Hello! I was playing with my friends at night when my mom called me to have dinner. I turned off the PC, and when I turned it on again it had no video. The next day I woke up and it was working again, but when I turned it off it was not working anymore. I unplugged and plugged the GPU but was still not working. I changed the power supply, reset the BIOS and still nothing. Ever since, it goes in this loop, sometimes it works (10%) and sometimes it doesn't work (90%).
I don't know what else to do, the IT guy said that the GPU was working fine because he tested it in another PC, but it is not working in mine.
