I've been using this PC for about four years now and suddenly my GPU HDMI and DVI ports stopped working and my PC won't detect my GPU at all. I can still boot the PC with no other issues, just by using the HDMI port on the motherboard. The GPU lights still come on, but other then that I get nothing.

My GPU is a GTX 970, and everything is connected properly, I haven't opened it up in weeks.

Anyone have any ideas?

The fans on my GPU don't spin until it reaches a certain temperature, and my PC doesn't detect my GPU so I can't use a program to test them out. I have double checked and everything from the power supply is plugged in, I even tried a second set the cables from the PSU to the GPU and still nothing.
