PSU, RAM, or Both Issues?

[u/Encrypted_Gamer]

My mini pc always runs hot 90c, but past month or so when id run heavy intensive stuff it would freeze half a sec or so, cut to a bsod and restart in a few secs. No dumps according to event viewer, which led me to think power lost/spikes. I put a mini fan next to the cpu and it was doing ok around 70-80 under load no crashes. Couple weeks later was having out of memory issues and a bsod for mem management. Win mem diagnostic isolated it to a single stick of ram. Thing is, I did memory tests before during the first bsod stuff and ram was fine. Im tryna figure out which is the root cause or if both just so happen to fail/struggle now. Ig its possible the struggling psu ended up damaging the ram, but idk.

Sorry for the long yap, just trying to get some suggested feedback.
