Light appears but screen remains blank.
I purchased a new Samsung 990 Pro and was attempting the installation. It was my first PC and I wasn't familiar with the M.2 port on my motherboard, so I connected it using the same cables as my two HDDs. When I powered it up, it didn’t recognize the SSD. After turning it off while the PC was running, it shut down completely. Later I located the M.2 slot but the red VGA indicator stayed lit and my monitors showed black. I tried disconnecting the GPU and using a different slot, but when the PC was off I unplugged the PSU, thinking it was an HDD issue. Now I’m stuck and need the system up and running for work tomorrow. Intel® Core™ 12th Gen i3-12100F, GFORCE GT 710, EVGA 550W
The GT 710 seems unlikely to support UEFI due to its reliance on a 2010 architecture. Since POST LEDs stop at VGA, it's probable that newer systems would avoid CSM for compatibility reasons. The presence of an Intel F variant chip without built-in graphics further limits troubleshooting options, making it less likely to run UEFI smoothly.
