I built 2 computers the same one for me one for my son. His is working very well and mine started out fine but then after about 1 1/2 hours of gaming the screen went black and wouldn't come back on. I had a CPU light on my mother board so after some effort troubleshooting it online, I removed the CPU and could see some brown spots on the bottom of it. I sent it back as defective and ordered a new one. When I got the new CPU, I installed and started up the computer the GPU light came on right after and then the Boot light. I removed the HDMI from the graphics card and installed in the motherboard. The computer boots up after that. So now something is wrong with my GPU. I installed my other GPU from my son's computer, and it works. I'm not sure what is causing the issues or if they possibly just burnt out at the same time. Can someone please help?
