I have a 845-series intel board. used to work absolutely fine till two days back. Now, out of the 6, only 1 USB port works - as in, if i connect my usb drive, it will light up - showing that it has got power, but it doesn't show up on my computer as a drive - neither in the device manager.

why???

Your only easy choice is to restore windows. We have never seen USB ports fail on the board series, but sometimes Windows will foul up, particularly if you are using Windows 98 or Windows ME... and a reformat and reinstall fixes it.

Hey..

i'm using win XP... already tried reformatting and installing, no use...
