Dedi isn't booting, fuuuuck

Why does the KVM have CRT grain?

Also why is it garbage?

Anyone knows what might be wrong? Booting directly off either of the SSDs from the BIOS results in a black screen and blinking _ . This happened after a reboot after what I thought was a successful RAID recovery.
When I boot a rescue ISO, the RAID seems intact.
