Using System Information

System Information is a Windows XP tool that can give you a lot information about your system’s configuration and the software installed. First introduced in Windows 98, System Information is a powerful tool that includes some additional tools that can fix problems on your system, as you can see in Figure 16-1. You can open System Information by clicking Start | All Programs | Accessories | System Tools, or you can more simply type MSINFO32 in the Run line. Either way, System Information, which is actually a part of the Help and Support Center, opens.

Figure 16-1: System Information

If you take a look at the left pane, you see a list of information categories. If you click the plus sign (+) next to each category, you can select specific topics for which you want to gather information. You cannot use System Information to actually configure or “do” anything, unless you use its troubleshooting tools. Instead, System Information is designed to give you information that can help you troubleshoot a problem. On a more practical note, System Information is very useful for telephoning support personnel who you may need to call in the event of a problem you can’t solve. Of course, it is always best if you can solve your own PC problems, so the next several sections tell you all about the information you can gain in each major category, and I’ll point out some tips for you along the way.

System Summary

When you first open System Information, the default view is the System Summary. This view just gives you an overview of your computer. You see everything from the operating system to the total amount of RAM installed on your computer. This page is excellent to access if you want a quick report about the basics found on your computer. You can easily print this page as well.

Hardware Resources

The Hardware Resources category of System Information gives you a complete look at the hardware on your computer. This section, shown in Figure 16-2, is an excellent way to see exactly what is installed, what’s working and what’s not, and whether there are any conflicts.

Should there be any conflicts, you’ll see warning messages in yellow and conflict or error messages in red. This helps you quickly identify problems if they exist. By expanding Hardware Resources in the left pane, you see the following categories that you can select and view:

  • Conflicts/Sharing  This option tells whether there are any hardware conflicts between devices. In some cases, hardware devices share certain computer resources, and this section tells you about those as well.

  • DMA (Direct Memory Access)  This option tells you what devices have direct access to memory resources.

  • Forced Hardware  If you have problems installing a device and it has been “forced” onto your system using manual settings, the device will be listed here.

  • I/O (Input/Output System)  This category reports information about input/output operations. Technical support personnel may find this information useful.

  • IRQs (Interrupt Request Lines)  Each device uses an IRQ to access your computer’s processor. This category tells you which device is using which IRQ.

  • Memory  This category provides a list of memory resource assignment per device.

Components

The Components category provides a list of components installed and used on your system. Some of the component options listed here have additional pop-out menus as well, as shown in Figure 16-3. As a reminder, System Information will display problems in yellow and red lettering so you can easily identify them.

  • OLE (Object Linking and Embedding) Registration   Windows XP uses OLE so that various system components and programs can communicate with each other. OLE information is listed here.

  • Windows Error Reporting  This section provides a listing of software errors reported by the system.

Note 

The Windows Error Reporting section, which is new in Windows XP, is a great feature because it lists all of the application lock-ups and related service problems. If you are having trouble, this can be a great place to find the culprit!

Internet Settings

The Internet Settings category, shown in Figure 16-5, provides you information about the configuration of Internet Explorer.

  • Content  Examine security and content settings here.

  • Security  View the zone security configuration here.

Applications

Any applications that are installed on your computer are listed in the Applications category. Click the plus sign (+) next to each listed application to learn about configuration specific to that application. This is a useful option to find out about problems and conflicts with any installed applications.

Note 

If you are having problems finding the information that you need, try the Find What quick search utility that appears at the bottom of the System Information window.

System Information Tools

System Information also gives you a Tools menu that provides easy access to some features and tools in Windows XP. If you check out this menu, you see right away that you can access the Backup tool, the Network Connections folder, the Hardware Wizard, and a Disk Cleanup utility. However, you can also access three additional tools not yet discussed in this book, and the next three sections explore these tools and show you how they can help you.

File Signature Verification Utility

To protect and ensure Windows XP’s compatibility and security, Microsoft signs files that the operation system uses. You can use the Signature Verification Utility, shown here, to make certain that no unsigned files are in use on your system.

click to expand

By default, Windows XP displays a warning message before you install unsigned files. You can use this tool to gather information about any unsigned files on your system. When you open Signature Verification, just click the Start button to run the verification scan.

Once the scan is complete, you see a report showing all of the unsigned files on your system. Generally, you shouldn’t have to use this tool. However, if you have installed some programs on your computer that are giving you problems, you can run this utility to check for signatures. If you need to use the tool, you can specify a few options by clicking the Advanced button. This opens an Advanced properties dialog box, which includes a Search tab and a Logging tab.

On the Search tab, shown in Figure 16-6, you can specify search parameters to look for system or other files that are not signed. For example, if you want to look for all .DLL files that are not signed, you can perform that search here. You can also choose to search in a particular folder.


Figure 16-6: Search tab

On the Logging tab, shown in Figure 16-7, you can choose to log the results of the scan. With each scan, you can either append the data to the existing log or overwrite the log each time. By default, the log file is named sigverif.txt.

DirectX Diagnostic Tool

DirectX is a graphics technology that enables you to play three-dimensional (3-D) games and use other multimedia software. However, you can have problems with various versions of DirectX and its operation with your system components. The DirectX Diagnostic Tool gives you an easy interface with a bunch of tabs, shown in Figure 16-8.

Figure 16-8: Use the DirectX Diagnostic Tool to solve compatibility problems with DirectX

The DirectX files, media files, and drivers tabs of this tool report a variety of information to you. The Display, Sound, Music, Input, and Network tabs give you information about how DirectX is interacting with these system resources. Each of these tabs also contains a test button so you can directly test how DirectX is interacting with the hardware. This is a great tool that can help you identify exactly what incompatibilities are occurring with DirectX and your hardware.

Dr. Watson

Dr. Watson is a Windows tool that can inspect your system and generate a detailed report after a system fault has occurred. Dr. Watson can tell you what went wrong and sometimes suggest what can be done to fix the problem. Should you ever need to contact technical support, the staff may have you run Dr. Watson in order to take a “snapshot” of your system. Once the snapshot is taken, the report may be helpful in solving the problem.

Note 

You can run this tool yourself, of course. The results are usually easy to understand. If you see a particular application or device listed, you may need to retry reinstalling the application or device in question—or just remove it from Windows XP altogether.
