can't upgrade bios anymore on my Gigabyte Z170 gaming 3 motherboard

Solution
Have you used it before? Wasn't aware BIOS updates could be read from a SD card. Or even boot from a SD Card, regardless if it is in a USB reader.


No problem, if that doesn't work. Make sure the files are not corrupted by downloading them straight from Gigabyte themselves. I have the Gaming 3, but due to moving, it is in storage. Is there a reason why you are updating?
