The following troubleshooting methods are provided to help resolve boot issues following installation of new hardware or software.

If you upgraded the processor

Check the Intel® Processors and Boards Compatibility Tool to be sure the new processor is compatible with your board. This tool will also show if the new processor requires a specific desktop board version or a specific BIOS version.

If you added or changed memory modules

Make sure the new memory modules are supported for your desktop board. To find the tested memory list for your board, go to Tested Memory.

If you installed a new add-in card in a PCI or PCI Express* slot

  • Some PCI Express graphics cards require more power.
  • Remove and reinstall the new card to make sure it is fully seated in the slot.
  • Try the card in a different slot, if possible.
  • Make sure other devices and cables inside the chassis were not disturbed or loosened when you installed the new card.

If you added a new drive (hard drive, CD-ROM, DVD)

  • Make sure all drive cables are properly connected.
  • Make sure the correct power cable is connected to the new drive.
  • Make sure any drive jumpers (master, slave) are configured correctly according to the manufacturer.
  • Make sure other devices and cables inside the chassis were not disturbed or loosened when you added the new drive.

If you installed new software or new device drivers

Try booting into Safe Mode and uninstall the new software or driver. If you can boot normally, a compatibility issue might exist between the new software or driver and some component in your system. Contact the software manufacturer for assistance.
