Either a failed video card or a driver issue. Since no one takes drivers from Windows Update I fear it's a machine in need of repairs.
About System Restore your post is unclear. That is, many write such because they have Norton or Kapersky and didn't perform that extra step to use System Restore. I don't write what step that is because it's a shame that such suites interfere with the OS.
I can't get my XPS 630i to boot up. after the initial Windows start up screen I get this screen on my monitor and it never opens to Windows where you log in. I run XP on this machine and this just started after I broke down and did a Windows Update. I'm thinking I should just delete the recent updates in the Control Panel ADD REMOVE Programs option.
I've tried setting the boot options to default, and used the OS disk to boot up. I'm also not able to use any of my restore points! Now I have to boot up in safe mode to even see a desktop.
Any other ideas?
