I was having the same problem im about to explain with my old pc, so i bought new case new motherboard new ram and new cpu, kept my liqued cooling and psu and gpu to transfer over and im still getting the same problem. Computer turns on, fans run, rgb runs, no display to monitor and after about 40 seconds pc turns off. No clue as to what the problem is, ive replaced almost all of my pc's components and dont have the money to keep buying and replacing until it "magically" works. Any help/feedback is extremely appreciated.
