Diablo 3 Keeps Crashing

[Amitojc]

I am having a few problems with Diablo 3. When I play it, within a few minutes to a hour the game crashes. I recently changed the video card, but the same thing has been going on. The game just crashes, and it goes back into windows, with an error message. Do any of you know what could be the problem? Is it a power supply problem? Here are the specs of the system. As well the flash and videos on the browser firefox doesnt work as well. It says your visual driver crashed and gives me an error code. When I get it again Ill tell you it.

First of all, test your RAM http://www.memtest.org/

I'm getting quite a few of those 'driver stopped responding' crashes as well (not so much crashes as short freezes before the screen blacks out and the system starts responding again.

I too am playing some D3 with Firefox usually open in the background. The funniest part is that the crashes often occur when the GPU is downclocked (250 or 500 instead of 880 full speed) as the game plays FMV.

I got those as well, resolved the problem by down-clocking my GPU. My 7850 was running at 1200/5500, but this prompted the "display driver has stopped responding" error message. Clocked it down to 1050/5500, and it runs perfectly fine now, no crashes.

Can you get us the error message? Check for it in the Event Viewer Logs as it may be there as well. Also, what OS are you using.
