Hi, I have bought brand new ASUS X470 F gaming motherboard. Everything was working fine until one day I tried to do some overclocking. I tried running 4GHz on all cores with 1.3v and computer hard crashed. No problem, I just restarted it and I gave bit more voltage. 1.35v this time. Just to see. And it happened again. I reset cmos and I also tried setting bios back to default. I keep getting the problem that pc boots or normally but display shows no signal. I keep rebooting a couple times more. Display is back again. But then randomly on another restart, I might get the issue no signal. And then again works normally after more reboots. Sorry if this whole story got really messy. I tried to explain what happened detailed. Any ideas what might be a problem?
