Troubleshooting
Often after time spent troubleshooting, the problem is traced to something as simple as a loose
connection. Check the following before proceeding to the problem-specific solutions.
The Power-On Self Test
The Power-On Self Test (POST) runs every time you turn on or reset the computer. The
POST checks memory, the mainboard, the display, the keyboard, the disk drives, and other
installed options.
If failure is detected in an area other than the mainboard (such as the keyboard or an adapter
card), an error message is displayed on the screen and testing is stopped.
If your system does not successfully complete the POST, but displays a blank screen, have the
Anypos serviced.
Beep Errors at POST
There are two kinds of beep codes in the BIOS.
＊Video error - a single long beep followed by three short beeps indicates a video error, the
screen can not be initialized and no information can be displayed.
＊DRAM error - a single long beep indicates that a DRAM error has occurred.
Beep Message Errors at POST
If the BIOS detects an error during the POST, a message is displayed. Refer to the following
table for a list of the errors that display.
