http://windows7forums.com/windows-7-support/5894-driver-power-state-failure-bsod-now-hangs-startup.html Since there's no way to bump a topic with new information, and I can't edit the topic title, the only way I can relay this additional information is to make a new topic. Sorry for the additional clutter, but I really really really really REALLY need this working in the next half hour or so! >.< Please? Anyone? I'm offering up $10 for someone to help me out here... "edit"... Well, since nobody was even remotely interested in helping, I figured out a "solution" on my own... I took out a stick of RAM and now run with 1gb, and it works once again. Definitely a bug in the memory management of Win7 RC x64. The RAM was fine and it consistently hung on startup, that's pretty much a definite memory manager bug. Hopefully it'll be fixed, otherwise that's gonna be a huge deal breaker for Win7!
