Computer won't post

[Enderstream]

Hi.
My friend recent got a new chassis and asked me to switch his components from his old case to his new case.

Among building everything went smoothly, but first time turning the computer on we got no signal. So I tried with on board graphics and no signal. Tried with an old gpu and no signal.

I havery
-reset cmos
-changed ram to a different slot
-used another graphics card
-checked all cables
-repeated the cpu

We managed to finally get the pc to post but it freezes if we let it run past post or if we try entering the bios which causes us to restart the computer. Once we restart we get no signal again.
To get signal back we have to Unplug the power from the poversupply and wait 30 seconds then try starting the computer again to get a post. Then the freezes begin again.

I'm pretty well with building systems and computers but I'm honestly lost here.

Anyway any help would be greatly appreciated as I'm currently in the bad spot as my mates pc was working before this

Thanks

Please list full system specifications, be specific. Include power supply make and model.

Your power supply is rather low quality. It's possible that disconnecting and reconnecting it may have been the end of the usefulness of the unit.

I'd recommend the Seasonic S12ii 520w for your machine. Please ignore the fact that it's only 80+ Bronze, as that's merely an efficiency rating and is completely unrelated to the total quality of the unit. This is a great unit for the price. For a single CPU and not so power hungry graphics card, I can't really justify the cost of a more premium power supply.

This one is not an immediate problem but rather something to consider in the future: your motherboard has no heatsink on the MOSFETs (those little black chips to the left of the socket). This greatly limits overclocking potential on that board. Pushing MOSFETs too hard without keeping them cool will blow them out. When they blow out, you'll get 12V straight to the CPU. For the sake of your CPU and motherboard, don't try to overclock an FX 8xxx or 9xxx chip on that board.

Low quality? It won a Hardwaresecrets Silver award.

Techpowerup's power supply reviews aren't quite as detailed but in the testing they did do it did quite well.

What the power supply is, is potentially old. How long has it been in use? It's an older model and it could be going bad due to normal capacitor aging.
