I have a HP desktop computer and the tower won,t come on at all, the monitor comes on ok.What can I do? I have checked all the cables and the fuses externally.

Many Thanks

Thanx I will try and change that then.

Chances are that if there is nothing when you press the button on your tower then more than likely it's going to be the PSU, Power Supply Unit that you need to replace. I had the same problem a couple of months back and since i changed it, it powered up fine and i've had no problems ever since.
