Hmmm...
I had the same problem, but strictly in XP, after upgrading to a new
motherboard with built-in graphics. I made sure to upgrade the BIOS to the
latest version, and download the latest driver (it was an SIS chipset), all
to no avail -- had the exact same issue as you.
Later, I upgraded the video by adding an add-in board, and the problem
vanished. Up until now, I thought it was a defect in the motherboard's
on-board video circuitry. Given your problem, I'm thinking it may be a
driver glitch (i.i. a programming error).
