What to do if Biostar TZ77A Motherboard system is inoperative but keyboard lights are on?
If the Biostar Motherboard system is inoperative but the keyboard lights are on, the power indicator lights are lit, and the hard drives are running, press down firmly on both ends of the DIMM with even pressure until the module snaps into place.
How to troubleshoot no power in Biostar TZ77A Motherboard system?
If there is no power in the Biostar Motherboard system, and the power LED does not shine while the fan of the power supply does not work, ensure the power cable is securely plugged in, and replace the cable if necessary. Contact technical support.
What to do if my Biostar TZ77A has no power?
If there's no power in your Biostar Motherboard system, ensure the power cable is securely plugged in. If the problem persists, try replacing the cable. If neither solution works, contact technical support.
Why won't my Biostar Motherboard boot after installing a second hard drive?
If your Biostar Motherboard system fails to boot after installing a second hard drive, ensure the master/slave jumpers are correctly set. Then, run the SETUP program and select the correct drive types. For compatibility issues with other drives, contact the drive manufacturers.
What to do if Biostar TZ77A won't boot from hard drive?
If your Biostar Motherboard system boots from the optical drive but not from the hard disk drive, first check the cable running from the disk to the disk controller board to ensure both ends are securely plugged in. Also, check the drive type in the standard CMOS setup. It's also important to back up your hard drive, as hard disks can fail at any time.
