Not sure if this is actually hardware related at all.
I have a fairly new PC (month or so old) which runs on Windows XP. I use wireless keyboard and wireless mouse.
Today I had to hard reboot my machine as it locked up completely whilst running a game.
Now whenever I try to log in everything seems to work ok (inc the wireless keyboard) but the mouse just wont work. I cant move the cursor at all. I have tried logging in, in safe mode and the same thing happens. I have tried the mouse via usb and via the "usual" mouse socket. I have tried a different mouse. I am stuck!
Any ideas?
