About a month and a half ago i started have trouble with my pc. When I would play the screen would get these tiny lines verticaly accross the screen. If i tried to countinue what i was doing it would get worse until you coulnt see what you were doing. I had an ati radeon 9500 pro and it was to weak so i decided i could use this as an excuse to get a new card. I got the ati all-in-wonder x800 xt installed it by the book and and the same thing happened only worse. I tried reinstalling the drivers many times, made sure all fans were spinning, Updated the bios on my motherboard, swithced the screen and tried the card in another pc where it worked flawlessly. Those didnt work then the next day it just started to work and didnt mess up for a full month until yesterday. I shut down my computer for an extended period rather than just a restart, which is what i think caused the problems to resurface. It always randomly happens to. It may happen on start up or it may happen 5-10 min after the desktop has already loaded. But it will always happen within 15 min. I can still here the sound if i was doing something though. The psu tends to act up now also. This is what it looks like: on loading screen on the desktop The desktop pic should be brighter. The lines are white.
