At first, my PC was showing issues only during heavy usage — like when rendering or playing games. The screen and case LEDs would flicker rapidly, repeating several times. Eventually, the screen would go completely black, the LEDs would shut off, but the fans and the system would remain on.

A few days ago, the same issue happened again. I manually set the fans to maximum speed, and surprisingly, it worked. I was able to play a game and then shut down the PC normally.

However, now the computer doesn't power on at all. There's no response — no screen, no lights, no fan movement. It's completely unresponsive.

If anyone has experienced something similar or has any ideas for a solution, I’d really appreciate the help.
