Thanks for the suggestion, Artrooks.
It sounded like a great idea. I did something similar to fix the tv set a couple of months back and it was an instant fix. But no such luck this time unfortunately. The problem is still there.
I can use pen drives in the usb ports, so it's not that they are faulty.
Nor the two external drives. They're both fine. They are fairly big but not huge and they both work fine on PCs with less power than this one. Thinking usbs, I've just checked usb controllers in Device Manager and there are no yellow question marks or other indication of a problem
The only positive change is that I can see the drives in Devices and Printers now. Not in Explorer, though.
I shall leave the computer switched off all night and maybe tomorrow morning when I plug one in it will behave.
