1. Verify the Computer Finishes Initial Power-Up (POST)
In many cases, a computer will not attempt to hand off control to the operating system. If you power the computer on and you see a Dell logo screen with a bar at the bottom, and that bar fills up completely and disappears, then your computer has successfully completed POST.
2. Unplug All External Devices
A piece of hardware may be interfering with the normal boot process of Windows. Try unplugging all devices from your computer, including:
- Printers
- Scanners
- Media Card Readers
- Small Media cradles (iPod, PDA, MP3 player, etc.)
- Digital Cameras and Video Recorders
- USB storage devices
- CDs or DVDs from all optical drives
- Docking station
The only devices you should leave attached to your computer are your monitor, mouse and keyboard if the computer is a desktop.
Once this is completed, unplug the computer from the wall, remove the laptop battery (if applicable) and hold the power button down for approximately 15 seconds. Then plug wall power back into the computer and attempt to restart.
3. Check for Specific Error Messages
Dell has information on some specific error messages at startup. Refer to the following links for more information:
- Loading PBR for Descriptor generated after POST
- A BLUE SCREEN or STOP error has occurred
If the error message is not listed above, try searching for additional solutions on the Web.
