Check for Non-Default Hardware Clock Speeds in Visual C#.NET

Encode Data Matrix 2d barcode in Visual C#.NET Check for Non-Default Hardware Clock Speeds

Verify that the hardware is running at the correct speed . Do not set clock speeds for features such as the processor, video adapter, or memory above the rated specification (overclocking) . This can cause random errors that are difficult to diagnose . If you are experiencing problems with overclocked hardware, restore default clock speed and CPU voltage settings according to the instructions provided by the hardware manufacturer .

Check the manufacturer s Web site to see if updated firmware is available for your system or individual peripherals .

Run hardware diagnostic software to verify that your hardware is not defective . These tools are typically built into or bundled with your hardware .

If your system uses ATA storage devices such as hard disks, determine whether the firmware setting Primary IDE Only is available . If the setting is available, enable it if the second ATA channel is unused . Verify that primary and secondary device jumper settings are set correctly . Storage devices (including CD and DVD-ROM drives) use their own firmware, so check the manufacturer s Web site periodically for updates . Verify that you are using a cable that is compatible with your device certain ATA standards require that you use a different cable type .

If your system uses an SCSI adapter, check for updates to device drivers and adapter firmware . Try disabling advanced SCSI firmware options, such as sync negotiation for low-bandwidth devices (tape drives and CD-ROM drives) . Verify that you are using cables that meet the SCSI adapter s requirements for termination and maximum cable length . Check SCSI ID settings and termination to ensure that they are correct for all devices . For more information, see 30 .

Verify that internal expansion boards and external devices are firmly seated and properly installed and that connecting cables are properly fastened . If necessary, clean adapter card electrical contacts using supplies available at electronics stores . For more information about troubleshooting hardware, see 30 .

If a Stop message appears immediately after you add new memory, verify that the new part is compatible with your system . Do not rely solely on physical characteristics (such as chip count or module dimensions) when purchasing new or replacement memory . Always adhere to the manufacturer s specifications when purchasing memory modules . For example, you can fit a memory module rated for 66-megahertz (MHz) or 100-MHz operation (PC66 or PC100 RAM, respectively) into a system using a 132-Mhz memory bus speed, and it might initially appear to work . However, using the slower memory results in system instability . To test memory, use Windows Memory Diagnostics, as described in 30 .

Installing a new device can sometimes cause resource conflicts with existing devices . You might recover from this problem by temporarily removing devices not needed to start the operating system . For example, temporarily removing a CD-ROM or audio adapter might allow you to start Windows . You can then examine the device and operating system settings separately to determine what changes you need to make . For more information about simplifying your hardware configuration for troubleshooting purposes, see 29 .

If you are unable to obtain diagnostic software for the problem device, install a replacement to verify that this action resolves the problem . If the problem disappears, the original hardware might be defective or incorrectly configured .

You might be able to find information about a workaround or solution to the problem . Information sources include the Knowledge Base and the manufacturer s technical support Web page .
