I just bought a new cpu fan. It's an Igloo 2470 light for Athlon xp 3000+ 19 dba. I was told that it would work without a problem. My mobo is Jetway v266b and AMD athlon xp 2000 processor socket a. After I put the new fan in the comp won't start... I get an error message : cpufan does not function properly. I do not understand it and have not found any solution... please help
