Keyboard&mouse are working until XP start.

I have a strange issue with a customer`s computer. Keyboard & mouse are working fine until XP start booting. Then the keyboard stop responding while "num lock" LED still lit. The Mouse pointer never appear on the desktop. I am able to go in the bios and modify settings, but cannot boot in command mode or repair mode.

Any idea?

No they are both using PS2. Effectively, it look like drivers problem since it occure during XP boot. However i think it may be caused by hardware (MB) error when the hard drive is starting. This computer use 2 hot swap tray and had hard drive error 2 weeks ago with the other OS. Scan disk never found anything wrong.... then it look like there is something wrong with the motherboard or its HD controlers. This is why i would like to know if someone already seen such symptom whith a defective motherboard or other parts.

Concerning the XP drive, nothing has been installed or removed. It happen since the OS got frozen during a CD burning process. The second drives (Win98) have have also some problem since the obscure disk error. Theses information let me believe that it may not be OS related.

NOTE: other keyboard has been used for testing

try running sfc /scannow from the run box.

I tries yesterday to boot with both keyboard and mouse disconnnected. It boot as if they where there, no halt, no bip. Also tried to connect them one at a time and use other keyboard. The last thing i am able to do is to issue a F8 to go in safe mode and command mode, but curriously it does boot in normal mode anyway!!

tomorow I will try the recommend boot CD, i don't know them, it could be useful. I often use UBCD, but it is always interesting to find better one.

nobus

did you run sfc as i suggested?

No it was not USB device, but PS2 device. It appear that the problem was caused by corrupt OS component. Thanks to evevybody.
