100 cpu usage even system idle process uses 70

I just installed Vista on my machine. It's not the latest and greatest computer, but it should be good enough to run Vista decently...yet it doesn't.
Specs are:
P4 2.4Ghz 1GB RAM GeForce 6200 video card Only Vista installed, nothing else.
When it loads up, the mouse constantly skips across the screen because of the 100% CPU usage. I practically disabled every service that was started and still no improvement. Disabled the soundcard and linksys wireless network card because Vista couldn't find any default drivers for them. Still 100% CPU usage.
Shut it down, and kept moving the mouse to see if the cursor would move smoothly as services were shut down, but it continued to skip all the way up to the point when the power went off.
Booted up in safe mode, and everything ran smoothly. I super stumped and don't really know what to check next. Any suggestions?
Thanks

Ok, I finally got it fixed!
It was my video driver. Apparently, the microsoft drivers for my 6200 was buggy, and Nvidia has new drivers for Vista. Installed that and now everything is running smoothly!
