1Determine if a conflict exists by

removing a card (see page92) (not

the video card) and then restarting

the computer.

the card that you removed (see

page88), remove a different card,

and then restart the computer.

3Repeat this process for each card.

If the computer starts normally,

troubleshoot the last card removed

from the computer for resource

conflicts (see "Resolving Software

and Hardware Incompatibilities"

on page70) .

4If the problem persists, contact

Dell (see page120).
