Recently received some new parts for a home server I wanted to make, and found some help on YouYube on how to do it. I built it a few days ago, installed Ubuntu for servers 18.04.3 ,and went to go boot the server today.
CPU: AMD Athlon 220ge
Then, I got this line: "unable to write to iommu perf counter" followed by four more lines, which I could not read since the screen went black within a second.
It won't shut off or go into BIOS unless I force power off, but I'm back to Square One. I'm very new installing a BIOS, so I would appreciate it if you all would be patient with me.
