System does not POST, and POST code
indicator reads “C”
When the system powers on, the POST code indicator should cycle through several
different codes before booting. However, if the boot process does not complete, you
should look at the LED indicator, as it will give you diagnostic information. When a
POST code indicator cycles through codes and stops at a specific code, this is an
indication that initialization of a specific component or process on the board failed. If
you power on the board and it goes directly to “
00
,” and nothing
else, that is an indication of a CPU-related issue. If the board
cannot detect the CPU in the socket, the POST code display will
display a “
00
”, as well.
It is not likely a faulty CPU, although it is
possible; instead, it is most likely a CPU power issue. To the
right of the CPU socket, there are four 8-pin power connectors
(outlined in
BLUE
in the image to the right). These connectors
are the main power for the CPU, and without power from the
PSU the system cannot fully power on and initialize; at least two
must be plugged in. All of these connectors are equivalent.
Make sure the plug is fully-seated and also make sure that the tab
on the socket and the release on the power connector are on the
same side (see the box in
BLUE
on the second picture for the
tab on the EPS connector). If the connectors do not line up, then you have plugged in a
PCIe 8-pin into the EPS connector, which may cause irreparable damage to the
motherboard or the CPU.
For the SR-3 DARK,
attempting to plug in an 8-pin
PCIe plug will likely damage
the motherboard’s PCB due
to the right-angle connectors.
If the PSU is modular, make sure the cable is fully-seated on the PSU side, as well. Also,
only use cables from your PSU manufacturer for your specific PSU, because using a
cable designed for a different PSU may have catastrophic effects. Finally, ensure that
the cable on the PSU side is plugged into the connector for the CPU, typically labelled
“CPU” or “EPS,” but consult your power supply manual for the correct plug
.
