Do you have the installation disc for Win7? if so, you can do the following things to try and restore your system:
Startup Repair
If that doesn't help, then you can try to disable the services in MSconfig and see if you can get into Windows long enough to do this:
Repair Install
Otherwise, if neither of these are working, I think your only other option is to do a custom install. If you do, dont format the drive, you will loose your files.
Custom Install Windows 7
If you do the installation right, your files from your previous installation will be in a Windows.old folder which you can then insert back into your new installation. You will need to re-install all of your programs though: Windows.old folder - Restore into a new installation
