My PC was working fine. I went into BIOS cuz Ryzen Master said 3.9 Ghz, while CB15 said 3.8 so I was like, well, who's right? BIOS confirms 3.8 Ghz. So I said, well why not? And over clocked ramy to 3200 from 3000 and 3.9 from 3.7 boost. My PC booted and I went to BIOS, fine. I left BIOS to bench when It crashes. I assumed RAM, boosted back into BIOS, and lowered to 3066 (which is stable). Once again, it booted, this time crashed and into safe mode. I opened bios, and lower back to 3000 and 3.8. I saved and booted, but now I won't boot, even to BIOS. My fan and keyboard light up, buy my monitor says no signal. I tried clearing CMOS with short, no result, and now I took battery out. What else can I try?
