Monitor loses signal about 10 seconds after the computer has begun to boot, no matter what OS I use

I've been trying to set up an older machine for a Minecraft server and it just won't cooperate. It was working fine right before it was no longer being used and put away, but every time I try to load an OS on it with a flash drive, the monitor shuts off after about 10 seconds and I can't get the signal back no matter what I do.

I have tried Windows 10, Ubuntu 22.04, Manjaro (KDE and XFCE), and Lubuntu 22.04. All of them had the exact same issue; I can usually get a splash screen and Linux can get to GRUB, but the monitor just loses signal after that. What should I do?

Basic system specifications:

CPU: Xeon e5-1620 v2

Motherboard: some Chinese X79 motherboard

GPU: GTX 750 1GB

RAM: 48GB ECC DDR3-1600MHz

Storage: 128GB SSD

Thank you to everyone and anyone who is willing to share any ideas. I have tried reseating the GPU, using a different monitor, and using a different cable, none of which helped sadly. I'm using VGA but that should be irrelevant as HDMI and DVI didn't work either.
 
Sounds like a faulty GPU and whatever base drivers beyond the generic VGA driver causes the card to crash. You could install another card or safe boot windows with only the generic VGA driver installed and see what’s happening.

Does the OS continue to load after the monitor blinks out? For example if you know the password try using Remote Desktop to login, or see if it responds to pings.

Just for shits n giggles have you set the correct time and date in the BIOS, have you disabled all other devices and or checked the voltage at the 12V PSU connectors?
 
Disable secure boot if it is enabled in bios. If that still won't work, try enabling compatibility mode ("disable" UEFI).

I have an old laptop with a GTX660M, and that will work perfectly fine with secure boot enabled. Until proper drivers are installed. Then I will only get a black screen. Disable secure boot and everything is fine again. Still have UEFI mode enabled.

Yeah, the OS continues to load. I can tell because the fan speed seems like it's fluctuating a lot and then settling down as time goes by, much like a computer does after booting into Windows.

The voltage at the PSU connectors is fine, doesn't seem to be off by more than margin of error or manufacturing tolerances. It's a 350W Sparkle/FSP unit so it's pretty good quality and it is my most trusted power supply. I will try another GPU when I come home today to see if that allows the computer to stay on longer.
 
What monitor and vid inputs are you using? You say usb flash drive, put the OS on the SSD.

No confidence in that board at all.

I'm using VGA directly from the graphics card to a monitor, no adapters or anything.

If the monitor stayed on long enough, I would have done that... that is what I am trying to do.

I don't really have any confidence in it either, hence my wording.

My card doesn't even have DP, but I appreciate it.

UPDATE: I tried the GPU in another system, and it worked fine.. also verified that the memory on the old Xeon system was fine, and it is. I tried a bunch of known working non-ECC DDR3 sticks, and it didn't help. I also pointed a desk fan directly at it to make sure nothing was overheating and that didn't help either.

Sounds like the cheapchinesium mobo at fault.

Did you try your monitor on another system you said it worked in?

I did. I think you may be right, the motherboard is likely cooked; the amount of time it stays on seems to be getting shorter. I just tried a CMOS reset for shits and giggles, and that didn't help. At least I can probably still sell the RAM, not worth buying into another platform that uses ECC DDR3.

Maybe I will build a more modern budget kind of thing.

Yeah just grab a Ryzen 5500.

Dont bother with that crappy mobo.
