X10DRH-C/CT/i/iT Motherboard User’s Manual

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 Ap-

pendix A for details on beep codes.

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 contacting both pads on the CMOS Clear Jumper (JBT1). (Refer to the

Jumper section in Chapter 2.)

2. Remove all components from the motherboard, especially the DIMM mod-

ules. 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.

Losing the System’s Setup Conguration

1. Make sure that you are using a high-quality power supply. A poor-quality pow-

er supply may cause the system to lose the CMOS setup information. Refer

to the Connecting Cables section 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.

3. If the above steps do not x the setup conguration problem, contact your

vendor for repairs.
