keyboard and mouse lock up after the pc boots. But you can enter setup using the keyboard.
Itried in safe mode still they are locked up. this is driving me nuts. what should i do to over come the problem.
The pc is using windows xp service pack 2. Is a dell optiplex 755 intel(R) duo core 1.8 GHz @ with a Ram of 512.
thanks
