My specs are
Motherboard:MSI Z97 PC mate
CPU:I3-4150
GPU:R9-270x
HDD:1TB drive
PSU:EVGA 500w 80+ bronze
Ram:2x8 A-Data
I've had all of the parts for 11 months except for the HDD. The other day I came home and my jumped on Rainbow Six and the screen became one dim color with multiple white vertical lines but I could still hear sound going on in game and I had to restart my PC.
I tried other games like BFBC2 but the same problem arises.
After a few tries My PC won't even get past The splash screen, My GPU fans are spinning and it feels at a cool temperature but there are two vertical strips of artifacting visible. I tried logging into safe mode but that crashed as well. My PC runs just fine when my GPU is not connected via PCIE.
Hopefully that helps and sorry for the late response.
