Wait... If the HDD light is plugged into the Power pins, what is your Power switch plugged into?

Sounds to me like your pins are all mixed up. Did you download the correct manual? Every mobo has a different pin arrangement, for some stupid reason.

There's even a picture on the fucking motherboard lol, for some dumb ass reason that's the only place it'll light up at.

What are the model numbers of your motherboard and power supply?

g31tm-p21 is the motherboard model & it's a iMicro 400w power supply on amazon for about $17 lol.

Do you have a video card?
How many drives?

Ok so think I narrowed down the problem. It's the 4 pin connecter. Everything boots up without it but stops when I plug it in. Hmmm.

Is it possible to just clean the 4 pin thing inside the motherboard or something then it'll work?

You mean the 20+4 pin power plug?

I think the 4 pin is required when using pci express... Hence why I asked if you have a video card, or if you are using integrated graphics.

If no video card, don't use the extra 4 pins. If you are using a video card, I think the motherboard needs the extra power.

Perr when I plug in the 4 pin all the power shuts off. Pretty stupid. Is the 4 pin connecter like dirty or something ??

Coming to the conclusion the motherboard is fried, if any one has a mother board sitting around & can give me it I'll happily pay for shipping costs.

have you actrually tried another psu? D:
It could be you're psu, but if you dont have a spare you'll find out with you're next build.

And it can be a flat head or Philips so long as you can bridge the 2 pins together, but only for a second till it starts.
If you have done that and nothing happens its you're best guess to troubleshoot. RAM, PSU and even try a PCIE Graphics card.

$17 for a PSU. Well thats gotta be loaded with shitty CrapXon caps... If even one of those capacitors fail the PSU will wreak havoc on you're system. It may explain why you're system wont start properly.
Try spending 40-50 dollars on a decent brand.
