Ive recently been encountering this problem, All was good for a few months when a I built this system, and now for some reason every 3rd or so boot up of my PC My display drivers stop working.
Device Manager says under both my Graphics cards: "Windows has stopped this device because it has reported problems. (Code 43)"
These graphics cards are in SLI
I have a monitor connected to the top card via HDMI cable
I tried updating my drivers to the latest version, and all was ok untill I restarted my PC a few times, a few restarts later it has done the same thing again
What could be the problem? All was fine untill now
My current build is:
CPU : Intel Core i7-950
M/Board : Gigabyte X58A-UD3R
RAM: Kingston Hyper X DDR3 RAM 2000mhz
Video Cards: GTX480 x 2 SLI
Case: CoolerMaster HAF 922
PSU : Antec 1000watts
