Screen flashes, taskbar goes to the top, what do I do?

It is a windows screen saver, the one with the 3D pipes.

Just making sure, it's not 3rd party screensaver.

Yea, it's not.  Do you think that having the monitor power settings set to "Turn Off Monitor After 20 Minutes" has anything to do with it?

It shouldn't. Let's try Safe Mode, first.

Ok, last night I put it in Safe Mode, and when I woke up it was fine.  So then before I went to school I put it back to Normal Mode.  When I got home from school I moved the mouse to remove the screen saver, and it was fine, for about a minute and then the screen and mouse just froze, so I had to restart it by holding down the power button ( since Ctrl+Alt+Delete wouldn't work).

Try re-installing both your mouse and keyboard drivers.

And, it is back to the flashing screen.  Today after school it was all messed up like it was a few days ago.

Video card going bad?

Sounds like the same symptoms I had with my win98 once. The screen and mouse would freeze for no apparent reason at any random time. Then one day it froze and I couldn't get it to boot back up to Windows. Turned out to be the vid card.

But when I run my computer in Safe Mode it is fine.  It's just when I run it in normal mode that it messes up.

This is because in Safemode Windows is using a generic driver to run the hardware...therefore it is either a driver issue or the actual card going bad as evilfantasy suggested...

That's it.

Ahh, well I'll just deal with it for a while longer then until I get a new computer. 
Thanks for all of the help!
