Motherboard errors
31 errors. Choose the message that matches your computer.
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.
MotherboardSEC-BOT-KEY-MS
Safe boot platform keys deleted, can't boot into Windows 11. The usual suspects are dead battery CR2032, short circuit on the motherboard, aborted BIOS update process and age of capacitors.
MotherboardTPM-ATT-FAIL
The Trusted Platform Module failed to verify the identity of the hardware. It's most often caused by dead battery CR2032, short circuit on the motherboard, aborted BIOS update process and age of capacitors.
MotherboardVRM-PHS-IMB
One of the power supply phases on the board does not supply current, the others are critically overloaded. The usual suspects are dead battery CR2032, short circuit on the motherboard, aborted BIOS update process and…
MotherboardUSB-CTL-DEAD
Some or all of the USB ports have completely stopped responding, the mouse and keyboard are not working. Common triggers are dead battery CR2032, short circuit on the motherboard, aborted BIOS update process and age…
MotherboardPCH-OVERHEAT
The chipset on the board is overheating because the passive cooling has lost contact. Common triggers are dead battery CR2032, short circuit on the motherboard, aborted BIOS update process and age of capacitors.
MotherboardAZA-AUD-MISS
The integrated sound card (eg Realtek) completely disappeared from the device manager. Typical causes include dead battery CR2032, short circuit on the motherboard, aborted BIOS update process and age of capacitors.
MotherboardBIOS-FLS-FAIL
A corrupt installation file was detected while attempting to update the BIOS. The usual suspects are dead battery CR2032, short circuit on the motherboard and age of capacitors.
MotherboardDMI-LNK-DOWN
Communication between the processor and the rest of the board collapses. Common triggers are dead battery CR2032, short circuit on the motherboard and age of capacitors.
MotherboardCMOS-BAT-LEAK
Physical damage to the board caused by button cell battery acid. Typical causes include short circuit on the motherboard, aborted BIOS update process and age of capacitors.
MotherboardARGB-HDR-SHRT
The motherboard has shorted on the 5V ARGB connector, the lighting is flashing or off. It's most often caused by dead battery CR2032, aborted BIOS update process and age of capacitors.
MotherboardLPC-BUS-HANG
The sensor bus for temperature monitoring and fan control stopped responding. The usual suspects are dead battery CR2032, short circuit on the motherboard, aborted BIOS update process and age of capacitors.
MotherboardFAN-HDR-BURN
Connecting a too powerful fan fried the PWM control circuit on the motherboard. Common triggers are dead battery CR2032, aborted BIOS update process and age of capacitors.
MotherboardUSB-DEV-DESC-FAIL
When connecting a USB device, the system failed to read its identifier and reports error code 43. This can also stem from bad USB controller on board.
MotherboardBT-ERR-43
Bluetooth has stopped working, the icon has disappeared and the device is reporting Code 43. Common triggers are chip firmware (Intel/Realtek) stuck due to static electricity and outdated Driver.
MotherboardBATT-NOT-CHARGING
The adapter is on the network, the icon shows power, but the percentages do not increase. Common triggers are damaged battery (wear), manufacturer's battery software block (life extension - Lenovo Vantage, Asus…
MotherboardUSB-POWER-SURGE
The USB device has exceeded the power limits of its hub port. The usual suspects are short circuit on the USB front panel on the computer case and damaged controller on board.
MotherboardTPM-CLR-PROMPT
After turning on the PC (often when changing the CPU), a message will appear asking you to press Y or N regarding fTPM NV recovery. Common triggers are replacing the processor with a new model, the BIOS update…
MotherboardVRM-OVERTEMP-THROT
Processors with a high TDP (i9, Ryzen 9) reduce performance due to overheating of the power supply circuits (VRM) of the board. The usual suspects are an entry-level motherboard with insufficient VRMs for a powerful…
MotherboardPCIE-GEN-MISMATCH
GPU or NVMe SSD running on PCIe 3.0 instead of PCIe 4.0/5.0, performance is significantly reduced. Reports of PCIe generation - speed mismatch usually describe a sudden crash, brief unresponsiveness, or a stop-code…
MotherboardUSB-OVERCURRENT
System shutting down after 15 seconds to protect motherboard from USB short circuit. Another common trigger is damaged USB device.
MotherboardUSB-CONTROLLER-ERROR
The motherboard's USB controller reports a Code 43 (device stopped) or Code 10 (cannot start) error in Device Manager. This affects all USB ports managed by the failing controller.
MotherboardAUDIO-CONTROLLER-NO-SOUND
The onboard audio controller reports Code 10 (This device cannot start) in Device Manager, resulting in complete loss of audio. This is extremely common after Windows updates that replace audio drivers, or when the…
MotherboardTHUNDERBOLT-CONTROLLER-ERROR
The Thunderbolt controller (Intel JHL series or AMD equivalent) fails to initialize properly. Thunderbolt ports show up as non-functional in Device Manager or are completely absent.
MotherboardPOST-CODE-99
Motherboard debug code 99 indicates a failure during Super I/O chip initialization, which handles legacy hardware connections, front panel ports, and display outputs. Most commonly caused by loose display cables,…
MotherboardPOST-CODE-A2
Motherboard debug code A2 indicates that the BIOS is attempting to detect and initialize SATA/IDE storage drives but has failed or encountered a timeout. Most commonly caused by bad SSD/HDD data cables, dead drive…
