Here is my issue...
My computer is about 2 years old got it because it was supposed to be awesome for gaming. For the past month now its just been randomly shutting down....or i should say it is randomly shutting off, completely. No warning no shut down procedure just straight to the always scarey blue screen of death. All thats left on is the power button light on the front of the tower, no green power light on the back of the case. Ive taken it up with verizon since i have their security suite and according to them it is not spyware or a virus. At first I thought it was over heating so i cracked the case and gave a little help with a regular household fan on a low setting giving it a bit more air flow, but even with that i figure couldnt be overheating because at times it will shut down minutes after powerup.Could it really just be that it needs a good cleaning physically? Or am I going to have to shell out money for a new power supply? How can I diagnose the power supply of that is the issue? Ive rolled it back to a restore point and so far its run ok for ten minutes. Any ideas? What could be the problem? Hardware, software, spyware? Any help is seriously appreciated.

Well, clearly, one of the steps here is to clean out all the dust, expecially in the processor and video card heatsinks. Also, while you're in there, reseat ALL the cables, expansion cards, etc.

Next, I'd give it a memory test, at least a couple of hours on one of these. Any failures are a problem, these should run error-free for as long as you let them run.

Could be a number of things...
is there an error code on the Blue screen of death?
if so what is it?

could be drivers, unseated connection, registry problem..many things
