Issue resolved after CPU cleaning.
Issue resolved after CPU cleaning.
I began cleaning the computer by removing the cooler and applying thermal paste. Once everything was back in place, there was no signal notification. The PC functioned properly, the graphics lit up, and the CPU fan spun. I tried nearly everything since changing the HDMI cable, removing and reinserting the CPU, and doing the same with the graphics card, RAM, BIOS battery, power supply. The issue persisted. Interestingly, another graphics card from a different PC caused the same problem. When I returned the card to another machine, it also failed. I found an old computer in the attic, installed the card there, and a picture appeared. What could be causing this malfunction on these two systems that were previously working? Please help.
Here’s a breakdown of the components: video cards, system specifications, and past configurations. Let me know if you need more details!
