Now on my spare Netbook. Main pc is currently inaccessible.
Tonight I repeated your suggestion of uninstalling the usb controllers from the start of the list. I skipped the first two (which I believe from the first attempt we discovered were the mouse and keyboard. And I unplugged my headphones beforehand this time around to see what would happen).
And...
Reached uninstalling the second last on the list and it disabled the mouse. So I had to do a forced switch off.
Switched on after and...
No mouse control or keyboard control --- even after an hour of disk activity.
The disk light is flickering indicating the pc is 'doing something' but... not looking good. Eeek!
What to try if the mouse control does not return???
Forgive my butting in but if this were mine I'd have backup-up my data and done a clean re-install of Windows long ago. It seems from reading through this thread that a lot of good and sensible remedial work has been attempted but this still seems to be an unhappy system. I think the only way to be sure whether this is a hardware or software issue is to do a clean re-install of Windows and PCS supplied drivers and see whether the USB port issues are resolved. If not then it's probably hardware, but if this does resolve the issues you'll have a stable system again onto which you can re-install your user programs and data.
