Sounds like you're using a bunch of XPired methods for trying to install Win7 including using the Black Viper which is absolutely unneeded for an OS as lean as Win7 with no unnecessary overhead. Win7 solved that issue and became the Black Viper by setting all Services not absolutely needed at Startup to Manual on Fast Triggers. It is a perfect OS not needing any tweaking when there's a perfect install on adequate hardware.
So I would let go of the old methods not needed in the first feather light OS, follow only the steps and use only the tools and methods in Clean Reinstall Windows 7, and you will get and keep a perfect install to the exact extent you do.
