Hi All, Thank you for some really good ideas of what might be wrong. I did go to the control panel & from what I could see it says that it's working although I'm not really tech savvy so it's possible I didn't cover all bases with that. Briefly the keyboard wouldn't work but it's working again. The mouse is still being weird. I wonder if I might need to buy a new mouse?? I will try the unplug it for a few minutes suggestion next (Do I unplug it with the computer on or off?) The computer is a desk model (not a laptop) & the model is Compaq Presario CQ5300Y-PC, the mouse is also a Compaq, I'm not sure what the model number of it is as there are different numbers on it...pn, pid, ct, all have numbers following those letters & I don't know what any of that stands for (sorry for being such a dork) I appreciate the helpful suggestions. OMG, it keeps doing the weird sound/light gettin' stuck thing, it's driving me CRAZY!
