emachine 370 power supply problem

  Bigg-gee 17:18 29 Nov 2007

Strange what happened, I came home from work and my emachine was making a whizz sound, hd and keyboard lights were flashing with the whizz sound. I had switched it off the night before. I found a replacement power supply and when I connect this there is nothing...
Could my power supply have blown and caused damage to the motherboard or is it the motherboard that maybe had a problem and caused the damage.

What do I do next, I have just spent bucks to upgrade the memory, which arrived today and now I cannot even use it!!!

Help please anyone...

is the replacement psu a new one or a known working one from another pc?

Have you checked the fuse in the power lead?

Yes, a failing psu can take the motherboard and other components with it; quite difficult to work out which without obtaining replacements one at a time. It can sometimes be quicker to pay a small, local pc shop to diagnose the fault because they usually have spare bits available for this kind of testing by elimination.
