I'm trying to help a friend who is having a problem with his graphics card.
His system is
Windows 7 Ultimate
Core i5, 760
ASUS P7H55M board
ATI Radeon HD 5770 graphics card
4 GB DDR3 Ram
1TB 32MB speed harddrive
the system was built by him.
Been working okay til now, about a month or two... It will be okay for a while when suddenly the graphics card puts lines on the screen or it will go black and the sound will get stuck.
It happens no matter what he is doing.... doing data files, working on pictures, surfing the web..
He's never had another graphics card installed so there are no drivers from any other one. He has the current drivers... (but I think that ATI has a new one out this month he hasn't done yet).
any idea how he can solve this problem. I'm afraid if he tries to return it for another one, he could end up with the same problem if it has something to do with the drivers or something else.
