Recently I faced a major issue where my PC's screen abruptly stopped, though it kept running normally. Fans spun, keyboard and mouse functioned, audio worked, and everything else was fine. This happened yesterday but resolved after a few restarts. During a gaming session today, the problem reappeared. I replaced the RAM and checked the CMOS battery. All cables seemed intact, my PSU and motherboard were okay. However, when I connected the HDMI cable to the motherboard it worked, but with the GPU it still displayed the same error. After waiting a few minutes and restarting the PC (plugged into the GPU), it turned on briefly before failing again. After an hour, it started working properly for about an hour, only to repeat the issue later. What might be causing this?
