I thought I had ruined my computer. I have no idea if this could have done any damage. I followed this video and did exactly what he said

https://youtu.be/cigqx4x0qqQ?si=DN-z3va2vnfVCtwT

Basically these settings:

Cpu ratio 42 (4200mhz)

Cpu loadline calibration control mode 5

Core voltage 1.28

Disable c state control disabled

Pss disabled (cool n quiet)

Svm mode disable

This led to my windows trying to auto repair, after a few restarts it just goes to a black screen. I manually restarted, did nothing but black screen.

So I removed and reseated the battery in the mobo. After entering bios and checking everything is back to factory ( global c state was still disabled weirdly) I was able to start windows normally.

Is it possible I've damaged a component? Is there a way to check? Would it be folly to try another, safer overclock?

Thanks for reading
