Can't recognize PS/2 and USB at same time




My friend is having a problem with his Gateway GM5072 WinXP MCE that
he fired up after having sat in his basement for years. The PC is
undamaged and has never been used, but he cannot find the original CDs
for it. The computer fired up OK but it wouldn't recognize any USB
devices although the Device Manager shows all USB controllers, hubs
and devices as working. The USB ports work for drawing power to the
USB speakers. I've done all the following while trying to help.

1.) Checked the BIOS for USB enabling
2.) Uninstalled/Reinstalled USB controllers/hubs/devices entries in
Device Manager
3.) Reinstalled chipset drivers
4.) Unplugged computer for 15 minutes (during which time I looked
inside the PC to check for damage or misconnections)

After that last step I of course had to plug in all peripherals again.
When the PC rebooted it actually started recognizing USB devices.
Unfortunately, it no longer recognized the PS/2 keyboard and PS/2
mouse.

I unplugged the PC for 5 minutes without unplugging the monitor,
modem, speakers, and PS/2 devices. I removed all USB devices.

After rebooting, the PS/2 devices worked again but the USB devices
were again not recognized. We'd like to get the system working as is
before trying to reinstall the OS or install a USB expansion card. Can
someone give us more ideas as to what's wrong with the system? Thanks.
