My GPU works fine; it runs like it should until my pc goes to sleep or I reset. When my pc turns back on, I get a red light on my motherboard indicating that there is something wrong with the GPU. The only temporary solution I found so far is taking out the card and putting it back in - this works until the PC is turned off again. I'm assuming that the video card is just loose..? But if it is, why doesn't it stop working randomly instead of after every reset?
