No Video
1. If the power is on, but you have no video, remove all add-on cards and cables.
2. Use the speaker to determine if any beep codes are present. Refer to Appendix A for
details on beep codes.
3. Remove all memory modules and turn on the system (if the alarm is on, check the
specs of memory modules, reset the memory or try a different one).
System Boot Failure
If the system does not display Power-On-Self-Test (POST) or does not respond after the
power is turned on, check the following:
1. Check for any error beep from the motherboard speaker.
•
If there is no error beep, try to turn on the system without DIMM modules installed. If there
is still no error beep, replace the motherboard.
•
If there are error beeps, clear the CMOS settings by unplugging the power cord and con-
tacting both pads on the CMOS clear jumper (JBT1). Refer to Section 2-8 in Chapter 2.
2. Remove all components from the motherboard, especially the DIMM modules. Make
sure that system power is on and that memory error beeps are activated.
3. Turn on the system with only one DIMM module installed. If the system boots, check for
bad DIMM modules or slots by following the Memory Errors Troubleshooting procedure
in this chapter.
Memory Errors
When a no-memory beep code is issued by the system, check the following:
1. Make sure that the memory modules are compatible with the system and are properly
installed. See Chapter 2 for installation instructions. (For memory compatibility, refer
to the "Tested Memory List" link on the motherboard's product page to see a list of
supported memory.)
2. Check if different speeds of DIMMs have been installed. It is strongly recommended that
you use the same RAM type and speed for all DIMMs in the system.
3. Make sure that you are using the correct type of ECC DDR4 modules recommended by
the manufacturer.
4. Check for bad DIMM modules or slots by swapping a single module among all memory
slots and check the results.
