Hello, I seriously need help with my PC. A couple of months ago, my assembled pc started behaving strangely. It wouldn't boot up if I started it immediately after shutdown. It showed power to the fans and the motherboard (but not my mouse or keyboard). It needed 30-40 minutes at first, and the waiting time kept getting longer. I figured that the problem was with my old PSU and I got a replacement. It worked perfectly after that and I thought my problem was fixed. But today when I started it up I ran into the same problem again. And it seems this time waiting won't help with startup. Why is the happening? I'm incredibly frustrated.
