Vertical Gray lines...appears and computer locks up!

post #1 of 4
Thread Starter 
Vertical gray lines appear during computing causing the system to lock up. Is this because the horizontal video amplifier is defective? Perhaps, is it graphic card related?

It's hard to say based on this single symptom, which could be caused by a number of things. If I had to guess, I would say it's probably related to the graphics card. Do you have another system you can test the 7850 on? If you see the same issue, then it's the culprit. Luckily, Sapphire has excellent customer service. Good luck!

^^ Dud GPU. Had the same thing with my old 6970. Turned out to be a VRAM problem and RMA'd it.
