Hi All,

I built a computer back about 6-8 yrs ago. I have a Gigabyte mobo and it was working fine until a few years ago but i just got to really seeing what the issue was. One day it would not longer turn on at all. I thought it was the power supply so I tried the bobby pin technique and it works. I reconnected the 20-pin connector to the mobo and everything powered up for a brief second and then died. I thought it must be the way I am connecting it, even though it snaps in place nothing happens. I decided to push down on it with some force and turns out my computer works just fine as long as I apply a good amount of pressure on the connector. I don't want to break my mobo as a result of pressing too hard.

Has anyone ever encountered this?? I would like to avoid have to search for another mobo as this is a Socket 939 and I don't think they even manufacture these anymore.
 
Hi

either there is a problem with the plug connected to the PSU
or there is a problem with one of the pins in the socket on the motherboard

If you have access to another PSU this will give you a clue where the fault lies

Remove the plug (connected to the PSU) and with a small screwdriver check for a a pin which is not fully down at the same level as the others.

(Actually the socket on the motherboard has pins and the plug connected to the PSU has cylinders which should be pushed down onto the pins)

also look for burn marks on either plug or socket (caused by bad connection causing over heating)
