on boot up my keyboard ask for password but when I type it in it only beeps or clicks inside computer I cannot enter a single letter the keyboard works on other computer I can't hit f8 0r f2 or f12 nothing works
does it boot up into windows or is it a BIOS password its asking for? If it's a BIOS password you should be able to find the motherboard manual which will reveal the BIOS password reset procedure.
