Memory errors might stop system operations, show error messages on the screen, or hang the system.
Use the following procedure to isolate memory problems.
Note:
Make sure that the memory card is fully installed into the connector. Loose connections can cause errors.
1. Power-off the computer and remove the IC DRAM card from its slot (if installed).
2. Press and hold the F1 key; then power-on the computer. Hold the F1 key down until the Easy-Setup screen appears.
3. Select Test and press enter.
4. Select Memory and press enter to run the memory test on base memory. If an error appears, replace the system board.
5. Power-off the computer and reinstall the IC DRAM card; then power-on the computer. Verify the memory size; then test the memory. If an error appears, replace the IC DRAM card.
If memory problems occur intermittently, use the loop option to repeat the test.
When the test detects an error, an error log is printed on the printer connected to the parallel port. See żError Log— for more information.
