There doesn't seem to be any problems with the surge protector so I can now rule that out. I also tried the computer back into the ext that worked first thing yesterday, that no longer works. It is definitely looking more like the computer is at fault and not the anything to do with the power.
If I want to go into the bios I have to sit and wait for about 5 min before I can press delete.
I have phoned them again and this time I will be without the computer for a week because they said it worked fine for them once they changed the memory. Now I am getting mad. No computer for a week
