Hello TCS...........
The red light on the bottom of the mouse is on, but the mouse does no work. (it's all working fine at the moment though)
I don't have another PSU that I can try but
OS is Windows XP PRO
Motherboard & processor is about 8 months old (ASRock K7S8X with a Athlon 2400 thoroughbred )
If you think unplugging the MB is worth a shot I will open the thing up and have a go. (what will this do ?)
Regards
FBW
