A few days ago I opened my computer to look at the hard drive. This is a Dell Dimension 5100C running Windows XP Professional. So I found the hard drive and did what I had to do, but when I turned my computer back on the mouse and keyboard did not work. I tried plugging them in to different ports, but there was no response. I tried restarting, but nothing happened, and since I can't use the mouse there is really nothing else I can do. I know the mouse works because I have tried it in other computers. Both the mouse and keyboard are wireless. Please help me figure out what could have happened to my computer, since as far as I know I haven't done anything to the inside.

Make sure you didn't dislodge the USB cables to the mobo. Even if they look OK, unplug them and replug them. Make sure they're seated well.

Plug in a USB keyboard (not wireless) to check your BIOS and OS. You may need to try each USB port until you find one that works.

Going on the premise that something inside the case got dislodged... perhaps CMOS battery isn't holding the settings or some such thing.

I've seen a few stupid systems that come with USB keyboards and mice but you have to enable legacy USB support in the BIOS before they'll work. In this case your USB keyboard and mouse would have come with PS2 adapters.

Of course, if there's no PS2 adapters on your system then I would hope that Dell would not have given you the mbd that requires these... but I've seen it happen before.
