          SPI Chip is probably Winbond W25Q128JV ?

          Computrace (DeviceFreeze) prevents booting.
          Would try to clean it myself but this is my first time trying this and I have no idea about the DMI address offsets or whatnot on this chip.. 😔

          Thank you in advance!

                    The actual number on the chip is 25B127DSIG but the CH341 mini software detect it as GD25Q127C

                        It has an admin password on the bios that is the issue

                          if you are not able to select manually or find that chip in software chip list than no issue if your programmer auto detect it as a GD25Q127C just select it and read bios send here some one will fix it your issue
