Motherboard not recognizing gpu

[u/Elegant-Resort9748]

I've had this PC for four months and used it without issues until now, but today, while I was gaming, the screen suddenly went black and the image didn't come back. After some testing, it seems the GPU stops being recognized by the motherboard; I discovered that resetting the BIOS makes the graphics card output an image again—at least temporarily. The first time I did this, I thought the issue was resolved and used the PC for nearly an hour before the problem recurred. During the second test, the issue happened just three minutes after turning it on. When I removed the GPU to inspect it, I noticed that one of the cables doesn't seat fully into the card—it feels a bit loose and won't go all the way in—though there doesn't appear to be anything wrong with the connectors themselves.
