So my PC wasn't booting correctly for some reason today. I would try to boot it up and it would die after a few seconds, and then it would try to boot up again but die after a few seconds again, and it would continually do this. I reset my CMOS and now the computer boots up normally and dies after a substantial amount longer (20+ seconds or so), and then when it boots up again it stays on indefinitely like normal. However, when I plug my display in, the display recognizes the PC but says there is no input coming from the PC (neither onboard nor GPU). I have a feeling this is a PSU problem, but the lights, fans and drives all spin up and turn on normally. Please help!
