Troubleshooting Your Computer
If a network connection responds slowly
If your network connection uses a proxy server, try enabling the option for bypassing
the proxy server for local addresses. You can do this in Control Panel under your
network connection properties.

Memory Problems

If a message says you are out of memory
Make sure drive C is not running low on free space.
If you are having memory problems while running MS-DOS programs, use the
MS-DOS or Application and Software troubleshooter in Windows Help: click Start,
Help and Support (or Help).
Third-party memory cards have not been tested by HP for use with the computer.
Test your computer's memory with the e-Diagtools diagnostics. See "Testing the
Hardware" on page 115.
If memory doesn't increase after adding RAM
Make sure your computer is using only PC2100 DDR-266 or higher memory (RAM)
modules.
If the computer beeps but doesn't start after adding RAM
You installed an incompatible type of RAM. Remove the module.

Modem Problems

If the modem seems slow
Check for excess static or noise on a line reduces the overall transmission speed. If
necessary, contact your telephone company about fixing this type of problem.
If you're dialing internationally, line noise is often a problem that's difficult or
impossible to eliminate.
If you have call-waiting, disable it—your telephone company can provide
instructions. It can cause symptoms similar to static.
