System Boot Failure - Supermicro X10DRT-B+ User Manual

X10DRT-B+ Motherboard User's Manual
No Video
1. If the power is on, but you do not have video, remove all the add-on cards
and cables.
2. Use the speaker to determine if any beep codes exist. Refer to Appendix A for
details on beep codes. (This option is only available on a motherboard that
has an onboard buzzer/internal speaker installed.)

System Boot Failure

If the system does not display 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 in-
stalled. If there is still no error beep, try to turn on the system again with only
one processor installed in CPU Socket#1. 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 contracting both pads on the CMOS Clear Jumper (JBT1). (Refer to Section
2-8 in Chapter 2.) (This option is available only when there is an internal buzzer
installed on the motherboard.)
2. Remove all components from the motherboard, especially the DIMM mod-
ules. Make sure that the system power is on, and 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.
Losing the System's Setup Configuration
1. Make sure that you are using a high quality power supply. A poor quality
power supply may cause the system to lose the CMOS setup information.
Refer to Section 1-6 for details on recommended power supplies.
2. The battery on your motherboard may be old. Check to verify that it still sup-
plies ~3VDC. If it does not, replace it with a new one.
