HX620W Possible Fault

Hi Guys,

 

A couple of days ago my pc suddenly stopped working for no apparent reason. When I say stopped working, everything fires up but it won't POST so I can't even get access to the BIOS.

At first I thought it may have been a faulty graphics card (and may still be) and then somebody said have you checked the voltages on the PSU.

So I have checked all the voltages with a DMM and these are the readings:

 

+3.3V reads +3.418V

+5V reads +5.05V

+12V reads +12.07V

-12V reads -10.58V

 

With the -12V rail being only -10.58V, is this enough to stop the PC from doing the POST?
