Last april I built a new PC. Here are the specs: Sapphire R9 280x, FX-8350, 16 GB DDR5, 700 Watt PS, 120 GB SSD.
When playing graphically intense games (BF4, Bioshock: Infinite on ultra settings) I initially experience no problems. However, after playing for around 20-30 minutes, suddenly my screens turn into grey vertical lines and I am no longer able to perform any actions on the computer.
I've replaced the driver (13.12) with the newest Beta driver (14.6) and I opened the chassis and cleaned it all up. I've also checked the temperatures but the computer doesn't go above 70 degrees. None of this has helped.
I'm completely lost on what the problem might be and how I should fix it. Do any of you have any suggestions? They would be greatly appreciated.
P.S. I've been playing with the idea that it might have to do with either my lack of power (700W isn't a lot) or the fact that I somehow screwed up the dual monitor setup (I use displayfusion)
