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.

  • Why won’t my PC start up?

  • 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.

  • Why won’t my computer boot after installing a SSD?

  • However, if you restart the computer a few times, because the platters are already spinning, it can sometimes boot. Newer SSD (solid-state drives) don’t have platters. If you are encountering this issue after installing new hardware on a computer, it is also possible that the power supply is no longer adequate.

  • What can cause a computer not to boot to the OS?

  • This includes everything other than the power cable, the display cable attached to your monitor, and a keyboard to navigate menus. Attached peripherals like external hard drives or even USB-powered mice can potentially cause issues with power, driver conflicts, or issues with boot order, and can keep a system from booting to the OS.
