Thanks Keith,
I'll try memtest first, complete reinstall as last resort.
If the problem doesn't happen too often I can sort of live with it, at least for a while. I just wondered whether it was a known problem.
Come to think of it, it could also be a motherboard problem. One of my front USB ports has stopped working, and the mouse is USB (plugged in at the back). I'll dig out a PS2 mouse or a PS2/USB adapter and try that route...
