Video stops after startup.
Video stops after startup.
My gaming setup has remained stable since its construction in 2020. Recently, when I powered it on, the video output ceased functioning. My system uses a dual-boot configuration with two NVMe drives; the primary drive runs Pop!_OS. During boot attempts, I noticed the MOBO splash appears initially, but the display fails once the login screen loads. I suspected a driver update issue, so I switched to the Windows installation on the alternate drive to test compatibility. The same failure occurred there. I then replaced my graphics card with a known working model (GTX 1660 Ti) and reattached it via a different PCIe slot. Booting into Windows resolved the issue, confirming the problem was with the original card. I attempted to boot into a Linux live environment and a Windows installation media, both resulting in the same video failure. I also tried to access a Linux ISO, but that didn’t help. The display remains unresponsive until drivers are fully loaded. It appears the issue stems from driver conflicts or compatibility problems. I’m unsure what to investigate further—any suggestions would be appreciated. You can view my build details here: https://ca.pcpartpicker.com/list/TpGgGP
It's clearly a homework assignment. Because you tried it, the GPU isn't the problem—MB and PSU are the likely culprits. I'm leaning toward the PSU.
It seems your board is probably the culprit. A PSU might be the issue, though it's uncommon for a PSU to be so sensitive. Usually, when they come out, they're gone—especially in my experience. Motherboards can be in disarray depending on the problem. If you have another PSU nearby, try replacing it first since it's cheaper. Still, it's a good guess that if the PSU can't solve the problem, the motherboard is likely the cause.
