usb ports

[cletus]

Hi, there is probably some really easy solution to this but I'm a bit of a dunce. I have recently had to format my pc and reinstall the o/s (xp) and now none of the usb ports on my pc seem to work. I have checked in the device manager and the usb ports do not even appear there. I am assuming that it is some sort of issue with the drivers for the usb. Any help with this would be appreciated.

Sounds as if you haven't installed the drivers for your motherboard, these should also include the driver for the USB controller, IDE/RAID controller and the AGP bus amonst other things.

I suggest you find the driver disk for your motherboard or visit the manufacturer's website to download the drivers.
