My graphics card (7800 XT) says there is 0 power coming from it, it wont load games, it crashes, this was after installing some cable extensions. I realized I wasn't getting any power so I unplugged them and plugged the normal cables in.
After doing this I realized that the small LED +, + reset, and power cables had unplugged and I couldn't plug themn back in without removing my GPU, I plugged everything back in and now it just wont work.
