installing internal soundcard inside a hp omen 45l

[zoddan]

Hello, Im trying to install a creative ae5-plus soundcard into my omen PC.
It does not appear in the **bleep**ty BIOS nor in device-manager inside windows. 
I've tried the card in another computer and it works flawlessly, I suspect the speed on the PCIE4 slot might be the trouble or it might be broken?
Any ideas?

Plan B is to compltely slaughter the entire system with a new motherboard. It's a real shame to rip this rig apart but this disgusting mobo is a complete joke in my opinion. 
I'll be a very happy bloke if you guys can help me or HP-support can respond.

Realtek audio sounds like plastic in a can, it's complete cancer in my ears.
