Right, so seeing as this forum has been so damn efficient at sorting out previous problems, here's the latest tale of computer woe...
A while back I bought a refurbished PC with Windows 7 pre-installed. For about two weeks all was good, and then it began: The mouse kept freezing intermittently. It makes that noise like you've disconnected it and reconnected. If you have device manager open while it's doing it, the list of devices keeps refreshing, just like it's found a new device.
The problem will either go away after a while, or remain until you get so frustrated you turn the PC off, or it will stop functioning entirely and a little pop-up box will say that a USB device has malfuncioned. You then have to physically reconnect it. Whereupon it may or may not present with the same problem. The annoying thing is that it's so random I can't track down the problem.
At first I tried using an PS2 adaptor, same problem. Then I thought the mouse could be buggered, so tested it in another computer and it's fine. I then borrowed another mouse from a mate just to be sure. At first I thought I'd cracked it as all was good for a couple of days, but then, alas, it all started again.
So like I say, it seems to be almost random. At the moment it's fine, happens once every now and then. But earlier it was going crazy, like I was connecting and disconnecting it furiously
No other problems apart from this. Needless to say it's maddeningly frustrating.
