Red led

[Epitome]

Do you have a hard drive with an operating system connected and powered? Because you said "boot device led"...

no, i'm just testting the graphics card, cpu and motherboard

[Epitome]

So you're trying to test those components by booting an OS from a flash drive? Or what?

no, i'm not booting from an os at all.

[squid4fl]

Ah ok. Then you have to press "delete" to get into the uefi/bios. If not, thats probably why the led is lighting up. Because your pc cant find an operating system to boot.

[Epitome]

Well, then you're having this problem because your PC isn't finding any OS to boot.

Is this also causing the fan on the stock cooler not to spin.

 Also the fan on the stock heatsink is not spinning

 

Uhm .. I don't know guys , maybe but maybe this might be the problem ?

 

Try put the fan header again or in another header . I'll take a look in the manual ..

 

Did you connect all cables from psu to motherboard ?

I've connected all the necessary cables. The fan header is in the cpu-fan header

It says b4 and then 99.

[Uranus]

Ok , you still didn't told me what led , the 99 error is because some part failed to initialize , it's either because is not properly connected or lack of power .

 

Go check every part and then check the tpu switch , it should be all the way to left .

[Uranus]

P.S. : B4 is caused by an usb hot plug , so unplug everything and if it works try just with mouse and keyboard .
