• Extremely Weird Computer Problem

  - by waiwai933

  Well, having worked with computers a long time, I thought I had seen everything that could go wrong with a computer. Today, I learned that I was wrong. My Mac has been behaving extremely weirdly. While the keyboard is fine, the mouse holds extremely weird behavior. It will open apps from the Dock, but not open documents from a Stack. The top menu bar will work, but only after I restart Finder. I am unable to close most windows, except with Cmd+Q. Clicking on a link in Safari, for some reason, opens it in a new tab. I can not select checkboxes, but I know a click is going through because you can see a quick indent in the check box, before it reverts to the unchecked state. I've restarted my computer, as well. I don't see a virus when looking through top, but I guess it could be subverting top. Does anyone have an idea what is going on?

• How to get back the themes feature in Windows XP?

  - by Martín M.

  When I try to set a visual style in Windows XP (the standard Luna, for example), I get one of these two: "Access denied" error. It works, but when I restart the computer, I get the Classic look again, with no errors. Also, the "Windows and icons" dropdown is grayed out in the "Appearance". This is a list of things I have tried, with no results: Making sure "Use visual styles on windows" is checked on System Properties Advanced Performance. Restarting the "Themes" service. It starts cleanly, no errors. Applying these two fixes: Kelly's Corner and tweaks.com. Running sfc /scannow and checking the integrity of uxtheme.dll against a clean installation of XP Restoring the whole \Windows\Resources\Themes directory. Creating a new user. The new user does not seem to suffer this problem. Maybe this is the solution, create a new user and migrating all the data, but it would be a pain, and I would prefer reinstalling the whole thing. I am using Windows XP Professional SP3, with no spyware, no virus, and no other visible malfunctions. How can I fix this?

• ClassNotFoundException returned for all plugins

  - by razumny

  I am trying to use a Java applet (any Java Applet), but I always get a messages saying "Error. Click for details". When I do so, the pop-up says: Application Error ClassNotFoundException jreVerification.class When I click the "Details" button, all I see is the following: Java Plug-in 10.7.2.10 Using JRE version 1.7.0_07-b10 Java HotSpot(TM) Client VM User home directory = C:\Users\razumny ---------------------------------------------------- c: clear console window f: finalize objects on finalization queue g: garbage collect h: display this help message l: dump classloader list m: print memory usage o: trigger logging q: hide console r: reload policy configuration s: dump system and deployment properties t: dump thread list v: dump thread stack x: clear classloader cache 0-5: set trace level to <n> ---------------------------------------------------- I am running Windows 7 Professional, and am up to date on patches.

• Network card/driver stops under heavy load

  - by Uwe Keim

  Since about approx. 2 month, I do have the following issue with my approx. 1 year old development machine (Windows 7, 64 bit): When doing network intensive operations, like e.g. executing some SQL script on a remote SQL server to select or update 1000 of records, the network card stops working. I.e. suddenly, No network connection is present anymore. No internet, no local connection, simply nothing. The only resolution so far I found is to disable my network card and then simply enable it back, like in the following screenshots: 1.) Click "Deactivate" 2.) Click "Activate" (German screenshots only, sorry) Now this is an acceptable solution to work around this issue, but I would love to have this fixed, since it suddenly stops me from working when I'm connected remotely via VPN/RDP on my machine (Win7 64bit). So my question is: Could you imagine a possible cause for this issue and give some hints how to hunt/resolve it? I could imagine that this is a driver issue, a hardware issue or even some kind of background software issue like a software firewall or a virus scanner.

• Weird File Corruption

  - by Viet Norm

  My Windows 8 broke few days ago and I had to reinstall it (see Can't boot Windows 8). Afterwards, I found some corrupt files on C drive. Ok, it happens, but this is really weird. Corrupt files seem to contain stuff from Windows registry. For example, this is beginning of one of the corrupt files: hbin ` PÿÿÿT h i s z o n e c o n t a i n s w e b s i t e s t h a t y o u t r u s t n o t t o d a m a g e y o u r c o m p u t e r o r y o u r f i l e s ... I googled and found that 'hbin' often refers to "hive bin" of Windows registry. Then I searched the registry for the readable part of corrupt data, and found the text in some registry value (not the text above, but something I found in another corrupt file. I'm assuming the above is also from registry). My question is, how could this happen? Was it a virus, or did Windows somehow corrupt these files while attempting to repair itself?

• How do I install Windows XP from an external hard drive?

  - by Plasmer

  I'm trying to install Windows XP Media Center edition by copying the install disc image to an external hard drive and making it bootable. Has anyone had success getting this to work on systems that can't boot from dvds/floppies? I'm basically working from this guide: http://www.dl4all.com/other/21495-install-windows-xp-from-usb.html Update - 2/15/10 I used WinToFlash on my laptop to format my usb hard drive from my install dvd (Windows XP Media Center Version 2005 with Update Rollup 2 from Dell) and selected "boot from usb device" at the boot selection menu and the windows installer started up. However, an error message came up saying that: "A problem has been detected and windows has been shut down to prevent damage to your computer." Originally on my desktop machine, I had 1 150Gb SATA drive, and 2 150 Gb SATA drives striped together using RAID. From the hard drive diagnostics, it appears the windows install on one of the RAIDed disks lost a block and this has been preventing me from booting up. I replaced the standalone drive with a new 1Tb SATA drive and disconnected the other hard drives. Could the message be indicating a virus is on the unformatted drive? or the usb hard drive? Update 2 - 2/15/10 The external hard drive didn't find any viruses when scanned. I tried installing Vista Home Premium 64bit SP1 using WinToFlash and that installed successfully onto the new 1Tb drive. WinToFlash was really easy to use and helped a lot, thanks!

• Exchange 2010 sends out spam.

  - by Magnus Gladh

  Hi. I have an Exchange Server 2010, that uses a smart host to send out mails. A day ago the owner of smart host contact us and told us that we send out spam. I have try different open relay test on the net and all of them come back saying that this server is secured and can not be used as relay server. But I can see in my Exchange Queue Viewer that it keeps coming in new messages. Here is an example of how it looks. Identity: mailserver\3874\13128 Subject: Olevererbart:: [email protected] Pfizer -75% now Internet Message ID: <[email protected]> From Address: <> Status: Ready Size (KB): 6 Message Source Name: DSN Source IP: 255.255.255.255 SCL: -1 Date Received: 2010-12-09 21:46:22 Expiration Time: 2010-12-11 21:46:22 Last Error: Queue ID: mailserver\3874 Recipients: [email protected] How can I secure our exchange server more, to stop this from happening? Could I have got an virus that hooks up to our exchange server and send mail throw that? As I can see the From Address is always <, is there someway that I can stop sending mails that don't have a from address that I describe? Pleas help

• Mysterious Windows 7 slowdown problem

  - by cletus

  I have a fairly beefy machine: Intel Q9450 8GB DDR2800 (4x2) Intel X25-M G2 80GB SSD Several other hard drives Windows 7 Ultimate 64 In the last month I've gotten a mysterious slowdown problem. When I start my IDE (IntelliJ IDEA) it usually takes about 20 seconds on the SSD. If my machine has been on for a day or two (as far as I can tell this is the only pattern) and I try to start the IDE, it brings my machine to a halt. CPU usage goes up to 25% per core (so it's basically 100% usage) and it takes up to 5 minutes to start. Other things I've noticed: iTunes will start to skip and stutter (my music is running off a second hard drive). The only persistent things I'm running are: AVG Anti-Virus Spybot (the slowdown predates this) Hamachi and Murmur (again the slowdown predates this) Apple Airport Base Agent HP OfficeJet 8500 driver/manager The browser I use is Chrome. I can't think why that'd be relevant but it's always on so I thought I'd mention it. When this happens I can't see a reason for it in the process list. No CPU hogs. No spikes in IO activity that I can see. Basically I'm at a loss to explain it and need to reboot, at which point everything returns to normal (for awhile). FWIW the Intel SSD is about 75-80% full. I know being too full can really degrade performance. I don't believe that's the issue here. Does anyone have any ideas on what I can do to fix this or at least help find what's going wrong? This same machine (sans SSD) could run Win XP and stay up fine for a month or two.

• Binary Search Tree for specific intent

  - by Luís Guilherme

  We all know there are plenty of self-balancing binary search trees (BST), being the most famous the Red-Black and the AVL. It might be useful to take a look at AA-trees and scapegoat trees too. I want to do deletions insertions and searches, like any other BST. However, it will be common to delete all values in a given range, or deleting whole subtrees. So: I want to insert, search, remove values in O(log n) (balanced tree). I would like to delete a subtree, keeping the whole tree balanced, in O(log n) (worst-case or amortized) It might be useful to delete several values in a row, before balancing the tree I will most often insert 2 values at once, however this is not a rule (just a tip in case there is a tree data structure that takes this into account) Is there a variant of AVL or RB that helps me on this? Scapegoat-trees look more like this, but would also need some changes, anyone who has got experience on them can share some thougts? More precisely, which balancing procedure and/or removal procedure would help me keep this actions time-efficient?

• Good references to know why has my computers stopped responding me

  - by Peterstone

  Hello all! I´m a windows xp user (but not for much time...) and I usually see how my computer stop of responding me. The process is this: Firsly it became totally stopped or very slow for certain periods of 5 minutes. How could I do? After that it gets stopped (Even not totally because If I click on the bar I see a blinking response in the bar botton of the program I click on. It´s could be anything related with security (like the firewall or some virus)? Computer university: I usually experience this, using Matlab (R2007a) with System Generator (its respective compatible version) My personal laptop: It´s usually works well but when stopped periods became to appears I know in not much time it will became totally stopped. I usually see how Word 2007 get stopped and after a while my windows xp gets stopped. (well I can access to the the manage task pressing ctr+alt and...). The only solution I see is to kill program by program... My petition: Please, I need good references that help me how to think in order to avoid or to manage the problems previously described.

• Router drops internet connection if I connect an additional pc

  - by BluePerry

  Hey, I'm using a SMC2804WBRP-G router connected to my ADSL-modem. Usually there are two computers connected to this router: a win7 ultimate desktop(wired) and a macbook air (wireless). Both working absolutely fine and never caused any connection drops as far as I know. A new room mate moved in last month and each time she starts up her win7 home laptop the router looses the internet connection. The laptop is on a wired connection. The first time she connected to my router, the connection dropped every 2 mins. To find out whats wrong with her machine I disabled all unnecessary services etc. besides the anti virus software. That helped to eliminate almost all of those periodic connection drops. But the start up drop remained and I've got the feeling that the router is still loosing connection from time to time. I haven't had the time to find out what service caused the periodic drops. But I'm more concerned about is that start up drop. Can anyone point me in the right direction to look for the problem? I would be very thankful for any hints or tips!

• Software to monitor bill payment to mission critical IT service providers (ISP, DNS etc.)

  - by Sholom

  Hi All, The Problem: Our very likable but absent minded bookkeeper keeps neglecting to pay our IT vendors on time. Just this past week our internet service was disconnected. Same could happen to many other mission critical accounts (domain registrar, backup MX, anti-virus license, HackerSafe (McAfee secure) service and even an 800 number to name a few). As the sysadmin, i monitor my severs to make sure they are plugged into the power-outlet. I believe i should also monitor my services to make sure they are plugged in to their money-outlet. To compound the problem, when the power goes out someone else will likely notice and notify me. But if a bill is not payed, no one will ever notice until service is lost. Lost as in losing our domain name which would cause a lot more damage then the power failing on our server. [Solution] = [Doesn't work because]: Retrain the bookkeeper = Wishful thinking. Notify my manager = Already have (via email). Protects me, does not solve problem. Fire bookkeeper = What makes you so sure the next one will never forget? Bottom line: Humans are humans and sooner or later something critical will be royally messed up. We need to partner with a machine to help us out here. Anybody have the same problem? What software/solution do you use? I would like software that emails me when a bill is passed due just like i get an email when the power outlet fails. Anyone hear of anything like that? Thanks

• How to eliminate duplicate nodes bases on values of multiple attributes?

  - by JayRaj

  Hello All, How can I eliminate duplicate nodes based on values of multiple (more than 1) attributes? Also the attribute names are passed as parameters to the stylesheet. Now I am aware of the Muenchian method of grouping that uses a <xsl:key> element. But I came to know that XSLT 1.0 does not allow paramters/variables in <xsl:key>. Is there another method(s) to achieve duplicate nodes removal? It is fine if it not as efficient as the Munechian method. Update from previus question: XML: <data id = "root"> <record id="1" operator1='xxx' operator2='yyy' operator3='zzz'/> <record id="2" operator1='abc' operator2='yyy' operator3='zzz'/> <record id="3" operator1='abc' operator2='yyy' operator3='zzz'/> <record id="4" operator1='xxx' operator2='yyy' operator3='zzz'/> <record id="5" operator1='xxx' operator2='lkj' operator3='tyu'/> <record id="6" operator1='xxx' operator2='yyy' operator3='zzz'/> <record id="7" operator1='abc' operator2='yyy' operator3='zzz'/> <record id="8" operator1='abc' operator2='yyy' operator3='zzz'/> <record id="9" operator1='xxx' operator2='yyy' operator3='zzz'/> <record id="10" operator1='rrr' operator2='yyy' operator3='zzz'/> </data>

• How to fix IE starting when I try to start Opera?

  - by Scott Leis

  I have a problem that started today, where trying to run any of the 3 versions of Opera I have installed causes Internet Explorer to start instead. The Opera versions I have installed are 9.64, 10.10, and 10.63. My OS is Windows Vista with the latest critical/important updates. The behaviour is the same regardless of whether I double-click a shortcut to Opera, double-click on Opera.exe in one of the install directories, or run Opera.exe with the full path from Start-Run. The only work-around I've found is to right-click Opera.exe or a shortcut, and click "Run as administrator". This starts Opera, and it appears to work normally. Opera seems to be the only program so affected. I've checked Firefox and a few other (non-browser) programs, and they work normally. When IE starts instead of Opera, there are always two instances of iexplore.exe started, and they both crash before I can do anything else. IE also crashes if I try to start it from its own shortcut, but I don't know if that only started today, since I hadn't used IE for a few weeks. Does anyone know what might cause this and how to fix it? It's possible my PC has a virus, but BitDefender (for which I have automatic updates enabled) hasn't detected anything.

• SVN checkout returns 400 error

  - by eboix

  I'm trying to download the http://code.opencv.org/svn/opencv/trunk/ repository of all of the OpenCV source code - as specified in an OpenCV installation tutorial. In the tutorial, the repository https://code.ros.org/svn/opencv/trunk/ is used, but they moved it to http://code.opencv.org/svn/opencv/trunk/, and now you need a password to access the code.ros.org repository. Anyway, I'm using TortoiseSVN to download the SVN repository. (I get the same error with http://sourceforge.net/projects/win32svn/) I get this: Checkout from http://code.opencv.org/svn/opencv/trunk, revision HEAD, Fully recursive, Externals included Server sent unexpected return value (400 Bad request. Method Unknown) in response to REPORT request for '/svn/opencv/!svn/vcc/default' On the TortoiseSVN site I found something about this 400 error: You're behind a firewall which blocks DAV requests. Most firewalls do that. Either ask your Administrator to change the firewall, or access the repository with https:// instead of http:// like in https://svn.collab.net/repos/svn/ That way you connect to the repository with SSL encryption, which firewalls can't interfere with (if they don't block the SSL port completely). Also some virus scanners (i.e. Kapersky) are known to interfere and cause this error. The code.ros.org repository is https://, so I would be able to access it, but I need a password, so I can't. I made an account on ros.org, but it seems that I still need a password (which I don't know) to access the code repository. My username-password combination does not work. I unblocked all of the TortoiseSVN programs in my firewall settings. Nothing changed. I temporarily stopped my firewall to see if it was interfering with my request. I got the same error. How can I do an svn checkout http://code.opencv.org/svn/opencv/trunk/opencv/ so that I don't get this error? Is there any way to make it https://? Any help would be appreciated!

• Connection to Google, Yahoo, Bing, Ask, etc. compromised via all devices on my home network - How?

  - by jt0dd

  I'm a very computer savvy guy (although not very networking savvy), and I may still be wrong about this, but I think my home network may be compromised somehow. I'd like to know if it's possible for someone to have hijacked my network's connection to Google.com and other popular websites. Update: The issue seems to take effect with all popular websites. I can connect to small (non-popular) websites without issue, but Facebook, Google, Yahoo, and Bing cannot be accessed by any device on my home network. On all devices using my home network, I'm being shown http://www.google.com WARNING! Internet Explorer is currently out of date. Please update to continue. when I attempt to connect to google.com. I wouldn't be surprised by this at all if it were just the laptop. It's the fact that this is happening on all devices on my network that confuses me. Here's the screenshot from my iPhone, for reference. Can my home network be compromised? Is that even possible? How can something like this happen across all platforms on all devices in the same way? I wouldn't imagine every device / platform on the network would get the same virus. Should I assume that my network's security is totally compromised? Update: All mobile devices and laptops on my home network are experiencing the same alert when attempting to connect to google.com.

• RSKeyMgmt -r unable to remove installtion ID

  - by Eves

  I have backed up databases on one 2005 SQL Server and have restored those databases on a second 2005 SQL Server. I am currently trying to remove the new server's OLD key instance ID using the Reporting Services Key Manager (RSKeyMgmt -r). Prior to running the removal command the list of the current instances shows the new server's OLD instance ID as well as the NEW instance ID from the first SQL Server. Executing the RSKeyMgmt -r command results in: "The command completed successfully". However, when I recheck the listing of current instance IDs I see both the OLD and NEW instance IDs. In addition, when I check the Application Event Viewer I see an error: Report Server Windows Service (MSSQLSERVER) has not been granted access to the catalog content Does anyone know why I would be getting the above application error? Or...does anyone know what I would need to do to give access to the catalog to the Report Server Window Service? The first SQL Server where the databases were backed up is an Enterprise edition SQL Server and the second SQL Server where the databases were restored is Standard edition. Could this be the cause of the problem? Is there a way to make this backup and restore migration work?

• Control Panel as menu includes a blank item

  - by Matthew Ferreira

  When viewed as a menu attached to the Start Menu in Windows 7 Ultimate x64, the Control Panel contains a blank item. It looks like this: This item cannot be deleted or removed. I also cannot create a shortcut to it. No error message is displayed, instead simply nothing happens. I've tried using Shell Object Editor (using Run as Administrator) to find out if there is an errant entry on the Control Panel, but many entries (almost two dozen) are blank. There are several valid entries as well. I've looked through the registry and through C:\Windows, \system32, and \SysWOW64 but have had no success. I looked at this question, but I am not using Windows XP and thus have no option to use Tweak UI's Rebuild Icons function. Please note that this is no empty entry in the Control Panel when opened normally, only when attached to the Start Menu as a menu. I have compared the list of entries on the attached menu to the normal Control Panel and other than the blank entry, they are exactly the same. Nothing is missing from one or the other. I've also compared the menu and the normal view to reference images and lists of Control Panel items and have found no irregularities. Is anyone familiar with this problem or know of a solution? I've performed virus and malware scans and found nothing. I've used CCleaner with no change. Nothing with Shell Object Editor. Nothing with Registry Editor. Certainly someone here knows how to fix this. My only guess is the many blank entries visible in Shell Object Editor, but I am reluctant to delete that many items without further analysis and guidance. I appreciate your time and consideration.

• Why does Windows Firewall want to block Google Chrome today?

  - by hippietrail

  I've been using the same public Wi-Fi (staying in a guesthouse) for over a week now. But this morning for the first time I got this puzzling warning from Windows Firewall: Why does Windows Firewall want to block one of the world's most popular web browsers today after being fine with it for years, and being fine with it on this connection for a week? Could it hinge on the words, some features? If so could it be something like a rare or new feature of Chrome that uses a different HTTP port? And if so why doesn't the security alert tell me any more about it? Or could it be a known bug in Windows Firewall? Or perhaps a known virus etc attaching itself to Google Chrome? Or is there a chance it's related to "Other browser makers follow Google's lead, revoke rogue certificates"? I haven't restarted Chrome for days and have downloaded but not installed a Windows update from a few days ago. So I'm not sure what may have managed to change on my machine since yesterday.

• unable to copy file to folder, permission denied without explanation

  - by ValekHalfHeart

  Recently Norton Internet security deleted ml.exe (an assembler I use to program in masm32) off of my computer, thinking that one of the programs I had written with it was a virus (it was most certainly not). Fortunately, I had a copy of ml.exe backed up in an external hard drive, and tried to copy it over to my computer. The old ml.exe was located in C:\masm32\bin, so I tried to copy the new one to that location. After disabling Norton (which had opened the folder and preventing me from accessing it), I am still unable to copy the new file to C:\masm32\bin. When I tried, Windows announced that I would need Administrator permission to copy the file. Since I'm an admin, I figured this wouldn't be a problem although it was unexpected, as I have never had to provide administrator permission to access this folder before. However, instead of prompting me to enter my password, Windows simply refuses to copy the file: I repeat, I was not asked to provide a password. It simply says that I do not have permission. Does anyone know what's happening and how to fix it? Is Norton still causing problems, or it something else?

• Laptop Overheating with Windows 8

  - by Dany Khalife

  I recently installed Windows 8 on my HP G62 Laptop and i have been noticing a very strange problem with it. Let alone, for lets say 5 minutes, without even touching it, it starts to heat up and it reaches about 60 degrees (Celsius) with absolutely no applications open (not just on desktop but overall). I dug in a little deep and found out that Maintenance was running when the computer was Idle, so i turned that off From the System's Task Scheduler, and while there i also turned off other services i did not need hoping that would solve the problem. So after a few days, i noticed that the average temperature of my laptop dropped from 55 to 48 degrees while working on Visual Studio. And when i thought the problem had disappeared, it still did show up, only not after 5 minutes, but more like 10 minutes... Here is what i have done so far: Replacing the thermal paste on the CPU and the fan and cleaning the fan (this was like 6 months ago) Using a laptop cooler Running a virus scan (i just formatted my laptop so it would be really weird if i already caught something but who knows) Right now, i believe it has something to do with my gfx driver (Even though it IS up to date, looking closely at the screen, i can see the pixels slowly refresh (kinda like watching static on TV) which i wasn't able to do on Windows 7. If you have any ideas, let me know. Thanks

• Implementing emailing (bulk & event based) features for my website.

  - by Kabeer

  Hello. For my upcoming social networking website, I am looking for suggestions on the best way to implement emailing. Here are some of my requirements and constraints: Requirements: - Should be able to send emails based on events (new registrations, change password, etc.), promotions (advertisements based on user consent), bulk mails (newsletters), reminders (profile updates), etc. I hope I got the point through. - Should be able to process faults (incorrect email address, mail-box full, etc) - User initiated invites (inviting friends to connect) Constraints: - As of now I am looking at Godaddy for hosting. Subsequently I shall move to, may be Amazon Cloud. Godaddy seems to be excruciatingly conservative (not bad always) when it comes to the ability to send email. - My tests on Godaddy so far have been discouraging. There is limit to no. of emails I can send and sometimes if emails carries special characters it throws strange exceptions like there was a virus affected attachment (even though I hadn't attached a thing). The replies from Godaddy support have been equally funny. My intent is not to portray Godaddy as wrong but I am looking for a work-around that frees me from said constraints. I am looking for a mechanism / service that is either free of very cost effective. I wonder how other sites address this. Mine is a .Net / Windows based application.

• Windows shutting down, CPU maxing out in Windows-7 32-bit? [closed]

  - by Vivek Sharma

  I have no idea, what is happening to my laptop. For last 5-6 times it has automatically shutdown while running, without doing anything serious. And I even do get the message during boot which says - Start windows normal - Start in safe mode It just boots up normal. Few days ago, my screen blinked and it the PC shutdown immediately. After that I was not able to get it started. I got it repaired, the guy said he has replaced the display chip (nVidia-nvs-140), but i seriously doubt that. Now it started working, but would shutdown every 20 mins or so. I have a dual boot, ubuntu-11.10 works just fine. Virus scan on windows shows nothing. I am pasting my perfmon output. My CPU for reason is maxing out to 100% continously, for windows internal processes. Please have a look at the attached file. Strangly now for last 2 hours it is working fine, but i am just writing emails and reading excels. ThinkPad T61 | t9300 | 3gb | nVidia 140 nvs-quadro (latest driver 296.10) What do you suggest?
