Troubleshooting No POST and No Boot Problems
If your Dell computer won’t start or boot, there are a few troubleshooting steps you can follow to resolve the issue.
First, check the power connections and ensure that the power strip or outlet is functioning properly. If the power is on, but the computer is still not starting, try a hard reset. Disconnect all peripherals, including the power cord, and hold down the power button for 15 seconds. Then, reconnect the power cord and try turning on the computer again.
If the problem persists, it could be related to the hard disk drive (HDD) or the operating system (Windows 10). Use the Dell diagnostics tool to check the HDD for any errors and consider reinstalling Windows 10 if necessary.
If you’re using a Dell monitor, ensure that it is properly connected and powered on. If the screen remains blank, try connecting your computer to an external monitor to determine if the issue is with the monitor or the computer itself.
