Help! Motherboard error codes

[FlyingMisaki]

Hello LTT,

 

I was using my computer normally and the screen went black out of nowhere.

I can't access BIOS and my monitor/peripherals have no signal/power. 10 minutes in, and I realize that the motherboard error codes are stuck on 68, 70 or 79 after each reset. (seems to be 70 most o the time)

I've tried swapping out the internal battery, re-seating CPU and GPU, running on a single ram stick, and switching to BIOS 2.

 

What should I do? I am clueless on how to fix this. Thank you in advance.
