Good day gentlemen.

Apparently some of you were unhappy with the brevity of my response last night. Sorry, But I was as drunk as a lord, and could barely type.

My reasoning behind advising a p/s change, is that around 4 years ago, we sold around 300 'puters to a local government department. We began receiving calls frequently regarding machines that wouldn't boot. I soon noticed that each of the troublesome machines had printers attached. When powered on, they would not responding and I could hear a low humming noise coming from the P/S. Remove the printer, and it worked fine. Turned out to be a glitch in a batch of P/S the manufacturer used.

PCSolutions, this may not solve your problem, but it was the one thing that popped into my sotted head
