computer won't start
Forum Homebuilt Systems : General Homebuilt - computer won't start
computer won't start.
when I press the start button the PC momentarily boots (for a split second) then dies.
I have to pull the plug from the mains wait a few seconds, plug it back in, disconnect and re-connect my second SATA HDD (DUMP ONLY) and keep repeating till it fires up?
the problem re-occurs the next day after it has been switched off all night!
any ideas?
mainboard (sata)?
power supply?
HDD? ('final recovery' reports no problems)
cable?
thanx in advance

Hi...
yes it is home build.
yes it has worked fine for a few years now. This is the first fault.
thanx!

I'll try that after it's been off all night and see what happens.
thanx

my PSU is AHANIX/SILENT-X. (high mileage).
thanx

do I need a new one then?
no other way to test or fix?

PSU's have 'fried' me before!:hot:
thanx for the recommendations
