Is this a desktop or laptop?
If you open a program thru Start, programs (select program) does it work normally the first time you open a program?
Just for grins, try a different keyboard if its a desktop.
I am thinking, maybe you should do a hard drive scan and let the scan try to fix bad sectors.
Then maybe run SFC scannow google that for directions.
