Hi,
A few months ago my old Dell Dimension 4100 started playing up, at the time I put it down to drawing too much power from the PSU (after i added some USB hardware).
Well i've just moved and now the PC is dead, it wont start up at all. However if i unplug the power cable from the back of the pc to the electrical supply, wait about 5 secs then plug it back in th following happens. First there is a large clunk/thud noise coming from the PSU, if I then try the power button, the front power LED lights up briefly but nothing else happens, no other component start up.
Would this be a fault of the PSU or something else?
I only ask becuase the PSU is a Dell proprity one and will cost almost £100 to replace in the UK. I'd hate to buy a new PSU only to find the motherboard is dead or something.
I've tried removing memory, removing all internal devices and unplugging the power from the CD, DVD and floppy drives to no avial.
