I have an HP Pavillion dv9700, and it has an nvidea GeForce 8600M card, 4 gigs of ram, and an Intel Core 2 Duo @ 2.1Ghz. This is a fresh install of windows 7 professional x64, I did a format and everything. If this is not enough information about my setup please let me know, and I will post more information. Before I installed win 7 I was on vista. I started having some trouble with the infamous 'Display Driver Stopped Responding and Has Recovered' problem, and then the nvlddmkm blue screen. So I decided to say whatever and do a fresh windows 7 install. So far windows 7 works great as long as I don't have nvidea drivers installed. I have tried installing the 179.48 win7 x64 beta drivers, and the 257.21 win7 x64bit international whql drivers. The 179.48 caused blue screens when starting up, and the 257.21 just would hang when starting up, and not go anywhere. I am worried that the problem is my physical card, and not the software around it. Do you guys have any ideas as to why I am not able to boot into windows when I have nvidea drivers installed?
