how to update gigabyte m/b bios? i dont know my m/b info

Solution
Sounds like your cmos battery might be dead, try replacing it. But to get your motherboard info download CPUZ:

load it up, then go to the 'mainboard' tab and it will tell you what you have :)

then google that and go to the website, the support page, downloads, and find the newest bios (if you still have the problem after the battery swap)
