Hardware problem...?

[Hicks12]

Well for the past few days i seem to be having a couple of problems, my computer will randomly die. First time this happened it was a Bluescreen regarding a graphics driver, this is my first BSOD since ive had Windows 7 (as soon as beta was out..). Next day it just randomly froze and had to turn it off.

Now again its happened, but this time the screen displayed loads of grey lines kinda like when your setting up your display or what tv chanels used to look like when they were down. Im going to assume its my gpu? If so what is the possible cause of this random dieing.

It happens randomly, so far no problems have happened within an hour but this one was the earlier at about 3 hours. It happened while i was using Firefox (last time it happened while alt tabbing back into age of empires 3).

ANy help appreciated .

Does the error look anything like this from one of my many cry-for-help threads? The mixture or bluescreens, freezes and jumbly nonsense sounds familiar...
