emoate 0 Posted October 22, 2009 Hi! I have a biostar n750a with a 955 be am3 running xp home sp3 and the proper cpu driver installed per amd website. Power now and smart fan turned on in bios but don't work! It did work but I turned it off to do some benchmarking and it has not worked sense any help would be good. I formated HD did clean install no help! I have vista 64 bit on another drive with sp1. I did not see a 64 bit driver on amd web page for vista I'm going to check cpuid for vista 64 cpuz. so I can see if it works on vista. Share this post Link to post
