Before You Begin - Dell PowerEdge 4300 Installation And Troubleshooting Manual

13. Run the RAM test group in the Dell Diagnostics.
See Chapter 5, "Running the Dell Diagnostics."
Did the tests run successfully?
Yes. You have fixed the problem.
No. See Chapter 11, "Getting Help," for instructions on obtaining technical
assistance.
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" in Chapter 6 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" found earlier in this chapter 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 Chapter 5, "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 Chapter 4, "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.
3. Remove the computer cover.
See "Removing the Computer Cover" found earlier in this chapter.
