Recently my GPU drivers have started crashing whenever I play a game. My PC is fine in windows and when running other programs and such but as soon as I start playing a game the screen will flash black after a few minutes and most games will crash giving different errors depending on the game. Usually it has something to do with the GPU drivers not responding and restarting.
It started when I got Mad Max; I would play for less than 5 minutes before the game crashed. I then opened my case and found that my GPU was really full of dust leading me to believe it was a heat issue. I cleaned it out properly and sure enough I was able to play Mad Max for more than 30 hours without any issues, and all my other games worked fine as well. Then about 2 or 3 weeks ago I got a new mobo, CPU and RAM and since installing them I have been having non-stop issues playing games on my PC. I've tried a whole bunch of different drivers but the problems persist regardless. I used GPU Z to check what temperatures my card reaches and the highest it goes is about 80 degrees, which should still be fine as far as I know. No matter what game I play, it only lasts a few minutes before my screen flashes black and the game either continues or crashes. If it does continue the black screen crashes start happening more frequently and it makes playing pretty impossible.
As a last resort I installed MSI Afterburner and downclocked the GPU and boosted the GPU fan and that seems to work, although it really is not an ideal solution. As far as I can tell either my GPU is busy dying (or just needs better cooling/new thermal paste) or my power supply is not supplying enough juice for everything. I don't have a spare power supply to test it out properly and I'm scared if I decide to buy another GPU my issues will persist because the problem is not the GPU.
My specs are as follows:
i7 920 @ 2.67GHz
6GB Triple Channel RAM
Geforce GTX550TI
My PSU is 600W if I'm not mistaken
Anybody have any (other) ideas as to what could be causing my issues?
