USB 2.0 Flash Drive (FAT32 Formatted)
The Z790 chipset often requires a BIOS update to support Intel 14th Gen 'Raptor Lake Refresh' CPUs. This drive allows for the use of the 'Flash BIOS Button' to update the UEFI firmware microcode, which is necessary for the motherboard to recognize the CPU ID and proceed past the initial logic check indicated by the red LED.

MSI MAG Z790 Tomahawk WiFi Motherboard
If firmware updates do not resolve the issue, the failure is likely mechanical within the LGA 1700 socket. Even slight misalignment of the 1,700 pins prevents signal integrity for the VCC or data bus pins, halting the boot process before the motherboard can initialize the memory or video subsystems.

EPS12V 8-Pin CPU Power Cable
The CPU debug LED will trigger if the processor's dedicated VRM (Voltage Regulator Module) does not receive sufficient power. A failure in the cable's latching mechanism or a pin-out mismatch from the power supply prevents the 'Power Good' signal from being asserted to the CPU.
