To figure out if it's PSU or GPU they swap in new ones. Horrible, isn't it?
Okay, this problem occurred out of nowhere. When I was ingame playing Dota 2 which is not that demanding for the graphic card, the drivers crashed and I couldn't restart the game. I decided to restart the computer and try again but every time i tried to relaunch the game, my computer either froze and I was not able to move anything, forcing me to restart, or the drivers restarted exiting all the applications with an error message complaining about "windows nvidia kernel mode driver crash". I also tried launching different games.
My first fixes were to sweep the computers GPU drivers and install the stable version I got with a CD when i bought the computer. Didn't work. I also changed a value to 8 in the GraphicsDrivers to 8 (A how to fix told me to do it) but that didn't work either.
So now im stuck with 2 different answers to the problem. First one is my GPU is too old and I need a new one. Second is my PSU doesn't provide enough power to the GPU.
Intel(R) Core(TM) i5-2500K CPU @ 3.3GHz
GeForce GTX 560 Ti
Any help that can confirm if it's either PSU or GPU problem or both, would be greatly appreciated. Or if you got any questions or tests you would like me to run, I would appreciate it aswell. Thanks!
