If you have a computer that won’t start up, it can be a frustrating experience. There are a few steps you can take to try and start your computer up again.
1. Check the power source
The first thing you should do if your computer won’t start is check the power source. Make sure all cords are securely plugged in and the power switch is in the ‘on’ position. If your computer has an internal power supply, make sure it’s properly connected. If you can’t figure out where the power source is coming from, seek professional help.
2. Check the monitor
If the power source is in good condition, check the monitor. Make sure the monitor is plugged in and the monitor cable is firmly attached. Power on the monitor and make sure it is receiving a signal from the computer. If the monitor remains blank, test the computer with another monitor or try another video cable.
3. Test the keyboard
If the monitor is working but you don’t get any response from typing on the keyboard, it could be a problem with the keyboard itself. Try using another keyboard, making sure it’s plugged in correctly. If the keyboard works, then the problem may be with the original one.
4. Start up in BIOS mode
The BIOS (Basic Input/Output System) is a set of instructions stored in read-only memory that tell the computer how to start up. To start up your computer in BIOS mode, turn on the computer and press the F10 or Delete key. This will take you to the BIOS setup screen. Go through each option and make sure they are configured properly.
5. Try a different start-up method
If the computer still won’t start, try a different start-up method. The most common method is to press and hold the power button until the computer shuts down, then press it again to restart. You can also try holding down the power button for five seconds to force the computer to shut down and restart.
6. Run a hard drive diagnostic
If none of these methods work, try running a hard drive diagnostic. This process checks the hard drive for any errors or corrupt files that may be causing the computer to fail. To run a hard drive diagnostic, open the computer’s case and look for a diagnostic program preloaded on the hard drive. If there isn’t one, you can download a diagnostic tool from the internet.
7. Replace hardware
If the diagnostic doesn’t reveal any problems, you may need to replace some hardware. Check the RAM, CPU, motherboard, and any other components you think might be causing the problem. If necessary, contact a professional computer technician to help you identify and replace the faulty parts.
8. Reinstall the Operating System
If the hardware replacement doesn’t work, you may need to reinstall the operating system. This process erases all the data on the hard drive and reinstalls the system software. You will need to use a bootable CD or USB stick to reinstall the system.
9. Seek professional help
If none of these solutions work, it may indicate a more serious problem. In this case, you may need to take your computer to a professional repair shop for help. They will be able to diagnose the problem and suggest a solution.
With these steps, you should be able to solve most problems that cause your computer to not start up. However, if the problem persists, you should seek professional help.
