PCI USB Card problems

Ok, here is the breakdown..

My parents recently moved their PC from one end of the room to the other, doing so they removed all the cables from the back of the computer. Well, they had a printer plugged into one of the 2 USB on-board ports. When they removed it, they broke off part of the inside of the port, I had to use an awl to remove the piece of broken plastic from the USB cable end. Anywho...they ultimately destroyed the port connection to the board. I plugged the printer into the other available USB port to test, no go. I also plugged in a USB mouse, no go. So I bought a Belkin PCI USB adaptor card. I installed the card tonite, restarted the PC, booted up, windows recognized and installed the drivers, then continued to the desktop, but froze before all the icons and taskbar could load. I booted into safe mode, removed all USB components, and restarted, same deal, freezing when the desktop appears. This happened 7+ times. Any clues to help???

System Specs:

Compaq Presario 7594
Celeron 566Mhz
64MB Ram
10GB HDD
Win 98se
Belkin USB 1.1 PCI Adaptor card 2 Port (Attempting to install)

TIA for any help!!! :)

Have you checked the board where the original usb connector is attached to see if there is any damage there?..also, consider shutting the usb support off in the bios..this shouldn't affect the add-on card. Maybe there is a short in the onboard connector

did you go mid-evil on it's a$$????
i would agree with the above...damage to the mobo...

Yes, I have checked the BIOS, but their is not an option to turn off the onboard USB ports. I am suspecting damage to the MB since any USB device I plugged into the ports do not get recognized or work..........

You might be able to unsolder the connections where the usb piece is attached..would probably be better than the way it is now

Disable the on board usb in device manager.
