why does my computer not boot up first time

Best answer


Bad power supply or inadequate power supplyA bad, failing, or inadequate power supply often causes this issue. If the hard drive is not getting enough power during the first time the computer starts, it cannot spin the hard drive platters fast enough to start the computer.

  • Switch the button on your PSU to off over night and see if the system boots normally the next day (after switching the switch to on again first, obviously), it’s a windows fast boot fault.

  • Why won’t my computer boot when I press the power button?

  • If it’s something similar with yours, and simply pressing the power button doesn’t eventually lead you to bios and boot screens, then there might be some error in the jump from initialisation to boot. You may get the same behaviour unplugging the machine that you get for waiting long periods of time.

  • What to do when the computer is not booting?

  • Method 1. Clean Boot. If the issue still persists, I would suggest you to boot the computer in a clean boot state and check. Booting the computer in a clean boot state can reduce software conflicts and help identify the root cause of the issue. You can refer to this article for more information:

  • Why does my computer spin on but not boot?

  • I do not think it is a power supply issue because as you say everything spins on but does not boot. That means that power is getting to the components. The lack of a POST beep means that the mother board is not booting. I had this issue a few years ago with my first system and a bios update fixed it. PS.
