Here's the problem.
Basically our computer went wrong a few months ago (while i was away), so my dad had to phone the helpline and do a system restore to get it working.
I returned home and noticed that our computer was now running SP1, as opposed to SP2 which it was running initially. I got hold of an SP2 disk and installed it. However now ever since i installled SP2 the USB ports are not working at all.
To help with this question i can provide the following info:
ASUStek computer inc.
Chipset: K8T800 Pro Rev: .00
The funny thing is that when i go to the harware tab it shows USB root hubs to be there, with NO errors.
