Mouse and keyboard stop working? -- fixed

[pixisticks]

Okay, I have an HP Pavilion desktop that runs Windows XP. A couple days ago, everything was working fine, but I had to unplug and move everything so I could build my new computer desk. When I plugged it back in, I thought everything was okay, but I mostly use my laptop so I didn't use it much.

Today, I went on my desktop to get some pictures for a friend. I wanted to make a .zip file for her, so I did the 'right-click, new, compressed folder', etc. etc.. When I went to go type in the name of the folder, nothing happened, and I realized my mouse wasn't working. I had to press and hold the power button on my computer to turn it off and restart. I did it a couple more times, and I realized that any time I pressed a button on the keyboard, even something like num lock, the mouse stopped working. The cursor would still be there, but I couldn't move it or click or anything. I don't think the keyboard worked at all, but I can't understand why it's freezing my mouse too. The rest of the computer seems to work (I started the internet, pressed a key on the keyboard, and the mouse stopped working, but the internet page still loaded). I also switched out the keyboard for a different one, but when I started up the computer on that one, it couldn't get past the start-up screen.

Can somebody help me? It's a pretty old computer (I got it about seven or eight years ago) but it got a new hard drive about two years ago, and everything was working fine a couple of days ago. I know my grandma blew a fuse yesterday with a lamp, but it wasn't plugged in, so that shouldn't have affected it. Help! I'll provide whatever other information I can, but I can't really search for anything on my computer. 

FIXED THROUGH SYSTEM RESTORE. Thank you, mom.

Are the mouse and keyboard USB and if so are they connected to a MOBO USB port (legacy) or to an accessory USB card?

I had this issue with an E machine. If there was a hard shutdown the USB accessory card was not recognized on boot up but the PS-2 keyboard and mouse ports worked.

If I used the PS2 ports and rebooted, checked driver issues through device manager and repaired or updated them, then the USB ports would activate again.

Are you sure the mouse and keyboard are in the proper ports......you may have mixed them when moving the machine....what does device manager give you?

No, both my keyboard and my mouse are Ps2 ports. I've noticed that I can get into safe mode and that the F1, F5, etc. keys work when the computer is starting up, but none of the other keys do. And neither the mouse nor the keyboard work in safe mode, either.

Yes, I'm sure--I just checked that a minute ago, just in case. What do you mean about device manager?

I did a system restore (apparently there was a software update today?) and returned it to before the update, and now things are working. So I'll read through that and see if I can find what happened. Thank you!
