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 “C,” 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 “C”, as well. It is not likely a faulty CPU,
although it is possible; instead, it is most likely a CPU
power issue. Above the CPU socket, there are two 8-
pin power connectors (each outlined in white 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 one of these connectors must be plugged in; both
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 boxes
in white in the image below 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.
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.
