2-3.8 Troubleshooting at First Start
l What should I do if the Motherboard refuses to start?
1. Check that all DIMM memory modules are inserted completely.
Sometimes a DIMM that is not inserted properly can cause boot
problems.
2. Check whether all Add-on cards have been inserted properly. Re-
insert the Add-on cards to make sure that they make proper contact
with the slots. Try removing all Add-on cards one by one to see
whether or not one of them is causing problems. (Switch the system
off before removing any of the cards.
3. Verify that speed settings are not exceeding specifications. This
applies to the PCI bus, that is specified to run at 33 MHz. Also check
the speed setting for the memory, make sure conservative setting is
used. If the CPU is overclocked the system may not start up, read the
section below.
4. Make sure that the Harddisk IDE cables are attached properly, if not
the system will not boot. In case of doubt try reversing the IDE
connector on one end of the cable.
5. Verify that the 110/220V switch on the back of the power supply is
set correctly.
6. Go through the jumper setting section again to make sure that all
jumpers are set correctly.
Note on Over-clocking Capability
The SY-6BA+ IV provides over-clocking capability. Due to the over-
clocking setting your system may fail to boot up or hang during run time.
Please perform the following steps to recover your system from the
abnormal situation :
1. Turn off system power (If you use an ATX power supply, and
depending on your system, you may have to press the power button
for more than 4 seconds to shut down the system.)
