Am having a P4 system of 1.4Ghz speed. The problem is that my PS2 keyboard is not detected in this system. When I reboots the system the keyboard lights will blink but later it is not working on this system. I had checked this keayboard in my friends system and its working finely. So what might be the problem???

Check your bios settings. Some have an option for usb/ps2 keyboard. – MrStatic Dec 21 '09 at 18:30
Even for entering into bios also i have to use keyboard. Where here is the main problem is of keyboard. – hari Dec 21 '09 at 18:38

Try another known-to-be-working ps/2 keyboard with the system.

If that doesn't work, then try a known-to-be-working USB keyboard with the system.
