Hmm! Curiosity got the better of me and I decided to run the windows diagnostic tool (didn't know I had one on my PC, thanks for that vanman). It took approx 8 mins, and the result was that there were
no problems.
Eh? So what was making my PC act so erratically this morning?, everything seems OK now as far as I can tell. Sorry if I wasted your time folks, thanks ever so for all your help.
