My Specs:
Dell Dimension E521
Windows XP SP3
Athlon X2 1900mhz
GeForce 9500 GT
2GB Ram
2 SATA drive(1 80gb, 1 500gb)


Problem:
My computer would occasionally freeze but my mouse would still work. Mouse would still move and click but the application and computer will have no response to it. Ctrl+Alt+Del, Alt+F4, Ctrl+Shift+ESC will have no effect when it freeze. There is no specific application that freeze my computer. It will freeze when I'm using Firefox, IE, or just watching a movie. The time are random as I have gone 4 hours straight without freezing when downloading files. It does seem like it has a higher chance to freeze up when I use more memory intensive application.

When it started:
Started this Tuesday July 14, I was in the process of updating Malwarebytes' Anti-Malware and I opened a window that cause several pop ups. I closed all the windows and then after a few seconds the computer freeze. At the time, Malwarebytes was just about to install the updated client and was in the middle of it but it freeze along with my computer. After I hard boot the computer back on, I started to use Firefox to contine to browse the internet but after a few minutes it will freeze again.

What I have tried:

I have reinstall Malwarebytes' Anti-Malware after the fail update and ran a scan to clean my computer. I have also use SuperAntiSpyware to clean my computer. I've use the Eset Online Scanner and Symantec online scanner to check for virus.

Then I uninstall Firefox and Malwarebytes' Anti-Malware and still I have the problem. I went to Windows Update to get all the essential updates, upgrade IE from 6.0 to 8.0, and defrag my hard drive using Diskkeeper. I scan my HD with HDTune, repair registry with Advanced System Care, and finally use System Restore to go back to July 10th.

Then to check for hardware problems, I used Dell's Diagnostic Tool at boot up to test my hardware component and they all passed. Use Memtest86 and test my RAM with no problem either.

I tried running Windows for a while in Safe Mode with Networking to browse the web and it freeze after a while also.

Something weird happen yesterday, I tried to use the computer to play Street Fighter 4 on PC and everything was fine but in the middle of the first match the sound stop and I could feel that Windows has freeze again BUT I was able to continue to finish the match with no sound. After the match, the computer would then completely freeze.

I have no idea what is causing the lockups as there is no message or BSOD. There is also no specific appilcation that is causing the lockup. The lockup would just happen randomly though there is a higher chance to lockup if a more intensive application is running.

I would appreciate any help that is given as I've run out of ideas.

First...try checking for possible overheating. Ensure that all fans are operating properly...check the CPU temperature in the BIOS right after a freeze...open case and check for cleanliness.

Computer Cleaning Information - http://www.computerhope.com/cleaning.htm

You also might want to try this utility for monitoring temperatures: Core Temp - http://www.alcpu.com/CoreTemp/

The second thing I suggest...check Event Viewer for errors (no information items) which might provide clues to system problems.

If you haven't done so already, you may want to Disable Auto Reboot On System Crash - http://www.theeldergeek.com/auto_reboot_on_system_crash.htm

You might also want to do a search of your system...for any .dmp files which may exist. When setting the parameters, you want to search all hidden and system files, in addition to any other files. The search string would be *.dmp and this would be entered as All or part of the filename.

Don't think is overheating as I've even try openning up the case and use a big fan to blow it while using the computer but it still froze. I'll try to use the temp tool to see if it comes up with anything.

I'll clean the computer when I have the chance since I'm currently at work.

There is no minidump as it was a computer lockup with no blue screen or error message. I do use Windbg to diagnose error before but this time there was no dump to analyze

Did everthing that you listed. Clean my computer and download Core Temp which show my CPU never got above 40 C when it freeze. Ran scandisk and sfc /scannow and nothing was found. The computer lasted the whole night just downloading torrent.

I tried to switch out my 2 stick of RAM with different slot and also having just 1 stick inserted but problem persists.

No errors reflected in Event Viewer...that might provide clues?

FWIW: Downloading torrents...is, IMO, a pretty good way to wind up with an infected system.

No message on Event Viewer or minidump was created when the computer lockup. It would been easier to diagnose the root of the problem if there was any clues.

From the above circumstance, do you know what device is most likely to cause the lockup? When it lockup, the mouse always is still functional though windows won't respond to the clicks. And from the lockup while I play games, the game would continue to work w/o sound until there is loading in between.

Not all lockups...relate to hardware devices.

Since the system has supplied no info indicating that it is a hardware situation...I think it's logical to proceed on the premise that it is not hardware. Or at least test the hardware which can be easily tested and which would not necessarily generate an error message.

That means the hard drive and the RAM.

How much space allocated to C:? How much free space on C:?

I suggest that you visit the websites of your respective hard drive manufacturers...and download/run the appropriate hard drive diagnostic utilities. following respective instructions for doing so. If there is a long/extended test and a short term to choose from...run the long/extended hard drive diagnostic.

Hard Drive Installation and Diagnostic Tools - http://www.bleepingcomputer.com/forums/t/28744/hard-drive-installation-and-diagnostic-tools/

To check your RAM, I suggest running Memtest86+ for a minimum of an hour, although I would run it one full pass of tests. Last time I did that on a system, it took about 2 hrs 15 min.

Icrontic Diagnose with Memtest86+ - http://icrontic.com/articles/diagnose_with_memtest86

MemTest Manual - http://hcidesign.com/memtest/manual.html Somewhat outdated, but still useful.

I'm pretty sure its malware, because radio audio clips start playing now at random times.

I just disabled my onboard sound card and so far no lockup even when I play games with torrent in the background. Hopefully that is the reason as I could easily just get a cheap PCI sound card as replacement.

Thanks for all the help, hopefully when I buy and install the new sound card the crash won't come back
