So my PC used to freeze everytime it got bumped a little bit and I would just have to restart it and it would work again. But now when I try to turn it on it will start up for about 5 seconds, then shutdown, then start back up again and the fans and everything will be on but it wont boot up and says no input signal, I cant even get to BIOS. I have tried unplugging everything and testing everything but nothing works. I was getting really frustrated and kicked it and then it suddenly booted up to this screen that said overclock failed press f(something) to boot, and I did then it took me to the BIOS and I exited that and then it worked like it always did. But everytime it shuts down or goes to sleep I gotta kick it or move it around to boot it up again. Also when I power it off it just restarts itself and turns on again. I was able to search for malware when it came on but found nothing. I can't figure it out.
