Question Problem with EVGA GTX 1060 6GB

Apr 26, 2022
CPU: Intel core i5-6500
Memory: 4x4 GB RAM
Mobo: GA-H170 Gaming 3
Storage: 2x500 GB SSD, 3x1 TB HDD
GPU: EVGA gtx 1060 6GB
PSU: Thermaltake TR202 600 W

I've had this system for going on 6 years now, and have just recently started having issues with my GPU. I realize it is probably just in need of being replaced, as it has been so long, but it still works perfectly fine--when I get it to work. After a while of using my PC, the fans on the GPU whir up to 100% and sound like a leaf blower and the signal goes dead. After I reboot, my PC posts but I still get no display output from the GPU. When I put the GPU into another PC that runs ubuntu, it works perfectly fine every time. Sometimes after I take my GPU out of the other PC it boots right up like nothing is wrong. Scratching my head over what is going wrong here... Could I somehow check for a dead PCIe slot on my mobo? What else could I do to narrow down that the GPU isn't dead?
