Right just had a go with a more hungry keyboard and nope no dice so I think the PSU has gone out (wasn't a great one, just one of ebay) 

I will order one and have a go, and then I will know whether or not it really is the PSU. Shook the PSU and sounded like something was lose so maybe I should spend and bit more and get a better quality one. Thanks for responses, if I don't have any luck I will post another message and hopefully we can figure this one out.

Cheers guys,

Dave
