Onboard graphics dead?

Hello,
I had to install an old mobo in a system and format a drive because it de-authenticated the previous version of windows XP

After the install, the resolution was forced to low with 8 bit graphics and had no options to change it. The monitor was not detected, and after a restart the screen remains perfectly black after windows loads. I am unable to boot to safe mode as it stalls on Mup.sys.
Is this mobo fried?

The 8-bit graphics could be because XP did not have a built-in driver for the graphics chip and instead used a generic VGA driver.
