    WinXP Home SP2, Generic 'No Name' laptop Model A928, SiS Chipset (I hate SiS chipsets!). Here's the deal. This laptop had a totally corrupt Windows, so I backed up the docs, pics, etc, formatted the HD, reloaded WinXP Home without incident. Finding drivers was a bit tricky 'cuz of the generic no name thing. Anyway I finally found the drivers: audio installed OK, LAN is OK, modem is OK, and the video driver (SiS 650) installed OK too. But upon rebooting, Windows loads normally, then as soon as the video driver kicks in during the scrolling blue progress bar, the screen blanks out and comes back as just a sea of different shades of blue and purple, and it slowly fades from one color to another, with dark spots here and there. So I plugged in a regular CRT and it works perfectly!!! The refresh is locked at 60htz and changing resolution doesn't do anything. The thing is, the display was fine before the wipe and reload. The new drivers all installed w/o a hitch and (like I said) an external monitor works 100% perfect! Any ideas??? HELP!!!!

    What version drivers did you use? Are they the newest?
    Sometimes older drivers work better.

    Disable the video card in Dev manager. If it looks ok on reboot, its the video driver.

    Thanx for the tips and help, but the problem has been solved. It was weird: when the video drivers kicked in, the laptop LCD looked alot like the 'Dremples' screen saver. If you've seen it, you know what I mean ;) Anyway- I forgot that SiS has an additional AGP driver that works "hand-in-hand" with the VGA driver; sometimes it's needed, sometimes not. Usually it's only required when using a desktop PC and you add an AGP card. Installing the SiS AGP driver first, then re-installing the VGA driver solved the problem.
