Thanks alot for your reply.
I have been searching for the Bios Update. it has Acer motherboard. Originally, it has sandy Bridge I5 2300 processor. The only digits i can find in the motherboard is this MBGBL01002111081C2430B1...But i'm sure it has AMI bios..still can't find the Bios..
Try running CPU-Z. It will identify the BIOS name and version for you. But You'll still have to locate an update online. Check the Gateway site for the BIOS.
