Can you provide me with a link to some information about applying SP1. And do you think that reinstalling the power management and ACPI Fixed Features button can help me with my problem. I've also updated the display driver and BIOS. what kind of video card are you running? won't need Sp1 to run war 3. what is the configuration of your computer? (ram, cpu speed, HD, video card, etc) have you update war 3 all the way? HP Pavilion dv9207us 2GB intel core duo 2 x 1.75ghz 160HD, Geforce Go 7600 and yeah, my war3 is up to date because I play on battlenet
