Troubleshooting a new PC build
Start with model compatibility and POST.
Keep the motherboard, processor, RAM and power-supply model numbers together. Consult the motherboard manual for supported components, memory slots and POST indicators. Disconnect power before checking internal connections.
Find your exact error
All Motherboard errors →PCIE-ERROR
Error on the PCIe line between the motherboard and the component. This usually traces back to misplaced card and defective driver.
MotherboardVRM-OVERHEAT
The Voltage Regulator Module is overheating. Limits CPU performance or causes shutdown.
MotherboardPCIE-BIFURCATION-ERROR
The motherboard incorrectly distributes the PCIe lines for the adapter (NVME RAID, PLX switch). It's also often linked to bifurcation disabled in BIOS.
MotherboardCMOS-CHK-ERR
The BIOS has lost its settings due to a dead coin-cell battery on the board. Reports of Corrupt CMOS checksum usually describe a sudden crash, brief unresponsiveness, or a stop-code screen appearing out of nowhere.
MotherboardPOST-CODE-55
The board failed to initialize RAM during boot. The usual suspects are dead battery CR2032, short circuit on the motherboard, aborted BIOS update process and age of capacitors.
MotherboardBIFURC-FAIL
The splitter adapter (eg for multiple M.2 drives) did not get the correct PCIe lines. This usually traces back to dead battery CR2032, short circuit on the motherboard, aborted BIOS update process and age of capacitors.
