Computer Crashing/Freezing While Gaming

[TheCajanator]

I have recently been running into an issue with my pc where it will freeze/crash a while after starting to play any game. My system is 1 and 1/2 years old and this has never happened before and it only happens while gaming. I have monitored the gpu temp while gaming and it never reaches above 70 (64-65 at max).

What model motherboard do you have? How long into playing the game does this happen, and is it with every game? Have you uninstalled, downloaded the newest drivers directly from AMD's website and done a clean install?

My motherboard is an asus m5a78l LE. The timing seems mainly random although it never lasts longer than an hour and yes i have had it happen on basically all games. I recently installed the newest drivers because i thought that may be the issue but it didnt help.
And by a clean install do you mean windows or the drivers.

Is the crashing becoming for frequent? Does it come when your doing heavy duty gaming or just randomly if your just moving around in town?

The crashes dont seem to be becoming more frequent and the intensity of on screen actions seems to have no impact.

Hmm, I was thinking power supply, but it could be the newer driver is causing the issue perhaps going back to a earlier version may solve your problem.

This is odd, I have just come off a good 2hr session of a game that was previously crashing me, it was fine. I did some general de-dusting and ran my GPU fan at a higher rate and it was ok. Will continue to test tommorow.
