Get a good antivirus such as AVG free edition from the Grisoft site, update it regularly and run a complete sweep.

I don't think it's because of Virus, because when i go to safe mode the computer is normal, beside that if i change the computer with higher CPU speed (before was PIII 800MHZ then i changed with PIII 1.2GHz CPU) the computer become normal.
I put the PIII 800 processor to other computer and there is no problem.

When you boot into safe mode most drivers, software, protocols are disabled, since save mode boots with limited services.

If it were me, I'd start with a webscan of the system

If that comes up with nothing it's time to start swapping hardware.

Hopefully you have access to componets you can test with

Good Luck
