General hardware problems If your computer exhibits one or more of the following symptoms, a device conflict may exist: Your computer locks up, particularly while using a specific device. A recently added device does not work. Memory parity errors occur on parity-enabled computers. A sound card emits noise or demonstrates other problems. Unintelligible characters print from the printer. The mouse pointer does not move or "stutters" when it moves.
If you receive an insufficient memory message Save and close any open files and exit any open programs you are not using to see if that resolves the problem. Confirm that the computer has sufficient memory to run your programs. See the documentation that came with the software for minimum memory requirements. If necessary, install additional memory (see "Memory" for module installation procedures). Reseat the memory modules to ensure that your computer is successfully communicating with the memory.
Check the network cable connector— Ensure that the network cable is firmly inserted into both the network connector on the back of the computer and the network jack. Check the network lights on the back of the computer— No light indicates there is no network communication. Try replacing the network cable.
Ensure that the microprocessor power cable is securely connected to the system board. Ensure that the power supply cables are securely connected to the system board (see "System Board Components"). If the problem persists, contact Dell. If the power light is blinking amber— A device might be malfunctioning or might be incorrectly installed.

Windows XP features a redesigned user interface with a new visual style, a less cluttered desktop, and built-in desktop cleanup features. Window layout has also been changed for Windows XP and, as in the Control Panel, emphasizes task presentation. The Start menu has been redesigned. The left half of the new Start menu includes the most frequently used icons. As you use your computer, the icons in this area are changed and rearranged depending on your computer usage patterns.

The shortcuts are moved to the folder C:\Desktop Icons. To access desktop icons removed by Windows XP, click the Start button, and then click Dell Solution Center.
Application and Device Compatibility Although Windows XP is designed to be compatible with a wide range of application programs and hardware devices, some older programs and devices may not be usable. Check the Microsoft website at www.microsoft.com for application programs and hardware devices known to be compatible.

If you encounter operating system problems, you can use the System Restore feature to select any of the restore points presented through the System Restore Wizard.
3. Click the Hardware tab, and then click Device Manager. 4. In the Device Manager window, right-click the device for which the new driver was installed, and then click Properties. 5. Click the Drivers tab, and then click Roll Back Driver. User Accounts and Fast User Switching NOTE: Fast User Switching is the default user screen for both Home and Professional editions, but it is disabled in Windows XP Professional when the computer is a member of a computer domain.
DVD software shuts down and requires a restart when the user comes back. Computers with low memory configurations can experience problems. The computer uses memory to keep the first user's programs running in the background while the second user is logged on. On computers with limited memory, this can cause the entire computer to run slowly. Fast User Switching is off by default on computers with less than 128 megabytes (MB) of random-access memory (RAM).
Home and Small Office Networking The Network Setup Wizard includes a checklist and steps to guide you through the process of sharing resources, such as files, printers, or an Internet connection, between computers in a home or small office. In Windows XP, Microsoft has improved the online documentation and usability of operating-system tools for setting up a home or small office network.
