The mouse and KB work OK on USB ports. If I plug anything else (data stick, external drive) in to one of the other USB ports
the machine freezes. If Windows 7 is running the mouse won't move, the clock stops, etc. If I plug in a data stick before booting
it just gets started on the the progress bar and then freezes. In both cases I have to power down manually. I tried adding a Belkin
PCI 5 port USB card - same result. I've tried removing cmos battery, upgrading BIOS - no help. I have to suspect the MB but why
do mouse and KB still work ?
Any ideas ?
