Unstable Boot for Zen 4 7900X Model
Unstable Boot for Zen 4 7900X Model
I recently assembled this machine around two weeks ago. It was difficult to get it to start up correctly. I slightly adjusted the CPU cooler in case it had been over-tightened earlier. I've reset the RAM several times, and everything is functioning properly now. A BIOS update was installed and it helped a lot. Still, I encounter strange startup problems. The situation is inconsistent; usually I need at least three boot attempts before it boots correctly. The first attempt often ends with the CPU debug stuck red, then it goes into safe mode, after which it boots to Windows but fails to recognize the Ethernet and keyboard. The only time it boots without issues is when it connects to a different USB port, after which the keyboard works. However, only two of ten devices appear when it normally won't show up. I'm puzzled by this pattern and the lack of consistency. Ideally, the debug indicator would cycle through VGA, CPU, DRAM, and finish with Boot. It's unclear if I've ever seen debug lights change in that sequence before.
