Good afternoon,
I have a home workstation with an AMD CPU, Titan V GPU, 32 GB of memory, and a root SSD and /home on spinning disks.
Right now it has xubuntu 18.04 on it and it would boot fine. I shut it down and restarted it to get an inventory before I put CentOS 8.2 on it. It won't boot now. It gets to the grub menu and freezes. I can't use the keyboard to select an item in the menu and I can't press enter to make it boot or press "e" to edit the boot line. It just sits there (seemingly forever). Here's what I've tred:
1. New keyboard/mouse - no change
2. Different monitor - no change
3. Booting from the CentOS 8.2 iso on a USB stick - no change
4. Replacing the TItan V card with a GT 1030 NV card - no change
When booting from a USB stick, I get the BIOS splash screen and press "DEL" to get to the menu, but the menu never shows up. It just freezes.
This one has me stumped. Not being able to boot from a USB stick is really puzzling. I've never seen that before. Possible bad MB?
My apologies for using the list to help debug problems but since I'm moving to CentOS 8.2 I thought people might have some ideas.
TIA!
Jeff

It's not clear to me if the keyboard is working or not. I'd try a PS/2 keyboard if it doesn't and/or unplug and replug the USB one when the computer is frozen. What happens when you boot without a keyboard?
Put a minimal amount of RAM in and go through all of the modules to see if one or some of them are broken.
Replace the power supply.
Replace mainboard.

Replace all RAM or test it in another computer.
Replace the power supply.
Replace CPU or test it in another mainboard.
Replace mainboard.
If the board has a backup BIOS, use that to boot.

Hello
He said (or i understand) it worked with Ubuntu until tried CentOS. Maybe something about UEFI? Don't know, but, just to try.

Thanks everyone for the help! I'm still struggling to get it working. I think I will have to go back and start simple: (1) one DIMM, (2) New PS, (3) maybe new MB (I can't ever access the BIOS any more).

If you are going to discard all that, perhaps can try reseting the CMOS before anything. Locate the jumper and close it. BEWARE! Power disconnected from mains, or you can see your PCB tracks burning!

Good idea - I will try that as well.
