Windows 7 BSOD, Freezes, etc.

[Talyn]

I have lots of History w/ BSOD before like IRQL NOT LESS OR EQUAL. They seem to have gone away after lots of diagnostics and such. Now the computer on bootup does not start, it shows a quick flash of a blue screen or shows this bsod http://i.imgur.com/82h6v.jpg, then boots up again. I start system restore, the computer works fine then I get the same problem again on bootup or waking up from sleep (sometimes.)

Here's some Info.

First occt test said CPU too hot, so we went inside the computer and cleaned up lots of the dust. 2nd occt test was completed without error.

Note: When computer was turned off to dust when it boot again no bsod's!

Thanks alot, any more suggestions? View attachment 15971

How long did you run occt for? I normally let it run for a couple of hours. From what you've said you've been suffering from high temps due to dust. If you have anymore issues though don't hesitate in getting back to us.
