My bad, the post should say that I purchased an Asus A55BM-E motherboard with an AMD a10 6800k ap. But that it won't boot up past the Windows logo start up and from there simply freezes and restarts. It's not an issue with the hard drive as I've tested the hard drive on another pc and the os booted fine. So I don't know what could be wrong ? I have 8gb pny 1600 DDR3 ram as well and Windows 7 64 bit.
