I'm pretty certain that it's not that kind of error but damage from power surges. I removed the RAM sticks multiple times and tried other slots. I also cleaned out the tower multiple times and checked on all parts being where they should. Memtest is still running and did detect around 3000 errors and it's still scanning. Pretty sure the RAM sticks are damaged.
Cba to read. Did you solve the issue? If you haven't, and if you know how to do it, pull out your CPU chip and let me know if all the needles are there or are there any of them bent.

Everything is fine again, I replaced the severely malfunctioning RAM stick and added two others. Warframe works fine again, so I guess Freelancer and OBS will do as well.
