My motherboard is generating a code 75 on my POST LED, what does this mean?

Last Update: 2010/08/02

The code 75 generally points to hard drive connection, or other IDE device. Almost always this can be easily corrected by making sure all the connections are securely in place. If using IDE make sure the ribbons are not in backwards. If the issue persists try using different ports or different SATA or IDE devices. Sometimes a hard CMOS reset is necessary via the CMOS battery. To do a rest via battery, disconnect the power from the power supply, then disconnect the 8 pin and 24 pin power connectors. Wants power is completely removed from the board, remove the watch like battery and wait for 10 minutes. After 10 minutes has passed, reinsert the battery, reconnect the 8 and 24 pin power connectors, and reconnect your power supply. If using an aftermarket heatsink and the 75 code still occurs, try loosening the screws as this can flex the the board causing the CPU pins to not make good contact. Should the issue still persist you may have a defective CPU or bent CPU pins as the SATA/PATA controller is in the processor. Check for bent CPU pins, if all of the pins are in a uniform, try testing the processor if possible in another system, or using a different processor on the current system. After having completed all trouble shooting methods, the issue still persists, contact EVGA to RMA the board.
