Could someone help me with my graphics card? I'm not a repair technician, but it's a hobby of mine. I recently purchased a GTX 1650, but I'm having an issue. I can use it, but after a while, the screen goes black, the video disappears, and the fans, which are running at full speed, sometimes stop working. I leave it off the motherboard for a full day, and the next day it works. I've checked the voltages, and sometimes it reads 0V where it should be 5V, sometimes 0 at the 12V input, and so on, as if they take turns. What could it be? HELP!
