If your PC is stuck on the Dell screen during startup, it can be frustrating and might indicate an issue with the hardware or software. Here are some steps to help troubleshoot and resolve this problem:

1. Perform a Hard Reset:

   • Turn off your computer completely.
   • Unplug the power cable from the computer.
   • If you're using a laptop, remove the battery (if possible).
   • Wait for about 30 seconds.
   • Reconnect the power cable (or reinsert the battery).
   • Turn on the computer.

2. Boot into Safe Mode:

   • If your computer gets past the Dell logo when in Safe Mode, it may be a software issue causing the problem. To boot into Safe Mode:
     • Turn on your computer.
     • Continuously press the F8 key (or Shift + F8 on some systems) until you see the Advanced Boot Options menu.
     • Select "Safe Mode" from the options.

3. Check for External Devices:

   • Disconnect any external devices (such as USB drives, printers, or external hard drives) that are connected to your computer. Sometimes, a malfunctioning external device can cause boot issues.

4. Run Built-in Diagnostics:

   • Many Dell computers have built-in diagnostics. To run them:
     • Turn off your computer.
     • Turn it back on and immediately start pressing the F12 key repeatedly until the Boot Menu appears.
     • Select "Diagnostics" or "Diagnostic Tools."

5. Check for Disk Errors:

   • A corrupted or failing hard drive can cause boot problems. You can check for disk errors and attempt to repair them:
     • Boot from a Windows installation or recovery disk.
     • Choose the "Repair your computer" option.
     • Select "Troubleshoot" > "Advanced options" > "Command Prompt."
     • Run the command chkdsk /f to check and repair disk errors.

6. Restore BIOS Defaults:

   • Sometimes, incorrect BIOS settings can lead to boot problems. Access the BIOS/UEFI settings by pressing a specific key during startup (usually F2 or Delete) and then restore the default settings.

7. Reinstall or Repair Windows:

   • If none of the above steps resolve the issue, you may need to reinstall or repair your Windows operating system using a Windows installation or recovery disk.

8. Seek Professional Help:

   • If you've tried all the above steps and your PC is still stuck on the Dell screen, it could be a more serious hardware issue. In this case, it's best to contact Dell support or a professional technician for further assistance.

Keep in mind that attempting some of these steps may result in data loss or changes to your system configuration, so proceed with caution. If you're not comfortable performing these troubleshooting steps yourself, it's advisable to seek assistance from a qualified technician or Dell support.
