Alright let me start right off:
Had a crash today while doing Uni stuff on my PC, afterwards I wasn’t able to boot the pc properly. Updated bios etc, nothing helps. My M2 SSD isn’t detected by my mainboard, so i called the shop I bought the pc at and they said it’s probably the ssd which is dead. I’ll test it at a mates pc now, if it’s not working I’m fucked since I had important data on it. Any ideas?
