hello hope some one here might be able to come up with a few sugestions. was called out to friends son's pc as he said his mouse not working, got round there and tried new batteries nothing (its cordless usb)ok try keyboard nothing, change batteries in that, nothing. so get my spare keyboard and mouse P/S2 type and plug them in turn pc on still nothing, get no bios errors about missing keyboard or mouse. try to enter bios nothing keyboard / mouse still not working.turn off reset bios to default by moving jumper and then reboot, get bios checksum error press DEL to enter bios or F1 to continue but can't as keyboard still not working. reboot and try the usb keyboard and mouse again same problem. am stuck now any suggestions. when usb mouse plugged in there is no optical light on the underside of mouse.the only other thing to mention is that he was trying to install a cheap creative web cam and as usual didn't bother to read the manual so he plugged in the webcam before installing drivers,even though there was a big bold warning on webcam and onthe instructions that you must install drivers 1st, but i cant beleive that this would have taken out the P/S2 ports. the motherboard is an MSI socket A sorry forgot the model no.

Try a reset to BIOS to Defaults.

By either using the clear CMOS jumper if fitted

or remove CMOS battery fror a few minutes and then replace.

Reboot and see what happens.

keyboard works in the BIOS then it is obvioulsy a Windows thing.

Do any of the KB and mice work in safe mode?

i had this with an old Packard Bell iConnect 1350 made in 2000, i had to get a BIOS flash from PB's site to enable USB keyboard support as there was issues... It was also an MSI 6340 mobo...

check MSI's site archive for support:

Just double check that when trying the PS/2 items, you have them plugged into te correct sockets (even try changing them over in any case).

Seen this many, many times to be the cause of a problem that started out as something different.

Also - it is possible (though rare) to damage the PS/2 ports by pluging/unplugging with the power on.
