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 the monitor is the source of the problem.
If you have a
Follow these steps to troubleshoot the video subsystem:
1.Run the Video Test Group in the system diagnostics.
See Chapter 5, “Running the System Diagnostics.”
Most of the tests in the Video Test Group are inter- active; that is, you must respond before the diagnostics continues with the next test.
Do the tests complete successfully?
Yes. It is not a video hardware problem. Go to Chap- ter 4, “Finding Software Solutions.”
No. Continue to step 2.
2.Turn off the system, including any attached peripherals, and disconnect all the AC power cables from their power sources.
3.Remove the left computer cover.
See “Removing the Computer Covers” earlier in this chapter.
CAUTION: See “Protecting Against Electro- static Discharge” in the safety instructions at the front of this guide.
4.Determine whether a video expansion card is installed.
Is a video expansion card installed? Yes. Continue to step 5.
No. The
5.Remove the video expansion card, and repeat step 1.
Do the tests complete successfully?
Yes. The video expansion card is faulty. See Chap- ter 11, “Getting Help,” for instructions on obtaining technical assistance.
No. Continue to step 6.
6.See Chapter 11, “Getting Help,” for instructions on obtaining technical assistance.
Troubleshooting the System Board
A system board problem can result from a defective sys- tem board component, a faulty power supply, or a defective component connected to the system board. If an error message indicates a system board problem, follow these steps to find the problem:
1.Turn off the system, including any attached peripherals, and disconnect all the AC power cables from their power sources.
2.Remove the left computer cover.
See “Removing the Computer Covers” earlier in this chapter.
CAUTION: See “Protecting Against Electro- static Discharge” in the safety instructions at the front of this guide.
3.Remove all expansion cards except the
4.Replace the left computer cover, reconnect the system to AC power, and turn it on.
5.For any EISA and ISA expansion cards, start the system configuration utility, and update the con- figuration information.
See Chapter 5, “Using the System Configuration Utility,” in the system User’s Guide for instructions.
