Power Problem

[kagai]

I've had periodic shut downs for a while, but I really didn't try to troubleshoot it until I took off my CPU cooler to redo the thermal paste. After I got everything back together my PC wouldn't turn on at all; however, the motherboard's reset and power buttons were lit.

After some searching, I find out that my main power cable that connects to the motherboard is where the problem is at. If i move the power cable a little the system will power on, if I let the power cable go, it will power off.

So, I am thinking I have either a faulty wire in my power supply cable or there is a problem with the main power connector on my motherboard. I don't have any spare motherboards/power supplies in order to test one or the other. Does anyone have any ideas on which is the most likely culprit? Or, how to test it without having an extra power supply or motherboard?

I have a Corsair 850TX Series 80 Plus power supply and an Asus P6X58D Premium motherboard.

Thanks for any help.

First look at all the pins on the mobo and the plug connected to the psu. Maybe one is loose causing your problems.

Without you having the option of spare anything, its really hard to pinpoint which could be your problem. I do have a PSU tester, similar to this http://www.newegg.com/Product/Produ.../+PC+Service+/+Acc.-_-APEVIA+CORP.-_-99161001, but I do enough repairs for people that its worth it to me. There are cheaper ones out there, but if your mobo is the problem, diagnosis becomes much harder.
