• Move 2TB Win7x64 to 640GB HDD

  - by reedacus25

  Basically I just got a new (refurbished) HP H8-1260t to use for Windows Media Center. The shipping drive is a 2TB Hitachi drive, but I have an older and barely used 640GB WD Caviar Blue 7200RPM drive I would like to move my Windows install to. I have about 750GB of data with over 1TB free left on the drive. Having googled my heart and fingers out, I would think that I can shrink my partition down to the size it is full at now with over 1TB free for a second partition where I can move my media files to further shrink my boot partition so that I can fit a system image smaller than 640GB on that WD drive. I want to have a separate drive for Media and TV Recordings from my boot disk. Does this sound like the easiest method for me? Or am I doing this all wrong. Help appreciated.

• Laptop monitor being very dark, no backlight?

  - by ldigas

  I'm asking for a diagnose of what is probably the problem. Here goes ... laptop monitor (hp 6715s) went dark. I'm using also an external monitor with the laptop, and since it kept its picture, I'm guessing it's not the graphics card. When the night came, and I turned on my desk lamp, I noticed that the laptop monitor is not really not showing anything, but is actually showing my desktop picture - only it's very very very dark. You cannot see anything on it, unless the lamp is focused on it, then you can see the picture, only very dark. Does anybody have any clue what it could be? I'm just looking for informed guessed here, so I have at least some idea of where the problem lies. The closest repair shop is quite some distance away, so going for a bit of self-diagnose before thinking of taking it to them.

• Clarification of the difference between PCI memory addressing and I/O addressing?

  - by KevinM

  Could someone please clarify the difference between memory and I/O addresses on the PCI/PCIe bus? I understand that I/O addresses are 32-bit, limited to the range 0 to 4GB, and do not map onto system memory (RAM), and that memory addresses are either 32-bit or 64-bit. I get the impression that memory addressing must map onto available RAM, is this true? That if a PCI device wishes to transfer data to a memory address, that address must exist in actual system RAM (and is allocated during PCI configuration) and not virtual memory. So if a PCI device only needs to transfer a small amount of data at a time, where there is no advantage to putting it into RAM or using DMA, then I/O addressing is fine (e.g. a parallel port implemented on a PCI card). And why do I keep reading that PCI/PCIe I/O addressing is being deprecated in favour of memory addressing? Thanks!

• Windows 7 - all usb devices go to sleep im idle mode

  - by dvdx

  A strange thing happened after a few updates to the system: Intel rapid storage SSD firmware update Intel Ethernet adapter update GPU Intel update When the computer turns off the screen (after 5 min), an unknown time later, all the USB devices stop working. Sound card Mouse Keybord etc. I can't turn them back on, so I can't wake up the screen or do anything except turn the computer off and back on. I checked my power save profile and all is OK there. I changed in the Device Manager, the Allow USB to sleep in all the hubs. How can I fix this??

• Send chrome tab from w7 laptop to w7 HTPC? (Like with iPad to AppleTV)

  - by Justin

  For the last couple days I've been trying to figure out how to get open tabs syncing between chrome installs on different computers to no avail. (if it's supposed to work the way I think it should, that is.) I have a laptop that I do all my web browsing on. Once in a while I'll come across some video that's worthy of the big-screen and the surround sound and want to open that tab (or media) on the HTPC. It'd be nice if I could just 'Right click Send to HTPC' and it opens up there with no further hassle. But even opening chrome on the HTPC and finding all my current tabs waiting would be fine. Alas, open tabs syncing doesn't seem to actually open tabs on other devices for me. Has anyone come up with a way to accomplish anything similar? Thanks all!

• Windows 7 very slow after restart, but fine after complete shutdown?

  - by lkm

  I have a Dell pc running Windows 7 with the Intel i3 processor. Whenever I restart the computer, the os crawls. For example, I move the mouse and then I see it move on the screen 10 seconds later... Everything runs slowly. This happens only on a restart (it's fine when I turn it on after it has been shut down). Any ideas what is causing this (I haven't installed any new software since buying it). Does it sound like a hardware or software issue?

• Why are browsers so heavy?

  - by Kaivosukeltaja

  Back in 1998 I had a computer with 233MHz Pentium MMX CPU and a GFX card with no 3D acceleration. It was able to run games like Quake II at a decent FPS rate. My current computer has tons more performance and a mid-class GPU, yet struggles to reach 20 FPS when rendering a single model inside a skybox with WebGL. Even regular pages with lots of 2D CSS animations bring many modern computers to their metaphorical knees. As a web developer I understand there's a lot going on in a web page but not what makes it that heavy. Modern browsers compile JavaScript to CPU native machine code before running it and rendering into a canvas element shouldn't trigger DOM rebuilds so theoretically it should be a lot faster than it is. What am I missing here and is it possible to avoid or minimize whatever is making the browsers slow to build more efficient websites?

• Running Ubuntu off a USB drive?

  - by Solignis

  I was wondering if a USB 2.0 Thumb drive has enough bandwidth to act as a primary system drive in an Ubuntu Linux server. More specifically an SAN server. I am running an iSCSI target, ZFS and NFS-kernel-server, BIND9 (Slave), and Openldap (Slave). I was thinking of resorting to a thumb drive because my new motherboard only has 4 SATA ports and I have 5 disks. 4 (ZFS Pool) 1 (System). And unless I get an expansion card there is no way to get more SATA ports. This "server" leans more twords a home server. I use in my lab with my VMware server. It provides storage, or atleast it did until it died. Would it still be better to go with the SATA hard disk?

• Kvpn on ubuntu 11.10 is stuck on 'Connecting'

  - by xupv5

  I recently installed open-vpn and it's gui, Kvpn, on my ubuntu system but after I load the configuration file and click 'Connect' it just runs through and gets stuck on 'Connecting', never actually getting connected. How do i get around this or what might i be doing wrong? The profile was set up using a .conf file and the network i'm trying to connect to needs only a username and password. I'm on a wi-fi connection, with one network card(also behind a university firewall, i suppose). Any help regarding connecting to a vpn on ubuntu would be much appreciated. Thanks!

• Has anyone seen an HTTP 500 error when HTTPS traffic going through Pound Proxy forwards to an HTTP page?

  - by scientastic

  We have Varnish as our load balancer and reverse proxy cache for normal HTTP traffic. For HTTPS traffic, we use Pound proxy to unwrap the SSL and forward to Varnish, which then forwards to the back-end servers. This is used for our "checkout" process to encrypt credit card info in transition. However, on the last stage of checkout, users are always getting an HTTP 500 (Internal Server) error. It doesn't seem to be due to our back-end app server, by all tests I've tried. Does anyone know anything about how that transition works-- the transition back from HTTPS to HTTP and the interaction between Pound and Varnish-- and why it might cause 500 errors?

• Third monitor randomly defaults to 640 x 480 on startup

  - by ajbdev

  I purchased a PowerColor HD 5770 video card so I could get a third monitor working. I have two widescreen monitors, one attached via HDMI and the other attached via DVI. My third monitor is attached from DisplayPort to VGA (using a passive connector like this one) The third monitor is a 19" Hyundai L90D. I was unable to find any Windows 7 (or Vista for that matter) drivers for the monitor, so it's stuck with "Generic Non-PNP Monitor". It's native resolution is 1280 x 1024. Randomly Windows will boot up in the correct native res, but sometimes it boots up in 640 x 480 res. When it does boot up into 640 x 480 res, the screen resolution slider is stuck and I cannot slide it back to 1280 x 1024. I cannot find a pattern for when or why it will do this, I've tried rebooting five or six times in a row at times to get it to boot into native res, but this doesn't always work.

• how to disable to automatic wireless interface up in ubuntu? [closed]

  - by Surjya Narayana Padhi

  On my laptop I have a built in wireless card and I got one external connected via usb. By ifconfig command I saw both the cards connects to internet and gets IP. eth1 - the interface my laptop has in-built wlan1 - I have connected externally via usb. Now I applied "sudo ifconfig eth1 down" so that i can use only wlan1. But this eth1 goes down for sometime and then come up again automatically. So I am not able to test my externally usb connected wifi adapter. Can anyone suggest me way to disable eth1 interface?

• Is it possible to use the same MAC address for an entire subnet?

  - by Bruce

  I wish to add static entries to the ARP table of my machine so that it uses a dummy MAC 00:11:22:33:44:55 for any IP address within the subnet 10.0.0.0/8 Using arp -s 10.0.0.0/8 00:11:22:33:44:55 does not work. What can I do? PS - I know it might sound strange why anyone would want to do this but kindly bear with me here. EDIT: I am using this so that the hosts do not send a broadcast ARP message. I route the packets to the appropriate last hop router which changes the dst MAC from the fake MAC to the MAC of the dst IP address. I can get everything working except I have to manually enter the fake MAC for each subnet IP address.

• Nvidia driver on Windows 7 causing black screen

  - by inKit

  I have just installed Windows 7 on a desktop machine and for the first time ever have had a really tough time doing so, its normally a nice smooth install. This time I found that the monitor would simply go black after completing the installation. I tried reinstalling about 3 times and this did not help. After much searching I discovered that it was the nvidia drivers that were playing up with win 7, so i booted into safe mode, disabled the device, then rebooted to complete the installation. Windows 7 now works fine as long as the nvidia 9600 gt video card is disabled. The moment I enable it, the system requires a reboot and the screen will go black before even getting to the log in screen. I have tried downloading the latest driver and installing it manually, I have also tried uninstalling the device and allowing windows 7 to install it itself. Nothing seems to work. any clues?

• Windows 7 cannot connect wirelessly to Netgear Router WPN824 V2

  - by edo152

  I have a new HP Laptop running Win 7 Home Premium with an Atheros Wireless card. I have a Negear WPN824 V2 Rangemax Router. The router works with a wired connection. Wirelessly it can see the network but it cannot connect. I have searched the web and the WPN824 seems to work for some people, but I cannot get it to connect. I have tried disabling Bonjour Service and a few other things but it continues not to connect. Am I probably correct to assume that the WPN824 is somehow incompatible with Wiondows 7? or am I missing some simple change I should make?

• Is the quadro 4000 still worth it's price? [closed]

  - by aknewhope

  I am going to be purchasing a quadro graphics card for learning 3d CAD at work. It's not critical I have it right now otherwise I would just buy the current 4000 (PC). I am buying this with my own money and am concerned Nvidia will release a new Quadro 4000 sometime in the near months. Is the current 4000 still worth it's price tag at $700.00? If i were to purchase it, how long would it be useful? I am going to be running E-PLAN, SOLIDWORKS, DRAFTSIGHT, MASTERCAM. My computer is a second generation i7-2600k with z68 chipset (intel DZ68BC mobo).

• Can I create an Infrastructure access point from built-in WiFi (as opposed to Ad-Hoc) on Windows XP?

  - by evilspoons

  I want to use my Windows XP laptop as an access point. What I am trying to achieve is possible under Windows 7 with a myriad of utilities, but the wireless driver stack was different before Windows 7 and those specific APIs don't exist on XP. The reason behind me wanting to do this is that I would like my Android phone to be able to connect via WiFi to a network that is only hard-wired (reverse tethering). Unfortunately, my Android device (Galaxy S Captivate) does not support ad-hoc networks without a serious amount of screwing around. Is it possible to create an "Infrastructure" network with my Dell Latitude D830's built-in WiFi - a "Dell Wireless 1395 WLAN Card", which I am assuming is probably rebadged Broadcom, or is there some fundamental difference between a wireless adapter and an access point that would prevent this?

• Visual indication of network activity

  - by at.

  is there a simple application which can sit on top of a fullscreen game to give me an indicator of when there is a lot of network activity? I can only seem to find system tray apps or programs which work outside of fullscreen games. Preferably something transparent so i can see through it. A little background info: I used to have my PC sitting sideways on my desk so I can see lights from the network card. The lights stopped working a while ago and all I need is a little blinking application to tell me when there is activity. I do not need a detailed graph or bandwidth usage, just activity notification. I've looked everywhere for something, maybe you guys are better at searching than me.

• My wireless network slows down every 7.5 minutes when my desktop is switched on

  - by Dog Ears

  My network has lag spikes lasting for a few seconds every 7.5 mins. The spikes also effect any other computer connected connected to my wirless router at the time. My wife has to connect her laptop via a cable to prevent the lag causing problems when she's VPNing into her work. If I switch my PC off the problem goes away! I've got an Edimax 7728ln 802.11n wireless card and Speedtouch 585v7 (I'm with Be) I've Tried... Updated the drivers from Edimax website: 2.0.3.0 (it does say 3.0.2.0 in devices properties though) WLAN Optimizer doesn't seem to be helping What can I do?

• Why does using 2 memory sticks cause my computer to crash?

  - by hi

  My computer randomly crashes when playing games, but if I remove one memory stick (it does not matter which one I remove), it does not crash anymore. Memory tests do not find errors, I just put in a new power supply (650W), I only have 1 graphics card, so why is this happening? BTW, they are the same memory, same vendor same specs, everything I bought it together (2x2GB) My motherboard is a Asus P5Q Pro, so it supports both dual channel and more than 4gb. Switching slots does nothing, as long as I don't use more than 1 I'm fine.

• RAID strategy - 8 1TB drives

  - by alex

  I'm setting up a backup storage device- This machine has Windows Server 2008, on a separate boot drive. It has 8x 1TB drives, and uses a hardware RAID card. My question is, which RAID configuration should I go for? Initially, I was going to go with RAID 5 across all 8 drives, however members on serverFault have advised against it. I was just wondering why? Some people have suggested 2 lots of RAID 5 configuration on 4 of the drives, then striping them... I want to maximise the storage space, as this is a backup unit - will store SQL backups, Acronis Images, files, etc... It won't be for public access, so the I/O won't be that high I wouldn't think.

• Random BSOD ntoskrnl.exe (Windows 7)

  - by nordbjerg

  I get BSOD at random times and have been for a while now on my Windows 7 machine. It is really new, and I already tried wiping the graphic card drivers and installing them again (making sure that they are of course up to date). I get a variety of bug check strings on a few different drivers. The single file that is in all of my BSODs is ntoskrnl.exe Bug Check Strings - SYSTEM_SERVICE_EXCEPTION - KMODE_EXCEPTION_NOT_HANDLED - DRIVER_IRQL_NOT_LESS_OR_EQUAL - SYSTEM_THREAD_EXCEPTION_NOT_HANDLED - PAGE_FAULT_IN_NONPAGED_AREA I would rather not resort to getting a completely new PC, as I have already thrown a lot of money on my current one. Here is a .zip file with my dumps.

• Temporarily block other users from network printer

  - by TecBrat

  I found where someone else asked this question here, but they did not get a working answer. We have a printer that is shared. It has it's own network card, so we all have equal access to it. (none of our computers owns it) One of our users needs to print on specialty paper and we need to be sure not to print when that paper is in the printer. Our current method is "Hey, don't print anything right now!" Obviously this method is not preferred because it does not enforce itself. :-) I think all our PCs are running Win7 Home. The printer in question is an HP Laserjet 2200. Is there a way that we can make this happen?
