Dell XPS 400 desktop, XP...5 rear, 2 front USB ports.
So, after a few days off I decided to log on to the desktop and start playing. First hand pops up and my mouse stops working, then keyboard. Anway, I have one port that's working now, when all appeared fine before (using 4-5 at one time).
I'm going to get a USB PCI card later today (would get a hub, but it'd really suck if the last one stops working), but I was just curious if any knows what would cause this or if there's anything I can try to fix the problem.
