I've had my PC for only about 6 months now, custom built by me. In the past months I had noticed games aren't running as well as they should be, but I just thought it was the game until I realized it was all games that can't even run on low settings. Whenever I try to open the NVIDIA Control Panel I get the message "NVIDIA Display settings are not available" and then it says there's no display attached to the GPU. I've disabled and enabled the driver in Device Manager and I've tried plugging my monitor into the GPU, but nothing shows up on the screen. I feel like I've tried everything and it's still not working. The lights and fans work fine so the GPU definitely works to an extent.
