My daughter has an HP pavillon desktop a1600n. She turned her computer on and received a blank screen with the following message: windowsroot>/system32/ntoskrnl.exe. I ordered the recovery disks from HP and installed and rebooted and received the same message. I contacted HP again and they instructed me to wipe the hard drive, which I did and reinstalled the recovery and rebooted and the same error came back. I noticed the mouse port does not work. I have to use a mouse with a USB. I tried several different mice and none of them worked. I do not know if this failure has caused the problem. The computer did not come with a XP disk. I tried to copy the needed file from my computer and I received an error message. Where do I go from here? Do I install a new hard drive? Do I install a new operating system? Depending on the cost, would I be better off buying a new computer. I am not worried about any files. There was nothing on there but pictures.

Check in the BIOS setup, as some have an option to enable or disable PS/2 mouse, and
it may have turned off.

Another possibility is that the PS/2 port has died. This can happen from an
electrical surge, most often happens from unplugging and re-plugging the PS/2 mouse
while the computer is ON. What usually happens is the tiny fuse on the motherboard
behind the PS/2 port will burn out. Unfortunately, it is soldered to the
motherboard, making its replacement not something for a do-it-yourselfer or even for
the average computer tech.


I have seen this occur a few times with a keyboard port, but not yet with a mouse
port. does your keyboard work in the other port?

The keyboard does work. She mentioned that the mouse did not work and I bought her a wireless. I did not connect the two at the time. She does not use the wireless, but uses the mouse my son had for gaming which connects to the computer via a USB. The problem with the mouse occured about 4-6 months ago. The computer problem happened two weeks ago.

you can try this.....HKEY_LOCAL_MACHINE/SYSTEM/ControlSet001/Services/i8042prt (group keyboard port) delete the entry. windows will rewrite the entry
