windows in XP shake rapidly when opened (maximized)

[Waiakead2]

I have a laptop running XP Pro. I suspect that there is a virus/spyware that has gotten passed me in my hunt to fix this problem. I have installed Trend Micro anti-virus the latest version and run several scans, ran HJT and fixed what I thought to be appropriate issues, and ran a free version of AVG anti-spyware and rid the system of them. After all that any windwo that I open up will start to shake rapidly like its trying to maximize but cant do it successful.

BTW the shaking also occurs in safe mode.

Any suggestions?

Go through the steps listed here.

Sounds like a video card problem to me, but without seeing any logs or an example of the problem, it's difficult to say for sure.
