Technical Information in C#

Creation Data Matrix in C# Technical Information

The Technical Information section lists the Stop error number, also known as the bugcheck code, followed by up to four Stop error specific codes (displayed as hexadecimal numbers enclosed in parentheses), which identify related parameters . Stop error codes contain a 0x prefix, which indicates that the number is in hexadecimal format . For example, in Figure 32-1, the Stop error hexadecimal code is 0x000000FE (often written as 0xFE) .

The Driver Information section identifies the driver associated with the Stop error . If a file is specified by name, you can use safe mode to verify that the driver is signed or has a date stamp that coincides with other drivers . If necessary, you can replace the file manually (in Startup Repair or in safe mode) or use Roll Back Driver to revert to a previous version . For more information about Startup Repair and safe mode, see 29, Configuring Startup and Troubleshooting Startup Issues . For more information about troubleshooting drivers, see 30, Troubleshooting Hardware, Driver, and Disk Issues . Figure 32-1 does not display a driver name .

The Debug Port and Dump Status Information section lists Component Object Model (COM) port parameters that a kernel debugger uses, if enabled . If you have enabled memory dump file saves, this section also indicates whether one was successfully written . As a dump file is being written to the disk, the percentage shown after Dumping physical memory to disk is incremented to 100 . A value of 100 indicates that the memory dump was successfully saved . For more information about installing and using kernel debuggers, see the section titled Using Symbol Files and Debuggers later in this chapter .

A hardware or software problem can cause a Stop error, which causes a Stop message to appear . Stop messages typically fit into one of the following categories:

Stop errors caused by faulty software A Stop error can occur when a driver, service, or system feature running in Kernel mode introduces an exception . For example, a driver attempts to perform an operation above its assigned interrupt request level (IRQL) or tries to write to an invalid memory address . A Stop message might seem to appear randomly, but through careful observation, you might be able to associate the problem with a specific activity . Verify that all installed software (especially drivers) in question is fully Windows 7 compatible and that you are running the latest versions . Windows 7 compatibility is especially important for applications that might install drivers . Stop errors caused by hardware issues This problem occurs as an unplanned event resulting from defective, malfunctioning, or incorrectly configured hardware . If you suspect a Stop error is caused by hardware, first install the latest drivers for that hardware . Failing hardware can cause Stop errors regardless of the stability of the driver, however . For more information about how to troubleshoot hardware issues, see 30 . Executive initialization Stop errors Executive initialization Stop errors occur only during the relatively short Windows executive initialization sequence . Typically, these Stop errors are caused by corrupted system files or faulty hardware . To resolve them,

run Startup Repair as described in 29 . If problems persist, verify that all hardware features have the latest firmware and then continue troubleshooting as described in 30 .

Installation Stop errors that occur during setup For new installations, installation Stop errors typically occur because of incompatible hardware, defective hardware, or outdated firmware . During an operating system upgrade, Stop errors can occur when incompatible applications and drivers exist on the system . Update the computer s firmware to the version recommended by the computer manufacturer before installing Windows . Consult your system documentation for information about checking and upgrading your computer s firmware .
