Computer shuts off while installing Windows

[Stalfelz]

Instead of making another topic, I'll just edit this one. So yeah. Got the computer working, but now it just shuts off while installing windows. Always when it gets to "getting files ready"

If it's not one thing it's another. Not sure what I could have done wrong this time. Bad ram maybe?

 

I just completed a new build and tried turning it on for the first time, but I get no signal to the monitor, and the motherboard shows code AA. I looked it up, and it just says "reserved" so I have no idea what's wrong. Has anyone else had a similar experience and been able to figure it out? I really have no clue what to do, and I'd rather not return everything just because I couldn't figure it out.

CPU: Ryzen 5950x

GPU: EVGA RTX 3080 FTW3

Mobo: GIGABYTE X570S AORUS Master

Ram: CORSAIR Vengeance LPX 64GB (4x16GB)

So it turns out one of the connectors to the GPU had popped out slightly. Everything is working now. Please disregard this dummy.

So I tried to enter bios, and it told me that bios had been reset, and that I need to reconfigure them. Now it shuts off immediately after turning it on, before I even have a chance to try and enter bios. wtf

Check that the cpu cooler is properly installed.
