I ordered a couple upgrades online for my pc new mobo psu and an ssd I’m hopes of future upgrades but when going to turn it on for the first time it runs all lights on fans spinning then after about 5-6 seconds turns right off, without touching anything it attempts to turn back on by itself and then ultimate shuts off again. I tried everything and eventually got to removing the ram and booting it up without the ram installed and the pc stays on finally but obviously no post screen any advice or is ram just junk? And if so how does that even happen?
