Hi guys, I've got an issue with my computer. Since a while now when I watch videos or start a game the screen will freeze, flicker and reset (as in, black screen and then it comes back and everything is normal). For me, this sounds and looks like the graphics driver resetting. I've done some reinstalls of the gpu driver, even changes videocards but it doesn't seem to help. Then for a while everything worked like it was supposed to. I could play games and watch videos again, even though I changed nothing to my setup. Now a couple of days ago it has started again. Random freezes and flickers and resets (in that order) of my screen. My screen even turned off once, as if it didn't get a signal. Is this a gpu related or could it be PSU related? The reason I am leaning towards the latter is that I have changed from a 280X to a GTX560 to a 260X and it keeps happening. They cannot all be faulty (besides, I sold the 280X and didn't receive a complaint so I doubt it was faulty).
