I using an GA-8PENXP motherboard with a P4 3.0 ghz w/ 2 gig ram with Win XP pro with SP2. Also using the latest version from gigabyte site of Easytune4. My problem: Everytime I start my computer, Easytune4 loads but cpu fan doesn't slow down. But: If I re-install Easytune4, when it reboots at the end of installation, Easytune4 works and cpu fan slows down. If I reboot tho, Easytune4 won't slow down cpu fan, unless I re-install it again. Any suggestions? Thanks, Bob
