This is my mainboard. I changed most part of this PC but mainboard still the same. I just bought a GPU and when I checked GPU-Z info it says "x16 1.1 @ x16 1.1" or something like that. I want to use PCI-E 2.0 and I don't know if this motherboard supports it. So I decided to update my BIOS but I don't know how to do it. I have read some topics here but I have no idea what should I do. Can someone help me to update my bios? Thanks.
