Hi Yesterday evening, my mouse and keyboard started to be non responsive. I would be in the middle of writing a sentence, but all of a sudden my keyboard and mouse would stop working, then about 10 seconds later start up again. It wasn't a total system freeze, because chat messages would still appear on MSN, and everything would still move about on screen when i was playing a game. This happened on and off for about 1 hour, until I couldn't get the keyboard or mouse to work at all. I booted my PC this morning, but my keyboard and mouse still failed to work. It would boot into Vista and XP fine (im dual booting), but they still wouldn't work - even before i could get into Windows. I reset cmos, I tried switching out the RAM but nothing seems to work, and the problem seems to be getting worse. About 5 mins ago, I tried to boot into XP, but my whole system froze, and my motherboard let out a faint single beep. When I boot up, I get a single beep telling me that all (should be) fine. Anyone ever had this problem? or anyone know how to fix it? (Btw, I have tried different keyboards and mice, and I've tried plugging the USB ones in different sockets, but it didn't make a difference.) Thanks FAXA.
