This issue might happen due to RAM.

To resolve this issue:
Turn of the power supply for your desktop.
Please remove the side case on your tower(CPU).
find the RAM slot and remove the RAM from the Slot.
Clean the RAM terminals with the help of cloth or Eraser.
After cleaning place the RAM on RAM slot.
Now try to turn ON the PC desktop. If it is working thats fine or else you need to replace another RAM to check.

Please refer the below figure to find the RAM Slot and the lock to remove the RAM.
