Not necessarily. Most often, it’s a thermal environment issue, not a hardware defect.

Locate the 8-pin or 16-pin SPI flash chip on your motherboard. It’s often labeled:

Use a non-contact infrared thermometer to check its temperature. Wait until it reads below 45°C.

Aggressive CPU overclocking raises VRM (voltage regulator module) temperatures. The BIOS chip is often positioned close to VRMs. When VRMs hit 90°C+, the nearby flash chip can exceed 60°C.

During critical flash operations, the system may temporarily disable interrupts — including thermal monitoring. If a cooling fan fails or heatsink is inadequate, temperatures can spike.
