hello
one night I left my computer on for downloading something overnight , after I woke up I saw my screen was divided to half ,one half was darker than other one , so I restarted my pc and problem solved, I have a problem with farcry 4 too ,some times vertical rainbow lines appear in one frame of the game ,it may be game's problem (I don't know).I tried to update my graphic card driver ,I uninstalled it by ddu first then downloaded new driver and started installation , screen went black and came back during installation several times , I know it is normal but in one or 2 of the black screens vertical rainbow lines appeared ,after installation I restarted my pc to complete installation ,
after computer booted up , in the lock screen , screen went black for 2 seconds then came back. I
thought my problem solved but yesterday after I turned on my pc I got a screen full of vertical colorful lines .so I restarted my computer 2 times but the screen did not change , finally I turned off my monitor and after I turned it on again I was in lock screen, then I ran
furmark stress test for 15 minutes 2 times and nothing went wrong ,I am playing bf1 without problem too , but I will not be surprised if the problem comes back , I really want to know it is graphic card failure or monitor failure.
my system spec:
i7 6700k
msi z170a gaming m5
gskill tridentz 16gb 3200 MHz (8*2 gb)
asus gtx 1080 ti founders edition in sli
1235 watt power supply
