Frozen /unresponsive mice
Okai, a techy one here thats been causing me issues since before Christmas.
I have some computers that all of a sudden don't respond to there mice. They will work one minute then, whilst working even they will just stick and freeze.
Reboot the PC and they are sometimes ok, other times they won't respond and gives the impression the PC has frozen, which it hasn't as the keyboard is fully responsive and if your clever like all us techs are, we can survive without the mouse for a good while to prove the point of "who needs a mouse anyway :D"
I have tried new mice, both of the PS2 and USB Variety, tried a reformat and re-build from scratch, always looks good then within 48hrs it seems to start the issue again and were back as bad as it was before. It seems that the Mouse option in device manager just disappears! and plugging / unplugging a USB mouse makes no difference to it, its just not in the list, and if you do a Scan for new hardware, it seems to lock the PC up 9 times out of 10, but it doesn't often appear.
Now strangely a friends home computer also started doing something very similar before Christmas and has the exact same problems, but they are very different machines.
The fact its a large number of machines in my mind rules out motherboard as its going to be VERY strange for about 30 motherboards to have gone weird in this way all at once, so I'm stuck for ideas!
Has anyone any thoughts?
