Well, this miserable saga continues to give me grief. It was perfectly fine first this morning before I went to work. Normally I'm not away too long so I leave my computer switched on. However, today, Mrs Clive is away and knowing that I would not be back myself until this afternoon, I took the precaution of switching my machine off. When I rebooted after I returned, and began to enter in all the data of today's work, the display started to break up again and very quickly froze up. It didn't automatically reboot as I've disabled that facility, so I had to switch it off at the mains.
Ket, I don't really understand what you mean by "CAUSE: This behavior occurs because a driver or other problem damaged the input/output (I/O) driver structures." Does that mean that a driver has damaged some hardware? I've taken a screen shot of the event log for you to see.
