My Compaq Presario laptop's keyboard is not working properly. When I start Windows XP normally, some keys don't work. When I start in Safe Mode, all my keys work properly.
What keys don't work specifically? And do they not work consistently?
You may have a driver issue, maybe and it is using the Windows default driver in safe mode, maybe some keyboard software gone amok, or you may have a virus.

I also had the same problem few days ago, but my problem was resolved when I formatted my computer.
If you don't have many important files on your computer, you could do the same, or scan for viruses as stated above.
