FB Purchase has an issue
My friend bought a used NZXT off of FB and it shuts down completely while he's playing. I tried logging into the pc but it didn't have an internet connection and wanted a pin. He's never used a pin. He got excited and changed his security online at MS now i can't get logged into it. So I have a couple questions not related to the log in. It is a 2021 by the serial number and has a B450 mb, G-Skill ram A2 16gb, B1 8gb, B2 16gb. AMD ryzen 5 3600 cpu and a 700w thermaltake psu. I boot to bios and the cpu idles at 45c. I wanted to do a stress test but afaik you can't do it in bios. I put a brand new 850w psu I had laying around and that really fucked it up. I put the old one back in. I read that doing a cmos reset can fix the psu issue, never heard of that. Usually a fast shut down is either a hot cpu or a psu problem. I know this isn't much info but any idea? He hasn't modded it at all or oc'd it. The 3 sticks of ram bother me but it was fine until recently. BTW it has a GeForce RTX 3060 Ventus 12GB GPU.
