(Copied verbatim from the MS Technet forum. They don't seem to be quite as on the ball as you all are.) At first, things seemed great. When it first boots into the OS after installation, Windows 7 runs beautifully. No hiccups, no issues, no complaints. Other than it missing a couple of drivers, everything seems to be working beautifully. Then I reboot. Things get nasty after that. When going into 7 for the second time after an install, it takes forever to boot, and when it does, it takes forever to open a window. Jumping from one window to another hangs the OS for about a minute before it'll do anything. It isn't thrashing the harddrive, and going to the performance tab in task manager doesn't show anything weird going on at all. In fact, according to it, things look pretty good. Keep in mind that when I reboot, I'm not making any changes whatsoever. 7 just decides to freak out for reasons unknown. I've already tried to reinstall the OS, and it ended up doing the exact same thing. That makes me think it might be some hardware issue, but if that were the case, why would it work perfectly the first time it boots? Any ideas? My specs are: AMD Opteron 185 dual core, socket 939 Asrock DualSata2 motherboard 2Gb DDR400 G-skill Asus Geforce 8800GTS512 Western Digital 80Gb SATA 3.0 HDD Not exactly a powerhouse, but still a fairly decent machine. I could really use the help here. As things are, Win7 isn't good for anything except looking pretty on my monitor. If I can't get this resolved by tomorrow, I'm gonna have to roll back to XP and wait for the next beta rev to arrive, and I don't wanna have to do that unless I absolutely have to. So...any help would be greatly appreciated.
