Sorry for the late response vandiesel, just got back from work. I am using Windows 7 RC 64-bit edition. I was also using the BIOS dated 1/13/09 (lol I wanted to see if the latest BIOS 6/3/09 was better; however my RAM doesn't like the default voltage and now my system refuses to post). Good luck and hopefully we can figure out your issue.
