Checking Inside the Computer 7-1310. Inspect all configuration jumpers on the systemboard to ensure that they are configured correctlyfor any installed expansion cards.For information on the configuration jumpers andtheir settings, see Appendix C, “Jumpers, Switches,and Connectors.”Are the system board’s configuration jumpers setcorrectly?Yes. Go to step 12.No. Continue to step 11.11. Correct the system board’s configuration jumpersettings.Is the problem resolved?Yes. You have fixed the problem.No. Continue to step 12.12. Remove all expansion cards except the hard-diskdrive controller card (if one is installed).See “Removing an Expansion Card” in Chapter 8 forinformation on removing expansion cards.13. Replace the left computer cover, reconnect thesystem to AC power, and turn it on.14. Enter the system setup program and update thesystem configuration information.See Chapter 4, “Using the System Setup Program,”in the system User’s Guide for instructions.For any EISA and ISA expansion cards, enter thesystem configuration utility, and update the con-figuration information.See Chapter 5, “Using the System ConfigurationUtility,” in the system User’s Guide for instructions.15. Run the RAM Test Group in the systemdiagnostics.See Chapter 5, “Running the System Diagnostics.”Do the tests complete successfully?Yes. Continue to step 16.No. See Chapter 11, “Getting Help,” for informationon obtaining technical assistance.16. Turn off the system, disconnect it from AC power,and remove the left computer cover.17. Reinstall one of the expansion cards you removedin step 12, and repeat steps 13 though 15. Then,continue to step 18.18. Repeat steps 16 and 17 for each of the remainingexpansion cards that you removed in step 12.Have you reinstalled all of the expansion cards with-out encountering a test failure?Yes. You have fixed the problem.No. See Chapter 11, “Getting Help,” for informationon obtaining technical assistance.Troubleshooting System MemoryA system memory problem can be a faulty single in-linememory module (SIMM) or a faulty system board. If arandom-access memory (RAM) error message appears,the system probably has a memory problem.When you turn on or reboot the system, the Caps Lockand Scroll Lock indicators on the keyboard should flashmomentarily and then turn off. If the Num Lock categoryin the system setup program is set to On, the Num Lockindicator should flash momentarily and then remain on;otherwise, it should turn off. Abnormal operation of theseindicators can result from a defective SIMM. Followthese steps to troubleshoot system memory:1. Turn on the system, including any attachedperipherals.Does an error message appear indicating invalid sys-tem configuration information after the memorycount completes?Yes. Continue to step 2.No. Go to step 12.2. Enter the system configuration utility to checkthe Extended Memory category and add 1024 kilo-bytes (KB) to the total shown.See Chapter 5, “Using the System ConfigurationUtility,” in the User’s Guide for instructions.Does the amount of memory installed match theExtended Memory setting plus 1024 KB?Yes. Go to step 12.No. Continue to step 3.
