I'm receiving a number of BSODs and some boot and random freezes with a new install of windows 7 ultimate 64 bit. I've tried hdd tests which passed. I even changed the hard drive. So then I did several different ram tests from the ultimate boot cd that came up fine and I even took one stick out and tried it and again with the other stick and then tried them both in the second slot. No luck. Can't seem to figure out what the problem is
