    Why does my Biostar motherboard say CPU Overheated?
    • N
      Nicole EwingAug 2, 2025
      If the Biostar motherboard indicates CPU overheating, this means the CPU protection has been activated. To resolve this, disconnect the power cord from the power supply for a few seconds, then wait. Plug the power cord back in and start the system. If the issue persists, clear the CMOS data, wait a few seconds, and then power on the system again.

      If your Biostar motherboard system fails to boot from a hard disk but boots from an optical drive, check the cable connecting the disk to the disk controller board. Ensure both ends are securely plugged in and verify the drive type in the standard CMOS setup. Also, remember to back up your hard drive, as hard disks can fail at any time.
