So I have an 8 year old PC that has worked fine the last years. Howver this week something weird happened. No signal and no POST.

So I tried a variaty of things: reseating GPU, using onboard graphics, reseating RAM, removing all RAM (no beeps), removing CMOS battery, CMOS jumper. However I did get to the BIOS setup screen once, heard a POST beep (so speaker works fine), but after hitting save and exit the PC just turned off and it never got anywhere else since then. Only spinning the fans.

So considering I did get to BIOS screen once and without RAM no beeps were given, is the problem likely the mobo or can it be something else like the PSU?

Thanks in advance.
