This tab does not appear if the device is not using resources. ❖ The Driver tab, which displays the drivers being used by the device. This tab also provides options for updating the driver or rolling back the driver in case the new version is causing a problem. The tabs that appear in the dialog box vary from one device to another.

Memory problems Incorrectly connected or faulty memory modules may cause errors that seem to be hardware or even software related. It is worthwhile checking for these first: 1 Click Start, and then click the arrow next to the Lock button in the lower-right part of the Start menu. The Shut Down menu appears. 2 Click Shut down. The computer shuts down completely. 3 Remove the memory module, following the instructions in "Removing a memory module" on page 53. 4 Reinstall the memory module, following the instructions in "Installing a memory module" on page 48, and making sure the module is seated properly. 5 Check for the error again. 6 If the error recurs, remove the memory module entirely and check for the error again. If removing the memory module eliminates the error, the memory module may be faulty. If the error recurs without the memory module installed, the error is not caused by the memory module. TECHNICAL NOTE: You must have at least one memory module installed for the computer to work.
