Flash The Asus Bios When The Motherboard Will Not Post

CPU cooler

POST stands for "Power-On Self-Test," which is a built-in utility that scans your hardware and system configuration to confirm that all components are in proper working order. After performing the POST, the computer prepares itself to boot to the operating system. If your ASUS computer fails to run POST at start-up, a loose connection or defective component could be to blame. Alternatively, although it may seem as if the computer won't boot, the system may be attempting to communicate start-up problems via the ASUS Post Reporter, a utility that converts beep codes into voice messages. To enable POST and update your BIOS to the most recent version, perform a few troubleshooting steps to determine the source of the problem.


Use the ASUS POST Reporter

1. Sign on to a different computer and go to the ASUS website (see Resources.) Select your region from the options.

2. Point to "Services," then click "Support." Click "Download." Select your product information from the drop-down menus.

3. Click "Search." Select your ASUS computer's operating system from the drop-down menu, and then click "Search" again.

4. Expand "Manual." Download your computer's documentation from the website. The download usually takes less than a minute on a high-speed Internet connection, but may take several minutes using a dial-up connection. Double-click the file to open it.

5. Review the table of contents to locate the chapter on "Vocal POST Messages" or "ASUS POST Reporter." Print the pages included in the chapter.

6. Connect speakers to the appropriate audio jack located on the rear of the computer. Power on the system to listen for any POST messages. If your ASUS reports a problem, read the instructions in the chapter's "Action" field to resolve the issue.

Troubleshoot the Computer

7. Turn off the computer. Loosen the screws securing the cover to the case, and pop the cover off the case. Touch the chassis to ground yourself.

8. CPU cooler

Locate the CPU fan. The CPU fan is square and is approximately 80 mm to 120 mm in size. A black case houses the fan blades. Power on the computer. If the fan fails to spin, turn off the computer and confirm that the CPU fan cable is connected securely to the motherboard.

9. Disconnect the power cable from the rear of the computer. Confirm that the cable or cables connecting the power supply to the motherboard are secure.

10. Confirm that all of the connections on the motherboard are secure. Check that the CPU, heat sink, expansion cards and memory modules are properly seated and installed.

11. Release the lever securing the coin-shaped CMOS battery in place. Use your fingers to extract the CMOS battery from its slot.

12. Insert the battery into an anti-static bag, and leave it in a safe place overnight to reset the computer's CMOS settings.

13. Reinsert the CMOS battery into its slot. If the computer still fails to POST, the motherboard or power supply may need to be replaced.

Flash the ASUS BIOS

14. Go to the ASUS Support Page (see Resources) and enter your product information. Select your operating system from the drop-down menu.

15. Left-click the "+" next to the "BIOS" category. Click "Global (DLM)." Select a folder to save the file to, and then press "Enter" to download the latest update for your BIOS from the list.

16. Click "Exit" followed by "Start," "Computer" and "Windows Explorer." Go to the folder you saved the file to, and double-click the file to open it. Left-click the first item in the file. Hold down "Shift," and then press "PGDN" to select all of the files shown.
