About 1 year ago I built my own computer (Specs I'll Post at Bottom). It has worked fine with a PreBeta build of wincows 7, no errors, nothing has bothered me before. But now, after about an hour of surfing the web + another hour of gaming, it crashes to a STOP error. I figure, meh maybe it was the new updates, but it wouldn't let me go to a restore point without first crashing again! After tons of full, 4 hour reformats, and reinstalls of Xp, Vista, And windows 7, it still does it, it even did it throughout all installations. I'm pretty sure it isn't a hardware failure, but I'm also sure I've had about every possible STOP error there is! Please help me!!!
E8400 3.0GHz
ASUS P5QL PRO
4GB G.Skill RAM 800 MHz
1TB WD Black HD
Radeon 4850HD
Common Mouse, Keyboard and Screen.

Try press F8 when PC powering on and select from the list the "Last Known Good Configuration"

This is only good for system software/driver error.

Hope this helps!

I'm pretty sure it isn't a hardware failure

Sure sounds like a hardware problem to me, possibly a heat related hardware problem. Sadly, you did not post the error message that came with the BSODs - they can give valuable clues.

Is the system clean of heat trapping dust and dirt? Are your temperatures fine?

I would try another power supply just be sure everything else is being fed clean power. Then I would start looking at RAM. And the next time you get a BSOD, don't ignore it. Look it up: STOP Messages.

I agree with Digerati, especially because:

it even did it throughout all installations

Download BlueScreenView
No installation required.
Double click on BlueScreenView.exe file to run the program.
When scanning is done, go Edit>Select All.
Go File>Save Selected Items, and save the report as BSOD.txt.
Open BSOD.txt in Notepad, copy all content, and paste it into your next reply.

Besides the software concern, check the system temp and make sure the CPU and VGA fan are working under spec.

Hope this helps!
