Troubleshooting the Video Subsystem
Troubleshooting video problems involves determining which of the following is the source of the problem: the monitor,
the monitor interface cable, the video memory, or the video logic of the computer. You can also have a high-resolution
video expansion card installed, which overrides the video logic of the computer.
The following procedure troubleshoots problems with the video memory and video logic only. Before you begin,
perform the procedure found in Troubleshooting the Monitor to determine whether or not the monitor is the source of
the problem.
If you have a high-resolution video expansion card, first complete the steps in Troubleshooting Expansion Cards to
verify that the card is configured and installed correctly.
Follow these steps to troubleshoot the video subsystem:
1. Run the Video test group in the Dell Diagnostics.
See Running the Dell Diagnostics.
Most of the tests in the Video test group are interactive; that is, you must respond before the diagnostics
continues with the next test.
Did the tests run successfully?
Yes. It is not a video hardware problem. Go to Finding Software Solutions.
No. Go to step 2.
2. Turn off the system, including any attached peripherals, and disconnect the power cable from the electrical outlet.
CAUTION: See Protecting Against Electrostatic Discharge in the Safety Instructions.
3. Remove the computer cover.
See Removing the Computer Cover.
4. Determine whether a video expansion card is installed.
Is a video expansion card installed?
Yes. Go to step 5.
No. The integrated video controller is faulty. See Getting Help for instructions on obtaining technical assistance.
