I ran my computer through a test on this site. They say thay have a bios upgrade available for my motherboard. Is there any reason to do a bios upgrade? Will there be any performance gain. Its a sis 648 motherboard and a p4 2.4 computer. tia http://www.esupport.com/biosagent/index.cfm
Only do a BIOS upgrade if your system is not running properly, or you are adding hardware that needs improved BIOS "tweaks".
By the way, if you screw-up your BIOS upgrade or you happen to have a power failure while you are in the middle of flashing a new BIOS into your motherboard, you are in a VERY HIGH RISK area of doing irreversible harm to your motherboard. Like Nitro said, if it isn't broke, don't mess with it!
