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. 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 will be one or two 8-pin power connectors
(circled in RED in the pic to the right).
This connector is the main power for the CPU and without
power from the PSU, the system cannot fully power
on and initialize. Depending on your motherboard,
you may have one or two of these connectors; at least
one must be plugged in.
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. If the connectors do not line up, then you
have plugged in a PCI-E 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 fullyseated
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.
