Hi @Fishtown , Thanks for the BIOS update. RAM modules were tested per each and together as well. At the moment I'm trying to narrow the possible fault. As surprisingly the power supply is an entry level budget one, I replaced it with a branded one to see if that solves the problem. It's been almost a month now since my friend uses it, so fingers crossed. So again: the full configuration worked fine for about a year and a half, low-, mid level online gaming. Then started to freeze and got a boot loop. Couldn't get out of the loop, I thought it might have been an OS update glitch, as 'normal' for Windows. Reinstalled the OS, worked fine for two months - not everyday usage - but then it started to glitch again with the same thing. So I replaced the NvME just for testing. After a month problems came again, but a bit different. Turned out that he replacement drive had bad sectors, so replaced again plus replaced the PSU. That's where we are now. Any ideas much appreciated, thanks.
