Hi all

I was really hoping someone could help me out.

I am replacing the motherboard in my PC with a better Asrock H77 Pro 4 M.

I've replaced motherboards before so I know a tiny bit from YouTube videos about all the basics but this time, the thing just won't switch on.

My case is a crappy chinese made Coodmax K830 atx 750W. Even though its an obviously cheap brand, I don't think it is the case or the PSU because it was working perfectly before.

I am certain I've assembled everything else correctly so it is most likely the motherboard pins and would really appreciate some help. I've taken photos as it might help.

So these are the pins I've got.

I put the HDD LED Pin in the bottom right, the reset switch right next to it, and the power switch right above the reset switch. The writing on the pins face away from the board. This arrangement means there is a empty pin to the right of the reset switch and 2 empty pins to the left of the power switch. I hope that made sense.

My case doesn't seem to have a power LED.

Can anyone see where I am going wrong?

I've taken a few more photos of the motherboard if anyone could be so kind to take a look and spot out potential things I've done wrong.

Any help would be most appreciated.

Thanks all

I think for the power switch, you want the white wire on the left pin.

I do believe I have your problem solved. It appears (from picture photo4ke) that you have a PCIe 6 pin connector into your ATX header on the motherboard. You want to use the ATX 4pin, 4+4pin or 8pin - may say ATX or CPU on it. The 6 pin, 6+2pin, or 8pin PCIe connector will not work there (+/- reversed).

oh dude thank you so much, that was it.

I plugged it in and it worked liked a charm

You legend.

While I'm here can I just ask you another question.

I have 2 seagate 1tb SATA drives.

one of them has windows 7 and was my previous master drive. When I installed the new HDD, I unplugged the cable from the old HDD, and installed windows 7 on the new one.

Now im thinking about plugging in the old one, so i can have 2 drives.

my concern is that since both have windows 7, the system might just choose the old one...

would this happen or will it let me select in BIOS?

does it matter which SATA ports i connected the HDDs to on the Mobo?

You're quite welcome - thank you for the additional pics so we didn't have to guess all night.
As far as having the two HDD's with win 7 on them... On many motherboard it does matter which SATA headers are used for your boot drive (most often the 1st SATA bank is preferred). The computer will attempt to boot from the first HDD in the boot order. If that's the older HDD, the most likely result will be that the computer 'hangs' during windows loading (the OS is tied to the hardware), changing your boot order should fix that (if it happens). I think I would personally do a complete format on the older drive but you may have programs/data you want to access.
