Troubleshoot Boot Issues
If you’re unable to reboot your computer using the keyboard, it’s possible you’re experiencing a boot issue. Here are some common troubleshooting tips:
1. Check the Power Supply
Ensure that the computer is securely plugged into a power outlet and that the power cable is not damaged. If necessary, try using a different power outlet.
2. Disconnect Non-Essential Peripherals
Remove any unnecessary peripherals, such as external drives, printers, and USB devices. These devices can sometimes interfere with the boot process.
3. Clear CMOS Settings
The CMOS (Complementary Metal-Oxide-Semiconductor) settings store information about the computer’s hardware configuration, including boot order. Resetting the CMOS can resolve certain boot issues. Refer to your computer’s user manual for instructions on how to perform a CMOS reset.
4. Check the BIOS Settings
The BIOS (Basic Input/Output System) is responsible for initializing the computer’s hardware during boot. Access the BIOS settings and verify that the boot order is correct. Ensure that the hard drive or SSD containing your operating system is set as the primary boot device.
5. Run System Diagnostics
Most computers have built-in diagnostic tools that can help identify hardware issues. Run the system diagnostics and check for any error messages or codes.
6. Consider a System Restore
If other troubleshooting methods fail, you may need to perform a system restore. This will revert your computer to a previous state when it was working properly. System restore points are created automatically by Windows. To perform a system restore, access the Windows Recovery Environment (RE) via the installation disc or a recovery partition, then select “System Restore” from the RE options.
