I started up CS:GO and my screen turned a weird yellow color with darker yellow vertical bars on it. I turned it off using the power button and it wouldn't boot into windows. I took out the GPU and used the iGPU to reinstall Windows 10 using the recovery option. Sometimes it will let me log in but it usually shuts down soon after. My computer runs fine without the GPU in but with it installed I get weird colors/spots on the screen. It's not a loose connection, I already checked.

I also just noticed that when I turn it on the fans on the GPU spin up for about a second and then stop for a while then start up again. The mobo also lights up some red LED's in sequence when starting but one, called boot_device_led, seems like it stays lit up a little longer than the others.

Specs:
i5 4670k stock clock (was overclocked, set bios to default)
R9 270x
Asus Z87-A mobo
16 GB Kingston HyperX 1600 MHz
850W Seasonic PSU
