ATI Radeon 9500pro 128Mo random reset to 640*480 4 bits bug ??? ...

Hello everyone,


Very randomly, my computer hangs under Windows XP sp1, keyboard and mouse
unusable, but processes and downloads still running. After 2 minutes, the
screen goes black, then an Error Message appears: "Windows has repaired a
faulty device", and the screen is set to 640*480 4bits. I have to reboot my
computer to get back to normal 1024*768 32bits, except I have to change
manually the refresh rate from 60 to 85 hertz.

Anyone experiences the same problem? Any advice to sove or prevent this?

Thanx in advance.


M.

I had the same problem two weeks ago...

I took the card out of my system, cleaned it and put it back in. Then a
fresh driver install and all the problems were gone. Good luck,
