etc/passwd?

    - by user76177
    I have a Rails application that is on a virtual machine (RHEL 6) and it's database is on dedicated hardware (also RHEL 6). The app server has an NFS directory from the db server mounted and accessible. It needs to write images to that server that are uploaded via the app. Background processes on the db server need to read and write to the same directory, as they perform resizing operations on the uploaded files. Right now none of this is working, because the user ids are different between the two systems. I only need this to work for this one application, so it is way too much overhead to put an LDAP system in place. Can I simply change the user id of this one user in one of the systems, or will that cause mass chaos? UPDATE: The fix worked, at least on local devices. Unfortunately the device I have mounted to the main db server still thinks my user id is 502 instead of 506. Do I need to remount that device, or is there an NFS daemon I can stop and restart to refresh it?

  • Mystery undeletable file

    - by Hugh Allen
    I can't delete C:\Config.Msi\75ce84f.rbf. it's not readonly, system or hidden it's not in use by another process (according to Process Explorer) the NT security permissions aren't the problem either - I am the owner and have Full Control ; as a double-check, the Effective Permissions tab shows that I have permission to delete. Yet trying to delete the file gives "Access is Denied" from both Explorer and cmd. I can however rename it or move it to another folder on the same drive. I can also read it and Virustotal says it's clean which is what I would expect (it's just a Windows Installer temp file - a copy of some DLL I think). The relevant line from Process Monitor is: 6:52:14.3726983 PM 112 Explorer.EXE SetDispositionInformationFile C:\Config.Msi\75ce84f.rbf CANNOT DELETE Delete: True Write 1232 Background: I'm using XP SP2. I recently repaired my Adobe Reader installation to make it the default browser plugin again instead of Foxit. (there seems to be no UI to do it otherwise?) So the installer did its thing and then asked to reboot. As is my habit when rebooting is inconvenient I declined the offer and ran pendmoves to find out what files the installer had scheduled to move / delete. It wanted to delete two files with .rbf extension (rollback files) located in C:\Config.msi\. (this applies to both even though I've been speaking about one). So I tried to delete them manually and couldn't. Does anyone have any ideas what could be preventing deletion? (and I don't think it's malware even though I'm not running AV at the moment)

  • SQL Server 2008 cluster freezing

    - by Ed Leighton-Dick
    We have run into a strange situation in which a SQL Server 2008 single-node cluster hangs. As background, we are rebuilding a Windows Server 2003/SQL Server 2005 two-node cluster using Windows 2008 and SQL Server 2008. Here's the timeline: Evicted the passive node (server B) from the Windows 2003/SQL 2005 cluster. The active node now functions as a single-node cluster with no problems. Wiped server B's disks and installed Windows 2008 and SQL Server 2008 as a single-node cluster. Since we do not want to the two clusters to communicate yet, we left the cluster's private network "heartbeat" adapter unconfigured. The cluster comes up and functions normally. Moved all databases to the new cluster. Cluster continues to function normally. Turned off server A (old cluster) in preparation for rebuilding as the second node of the new cluster. SQL Server instance on server B (new cluster) locks up, even though it should have no knowledge of or interaction with server A. Restarted server A. SQL Server instance on server B (new cluster) immediately begins working again. Things we have tried: The new cluster's name responds to ping and NETBIOS requests, even while the SQL Server is hung. We have confirmed that no IP address is assigned to the old heartbeat adapter, and it is not pulling an IP address from DHCP. Disabling the heartbeat's network card has the same effect. No errors were generated in any logs - Windows or SQL. When the error first occurred, it sat in the hung state for quite some time (well over 10 minutes) before anyone figured out what was going on. This would seem to eliminate any sort of normal cluster timeout in which it would have been searching for the other node (even if one had been configured). Server B is running Windows 2008 SP2, fully patched, and SQL Server 2008 SP1 CU7 (10.0.2775).

  • Any ideas out there as to how the data can be recovered from an SSD?

    - by ben
    A friend had some form of catastrophic failure on an HP mini 1000, unbootable. Of course there was data that wasn't backed up. I've removed the SSD and hooked it up to a ZIF 40 enclosure but can not seem to get the drive to be recognized in Windows 7. In Disk Management it displays as present, but uninitialized. Attempting to initialize it presents an error Virtual Disk Manager - "The device is not ready". There is scant information on MIE (the custom OS), so I'm not even sure what kind of file system I'm dealing with. In any case, if the filesystem is indeed some flavor other than FAT or NTFS, is this error consistent with that? Are there any creative ideas out there as to how the data can be recovered? Update: Thanks for all the suggestions! I hadn't even considered running a live cd. Unfortunately no luck with Ubuntu (live cd) or explore2fs. The zif connection seems ok (color coded green led for proper connect, orange for not). The drive can't be initialized and therefore can't be formatted, so I guess there may be some real damage. Probably needs to head to a specialist. Thanks again for the feedback, much appreciated.

  • Starfield Wildcard SSL Certificate Not Trusted in All Browsers

    - by Austen Cameron
    I am at a loss as to what else I might try in order to debug this issue with a Starfield Wildcard SSL Certificate. The problem is that in certain browsers (Safari or the most-updated chrome you can get for OS X 10.5.8 for example) the certificate comes up as untrusted, even on the root domain. My server setup / background info: General LAMP setup - CentOS 6.3 - on a Godaddy VPS Starfield Technologies Wildcard SSL certificate Installed using the instructions from godaddy's support pages ssl.conf lines are basically as follows: SSLCertificateFile /path/to/cert/mysite.com.cert SSLCertificateKeyFile /path/to/cert/mysite.key SSLCertificateChainFile /path/to/cert/sf_bundle.crt Everything seemingly worked fine until the other night when I noticed the problem in OS X, I assume it's more browser version related, but have only been able to replicate it on that particular machine. What I have tried: Updating sf_bundle.crt from godaddy's cert repository and Starfield's repository versions Following This ServerFault answer from Jim Phares - changing the ChainFile line to sf_intermediate.crt from Starfield's repository Using http://www.sslshopper.com/ssl-checker.html on my url It says the domain is correctly listed on the certificate but comes up with an error that reads The certificate is not trusted in all web browsers. You may need to install an Intermediate/chain certificate to link it to a trusted root certificate. What might I try next to remedy the untrusted certificate issue? Let me know if there is any other information needed that might help debugging this issue. Thanks in advance!

  • Google Chrome mouse wheel takes keyboard focus

    - by Steve Crane
    I recently switched the default browser on all my machines from Firefox to Google Chrome. In general I’m loving Chrome but there is one behaviour that is driving me nuts. Scrolling with the mouse wheel takes keyboard focus away from the document. Here’s what happens. I’ve just opened a page or switched to a new tab and the page has keyboard focus as I can use the keyboard up/down and PgUp/PgDn keys to scroll it; no problem there. But if I then use the wheel on my mouse to scroll the page, it loses the keyboard focus and no longer responds to up/down, PgUp/PgDn, or in fact any other keyboard keys. I have to click on the page background to restore the keyboard focus. This is a minor inconvenience for scrolling but where it really drives me nuts is in Google Reader and Gmail where I use keyboard shortcuts a lot. Here I find that I scroll the article or e-mail I’m reading with the mouse wheel then get no response when I press j/k to move to the next or previous article or e-mail. I am using Windows 7 and the Chrome dev channel (version 4.0.249.43).

  • Create new folder for new sender name and move message into new folder

    - by Dave Jarvis
    Background I'd like to have Outlook 2010 automatically move e-mails into folders designated by the person's name. For example: Click Rules Click Manage Rules & Alerts Click New Rule Select "Move messages from someone to a folder" Click Next The following dialog is shown: Problem The next part usually looks as follows: Click people or public group Select the desired person Click specified Select the desired folder Question How would you automate those problematic manual tasks? Here's the logic for the new rule I'd like to create: Receive a new message. Extract the name of the sender. If it does not exist, create a new folder under Inbox Move the new message into the folder assigned to that person's name I think this will require a VBA macro.

  • Using VLANs/subnetting to separate management from services?

    - by YouAreTheHat
    Background: I recently purchased a server and a managed switch for my home in the hopes of getting more experience and some fun toys to play with. The devices and appliances I either have or plan to have cover a broad spectrum: router, DD-WRT AP, Dell switch, OpenLDAP server, FreeRADIUS server, OpenVPN gateway, home PCs, gaming consoles, etc. I intend to segment my network with VLANs and associated subnets (e.g., VID10 is populated by devices on 192.168.10.0/24). The idea is to secure the more sensitive appliances by forcing traffic through my router/FW. Setup: After thinking and planning for some time, I have tentatively decided on 4 VLANs: one for the WAN connection, one for servers, one for home/personal devices, and one for management. In theory, the home VLAN will have limited access to the servers, and the management VLAN will be totally isolated for security. Question: Since I want to restrict access to management interfaces, but some appliances have to be accessible to other devices, is it possible/wise to have only management (SSH, HTTP, RDP) available on one VLAN/IP and only services (LDAP, DHCP, RADIUS, VPN) available on other? Is this a thing that is done? Does it gain me the security I think it does, or hurt me in some way?

  • ClearType setting ignored in Windows Virtual PC with Windows XP Pro

    - by Yadyn
    I have a VM set up through Windows Virtual PC for Windows XP Pro and I have been completely unable to get ClearType to work. I have turned it on in the Display - Appearance - Effects dialog but it seems like it completely ignores this. All text is still without any anti-aliasing. Even setting it to normal smoothing doesn't work. If I disable Integration Features, it seems to work, but then I lose a lot of nice features. What's weirder, is that the Windows XP Mode installed with Windows Virtual PC (this is separate from my XP Pro VM) works with both ClearType and Integration Features just fine. I turned it on the same way and it works like a charm, no problems. I'm running Windows 7 Professional 64-bit as the host OS and have the latest (to my knowledge) Windows Virtual PC installed. The only funny business I can think of is that I've enabled 24-bit color via the Group Policy setting inside each XP virtual machine (both Pro and the stripped down XP mode copy). This is a fairly well-known trick documented all over the web, but here's a typical post about it.

  • Troubleshooting wireless connection problem / site survey?

    - by johnnyb10
    I just started in the IT department of a small company (200 users) and it's clear that one of the main problems that is driving everyone crazy is the spotty nature of the wireless connectivity throughout the office, particularly in certain conference rooms. This is a huge problem because the connection often drops during important presentations to clients. I was hired to help ease the load on the existing IT admin, who has done a great job, but is overloaded with many other tasks to deal with. So I would like to try to help out with this wireless issue. I am looking for advice on the best way to solve this problem--a realistic troubleshooting methodology that does not require me to spend any money. So far, I've experimented with Ekahau Heat Mapper, which is free and helps create a site survey. But I'm not exactly sure what I'm looking for or if there are other programs/tools/methods I should try as well. Any advice would be greatly appreciated. [Some background: The wireless setup consists of an HP ProCurve Mobility MSM (710?) controller that controls 10 access points throughout the building. There are three virtual wireless networks configured on the controller: one seems to be a default that cannot be changed, one is for internal employees and authenticates via Active Directory, and the third is a guest network for visitors. When I use HeatMapper, these show up as three different SSIDs, with different MAC addresses, all on the same channel. At first I thought maybe this would cause interference, but this seems to be the way the controller works;apparently, it automatically configures the channels to avoid interference from the other APs on the network.]

  • Server taking too long to respond error

    - by DCJones
    This is my first post on serverFault and my first entry in to web server configuration. The hardware and software. CPU: GenuineIntel, Intel(R) Core(TM)2 Duo CPU E7500 @ 2.93GHz OS: Linux 2.6.18-128.el5 Memory: 2Gb Background. I am running a small database (MySQL), around 1000 records with each record containing 44 fields. At the start of each day “00:01” the tables are cleared and populated with fresh data. The are 10 remote PCs all running Winodws XP and Firefox internet browser. All remote PC’s are connected to the internet using a min 4Gb broadband connection. Each remote PC runs a URL which displays a dynamic page of data which is refreshed every 20 seconds. This is a continual process 24 hours a day. I problem I am having is on odd occasions throughout the day the PC browser error with “Server taking too long to respond error”. What I am trying to find our is if I have the correct setting in the httpd.conf file on the server. Any help or advice anyone can provide would be very helpful. Best regards Dereck Server config file: httpd.conf ServerRoot "/etc/httpd" PidFile run/httpd.pid Timeout 120 KeepAlive On MaxKeepAliveRequests 200 KeepAliveTimeout 5 <IfModule prefork.c> StartServers 8 MinSpareServers 5 MaxSpareServers 20 ServerLimit 256 MaxClients 254 MaxRequestsPerChild 4000 </IfModule> <IfModule worker.c> StartServers 2 MaxClients 150 MinSpareThreads 25 MaxSpareThreads 150 ThreadsPerChild 25 MaxRequestsPerChild 0 </IfModule>

  • High Apache CPU usage, but low nginx - Configured correctly?

    - by Buckers
    We've just moved a website of ours over to a brand new high-spec Linux server (1x Intel Xeon E3-1230 v2 @ 3.30GHz, 8GB DDR3 ECC, 2x 128GB SATA SSD RAID1). The server has been configured to use nginx but we're not sure if its working correctly. The site always loads very fast to us (http://www.onedirection.net), but Plesk often sends us reports that the Apache CPU usage percentage reaches high leves, yet when we look at the nginx percentage it's always very low. We've come from a Windows background so are very new to Linux, but shouldn't nginx run INSTEAD of apache? Here's a screenshot from Plesk showing the CPU usage: http://www.pixelkicks.co.uk/_download/plesk.JPG The website gets around 20,000 visitors per day, and we use W3 Total Cache to get it running as fast as possible. MySQL has been optimised well. Memory usage is only running at 2GB of the 8GB. Does this look right? How can we tell that nginx is doing most of the work? Thanks, Chris.

  • Dell Studio 17 - turning off suddenly

    - by studiohack
    I have a Dell Studio 17 laptop, a refurbished model almost 2 years old...It is currently running Windows 7 32-bit, Home Premium. Via a clean install, it is a Vista upgrade machine...A while back, a problem started to develop while running Vista that it would suddenly just turn off. No warnings, messages, anything. It was like I had the battery out, then just unplugged it from the wall. Just like that. Over several months of this happening (or more), I've observed several things...First, it only seems to happen when I'm doing memory-intensive things, such as watching a online video full screen or running many applications in the background...Second, I can tell when it is about to "flip" as I've termed it, when the fan starts running...the computer gets really hot in places... Anyways, I'm pretty sure this is a hardware problem, because it still exists, even after a Vista-to-7 Upgrade...Is this true? Hardware vs. software? Is there anything I can do to fix this? Is it just a specific component or what? What do you recommend? Thanks!!

  • ReadyBoost in Windows 7

    - by Robert Koritnik
    I've bought an SD card today for my phot frame, but when I inserted it into my notebook I saw I could use it for ReadyBoost. Some background I'm a .net developer, using VMs and developing web applications (and Sharepoint). I use an HP notebook machine with Core 2 Duo 2GHz + 4GB RAM + 320 7200 HD. I simultaneously run Visual Studio 2010 with some plugins SQL Server Firefox with at least 10 tabs Chrome with about 5 tabs IIS VM with Server 2008 machine Sharepoint and occasionally also Photoshop and some InDesign as well. So I don't let my machine have a break. :D Question If I buy myself some really fast SDHC card (like SanDisk 16GB Extreme 30MB/s - is there anything faster) and use it with my Windows 7 ReadyBoost, will I see any performance gain? Is it going to work something similar to Seagate's HybridDrive Momentus with 4GB of solid state drive? What could I actually expect if I do put this card into my machine? And what would be recommended size? Observations I guess redirecting page file to it would speed up the system. Some VM machines on it would probably run faster as well because they could run parallel to HD host system I guess. Am I right or wrong?
