Power Supply or Motherboard

[PCTech74]

Hi!
We have a computer here that was installed/configured before I took this position over. It's a custom build so I can't give you a make/model.

Over the weekend it just stopped working. It will not power on. No lights, fans..nothing. How do I determine if it's a bad power supply or motherboard?

The motherboard (Gigabyte GA-81DX) has a single solid amber light on when I plug in the power cord.

Any thoughts? Suggestions?

Thanks
Pete

Amber light on MB indicates a power short somewhere ... I suggest trying another PSU first as it is easier to fit than replacement of the MB

It will not power on. No lights, fans..nothing

Another indication of a possible faulty/dead PSU.

Thank you muckshifter. The power supply is ancient so it was hard to find..and it's refurbished! I will give that a try and see what happens. The user claims the power supply had gone out before so I think it's time for a new PC.

Thank you muckshifter.

... so I think it's time for a new PC.

That sounds like a good plan.

That MB was usually fitted in an Advent PC ... not the best of brand names I can think of. Is very old by today's standards, needless to say, they don't make them anymore, and, you will be a little pressed finding a decent replacement MB for that era.

I wouldn't try and upgrade a s478 to be honest now.


Was it Advent exclusive? Because its a bit weird getting one for a custom build if it was?

Well the PC has a variety of products in it...american megatrends, gigabyte, aopen... It was pieced together before I started here. It's about to be retired though so..

I did get the replacement power supply today and everything came up ok. I believe one of the HDs are about to fail though.

Thanks for all the input!!
