I've recently upgraded my computer, replacing both the motherboard and the CPU. I was using an ABIT AW8 motherboard and an Intel Pentium 4 3.2 ghz processor. Now I've got an ASUS P5N-D motherboard and an Intel Core 2 Quad Q8400 CPU, and now none of my 5 fans will speed up! Since none of them are working right, I'm assuming it's a software problem. Does anyone have any suggestions to fix it? Thanks!
