Dilwyn, If there was a thunderstorm then it's possible that you have a corrupt drive and or RAM.
Given the symptoms you see I bet avg is corrupted. Have you been able to run a full chkdsk in safe mode after start up. Get hold of a mem tester too. Linux works. I don't know anyone these days with the problems you describe but regardless try a live dvd to test it out. You never know! But obviously not now, although a Linux live system might help find the problem, strangely enough. Good luck. Cheers, Norm -- Sent from my Android device with K-9 Mail.
