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 is
one 8-pin power connector (as shown in the image 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.
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 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.
The Z490 FTW also features a 4-pin ATX power connector. This connector is
provided as an optional connection to provide supplemental power, but should not be
used as the main power source for the CPU. If you are unable to POST, make sure that
you have first plugged in the 8-pin EPS connector.
