I brought a K7S5A Pro home, trying to put together a new computer, and right off the bat I noticed the motherboard's CPU fan socket doesn't work, even though the case fan socket works. I tried to ignore it, but two minutes after I tried installing Windows, the computer shuts down for no reason! It won't reboot properly either. I tried clearing the CMOS a few times, nothing, it won't post. I think it's not the other components since I've since tested them on another computer. I think I might have gotten a lemon...
