I have a windows 7 machine that lost the hard drive. I put a new hard drive in and reloaded windows 7 and it now goes through start up, says loading windows and then immediately says logging off and shutting down and turns off. This happens in both normal and safe mode but if I use last known good configuration it boots fine until I reboot it. It's an Asus mobo and a 1TB WD HD. Any help would be greatly appreciated! Thanks!
