If the computer starts normally, troubleshoot the last card removed from the computer for resource conflicts (see "Resolving Software and Hardware Incompatibilities" on page 49). 4 If the problem persists, contact Dell (see page 90). • Ensure that the cables are properly connected from the hard drive, CD drive, and DVD drive to the system board (see page 70). • If the problem persists, contact Dell (see page 90). 42 Advanced Troubleshooting
