I own a Radeon X800 card that had worked ok until Wednesday. I tried to play several games with Windows XP SP3 and Steam and suddenly the screen appeared corrupted. I tried different resolutions but the problem persisted. I uninstalled the drivers and installed them again with no success. Yesterday I installed Windows 7 SP1 in the same machine and the problem persisted. I found out if I choose 16 bit color the screen is ok, but when I switch to 32 bit color, the problem comes back in exactly the same way.
I haven't overclock the graphics card and I use the latest drivers available in AMD site. Anyone could help me, please?
