acpi bios error

I havent booted my proxmox host in awhile, its on a Asus PB60G Mini. It won't boot due to acpi bios errors. The bios is up to date, its on kernel 5.11, there are three versions of it available but they all boot to the bug screen and then blank, no signal detected. I've just about given up...

My dell optiplex 3080 motherboard died and got it replaced (from official dell support). Now, proxmox will not boot. More info: This host boots on a 256GB nvme m.2. Has zfs setup on a samsung 500GB ssd. It is using a usb to LAN adapter instead of the built-in LAN port due to some bandwidth...

I have just installed Proĉmoĉ VE 7.1. On reboot I get an ACPI Bios Error (bug): Could not resolve sŭmbol ...... \_SB._OSC.CDĜ1 ...... Can someone help me resolve this bug? I am using an old computer ĝith an ASRock Motherboard, Intel Celeron J-series, 1999MHz.
