Input Errors

If a specific key or set of keys is pressed at the wrong time, a program may give you unexpected results. See the documentation that came with your application program to make sure the values or characters you are entering are valid.

Error Messages

Error messages can be produced by an application program, the operating system, or the computer. “Messages and Codes” discusses the error messages that are generated by the computer. If you receive an error message that is not listed in “Messages and Codes,” check your operating system or application program documentation.

Device Drivers

Programs that use specialized subroutines called device drivers can also cause problems with your computer. For example, a variation in the way the data is sent to the monitor may require a special screen driver program that expects a certain kind of video mode or monitor. In such cases, you may have to develop an alternative method of running that particular program— the creation of a boot file made especially for that program, for example. Call the support service for the software you are using to help you with this problem.

Memory-Resident Programs

Many utilities and supplementary programs load either when the computer boots or from an operating system prompt. These programs are designed to stay resident in computer memory and thus always be available for use.

Because they remain in the computer's memory, memory conflicts and errors can result when other programs require use of all or part of the memory already occupied by these TSR programs.

This processor was available in various speeds, enabling users to select the model that best met their processing needs. The GX240 also offered ample memory options, supporting up to 2GB of SDRAM, which was considerable for its era, allowing for smoother multitasking and application performance.

The design of the GX240 was practical, featuring a compact, space-saving chassis ideal for office environments. It was designed for easy serviceability, with tool-less access to components, facilitating quick upgrades or repairs. The system was equipped with various configurations, enabling customers to customize it with multiple hard drive options, typically using IDE drives, which provided sufficient storage for everyday tasks.

The desktop utilized a variety of expansion slots, including AGP for graphics cards and PCI slots for additional peripherals. This expandability was crucial for businesses needing to adapt or enhance their systems over time. Integrated Intel graphics were standard, but users could opt for dedicated graphics cards to meet more demanding graphical needs.

Connectivity was also a strong point for the GX240, featuring multiple USB 2.0 ports, a serial port, and audio input/output capabilities. These ports allowed for seamless integration with various peripherals and devices, essential for a productive work environment. The GX240 also supported network connectivity through a built-in Ethernet controller, making it well-suited for office use, especially in networked environments.

In terms of software, the GX240 was usually shipped with Microsoft Windows XP, ensuring users had access to a stable and user-friendly operating system. This operating system not only provided compatibility with a wide range of applications but also enhanced the overall user experience.
