I woke up today to get on my computer so that o could finish Lies of P, it worked perfectly fine last night up until around 3:30 am when I got off, when I woke up today, my pc would not boot, I’ve tried disconnecting my cpu power, the 24 pin connector, and a new ac power cable. My monitor that it is plugged into my onboard graphics through the motherboard but the system just will not power on, would it be safe to assume the PSU needs replaced?
