I know that a computer won’t boot without RAM, but i wanted to see if it would at least make noise or the fans would spin, but neither happened? Do I need a new PSU and Mobo or just RAM to boot?
Even without the ram, the PSU is under load by the motherboard and its' fan would spin up, power the motherboard, and provoke a 3 beep error indicating no ram on motherboard error, hard drive would spin up, and case fans would run in default mode.
the psu needs replacement for the lack of any of those reasons.
