Last night the display of my pc suddenly gone and cpu debug led turned on.
I was trying to force shutdown by pressing power button, but it didn’t work.
Then I unplugged my power cable to shut it down.
When I restart my pc, the problem has come again! Then I've tried several things to fix it, but failed.
I've tried:
  • Clean the ram with eraser (Failed).
  • Unplugged all the peripherals and trying to start my pc (failed)
  • Clear the cmos by removing the battery for 20 minutes and reset BIOS. (After this attempt, pc started on BIOS mood and I boot it in default BIOS settings. Then pc keeps running for 15/20 minutes. After 15/20 minutes the same problem came again.)
  • Lastly, I've detached my cpu cooler and processor and cleaned them. After reinserting processor and cooler and resetting bios again, the pc again run for 10 minutes. And the same problem has come.
  • I've noticed something, pc starts working sometimes, but after 10-15 minutes the same problem occures.
Pc specifications:
  1. MSI B460M pro vdh motherboard
  2. Intel core i5 10400 10th gen processor
  3. Silverstone 80 plus 500 watt psu
  4. 8gb ram 2666 mhz
  5. Verbatim 256gb NVME SSD

Literally, I got tired and exhausted by facing this problems. It’s very important for me to work on my pc.

Can anyone suggest me something to solve this issue? I'd be great full.
