It’s not many times that you turn on a computer, and it refuses to boot, at least not with the newer versions of windows. But what do you do when this unfortunate misfortune befalls you?
Look at the most recent upgrades and changes that you made to your PC. See if you recently installed new hardware drivers or connected new components to the device. Maybe you opened up the case and tampered with some hardware. It could be possible that you installed a buggy hardware driver or incompatible software. It may also be possible that you accidentally unplugged an important component inside your computer. This is why it makes sense to retrace your steps to the events leading up to our computer failing to boot. By so doing, you may find the cause and thus fix this problem.
Sometimes the cause of the problem is not as technical as we may erroneously believe. It may be a consequence of poor connection to the power supply, or even you may have forgotten to switch on some components. Check the power connections both outside and inside the computer; ensure that the power supply is not dead and that the monitor is turned on.
Sometimes a computer powers on but ends with a blank screen saying things like no bootable device or disk error message. This indicates that the system is not able to boot from the hard drive. To correct this, you should access the computer’s BIOS or UEFI firmware setup and review the boot order settings. The settings should be such that the computer boots from the hard drive on which windows is installed on.
If the hard drive is not among the options presented, it is possible that the drive failed or can no longer be used to boot.
Inserting windows recovery media may also help in some of these situations by running the Startup Repair operation. This is a procedure that attempts to make windows bootable by repairing boot sectors errors.
By using the fixboot and fixmbr commands, you can also manually fix problems with Windows boot loader.
Causes of this complication can either be software or hardware related. A startup repair operation will fix most software related problems, and if this fails completely you can reinstall Windows altogether or Reset Windows 8.
Hardware problems are more complex and often recur with no positive response to Startup repair procedures.
Again if this happens or the system crashes during startup, a software or hardware problem could be to blame. Malware and bugs in drivers are common culprits for this, and their presence can be determined by starting Windows in Safe Mode. Uninstalling buggy drivers and software will correct this error. If nothing works, you may have to reinstall Windows or Reset Windows 8.
It is quite infuriating to deal without a computer that does not power up. A competent computer technician, however, will offer a permanent remedy to this problem.
