Why won’t windows 10 boot?
Windows not booting is an extremely common problem for people to have, this is due to the fact that Windows can break at any time from almost anything, including its own updates. That’s right Windows 10’s own updates can cause your PC to stop booting, Thanks Microsoft.
Enter safe mode
One of the first things to try is to enter safe mode. This is an environment where windows will not open any background apps apart from the ones required and has the option to disable internet connectivity. Unfortunately, the only way to get to safe mode while being unable to currently boot into windows is to have the boot process interrupted 3 times in a row, so once windows begins to boot hold the power button to force turn off your PC. After doing this 3 times windows should then boot into the recovery mode once you turn it on again. Once in recovery mode head to troubleshoot, advanced options, start-up settings, and click restart. Once your device restarts select the start in safe mode option which is usually option 5. If you were unable to get into the recovery menu check some of these other options.
Make sure the display is plugged in properly
It may sound simple but if your computer is showing a black screen with no logos or visible attempts to boot into windows, your display may not be plugged in properly. Check the back of the PC and see where the cable is plugged into. If you have a graphics card in your PC there will be 2 areas where you can plug your display into, one usually towards the top on the motherboard near other ports like USB, the other place it may be is towards the bottom, it will be a separate metal plate containing only HDMI or display port connectors. If you have that separate graphics card port towards the bottom make sure your display is plugged into those, as connecting your display to the motherboard when you have a graphics card can cause the display to receive no signal at all. If you do not have the separate graphics connections towards the bottom, then it is the correct to connect your display to the top display ports on the motherboard. If you have a laptop this wouldn’t apply to you, however if nothing you try can get your screen to display then you may have a broken screen and might have to get it repaired.
Check the components in your PC
If your screen is blank and the PC doesn’t post, and you have made sure that the display is connected correctly. Turn the PC off and unplug it from the power. Open the left side of your tower PC by removing the screws at the back that hold the left panel on. Once open, check to make sure the RAM is connected properly to the PC. The ram is usually located next to the CPU and are thin sticks connected to the motherboard using similarly thin connectors. If the ram is not connected properly make sure it is lined up and that the tabs on each side of the connector are up, then push gently until the ram stick click in on both sides. Now turn the PC back on and see if it posts. If it does you can turn the PC back off and put the left panel back onto the PC and screw it back into place.
