I used to have an ATI radeon 9000 driver.
When I tried to update it, the AIT update software said it couldn't and I should have a VGA driver installed first.
I tried to get Win XP to do that, but there is a problem and it did not install correctly, leaving a yellow mark in device manager. I even uninstalled the VGA driver and rebooted. Same problem. I also tried to restrore my system to an earlier date, but WinXP refused to do so.
What can I do? My video works so slowly now!
Thanks!
Open WindowsUpdates website and run WindowsUpdates.
Check your HD for errors (run chkdsk command).
Run a registry cleaner.
Run command sfc /scannow.
Virus, trojan, spywares, malware?
How about doing a repair installation of your Windows?
