Thanks to the above. I am going to try and count the beeps and go from there. I suspect it could be a video card conflict with motherboard if there are enough beeps. It's what to do if i discover the problem.
I don't think it's the processor as the computer runs well all day with all programmes. Just the thing doesn't turn off or restart.
Thanks to all again. Anymore advise would be welcome. I will ask again probably after trying out the above.
