The computer restarted unexpectedly or encountered and unexpected error

Last night after all the troubles with getting W7 Pro 64bit installed, I finally managed to do it using a USB.

This morning I start installing all my programs and I noticed that my "Windows Experience" number was 1.0. I assumed this was down to it not recognising my graphics card (Geforce 9600M GS).

I downloaded the drivers from Nvidia and installed them. Upon restarting, I received an unexpected error message giving me the option to repair the problem or run windows normally. The latter just caused the machine to restart everytime it was chosen, and the former took the system restore window.

Upon doing this it managed to get me back to the desktop and everything seemed fine. I tried installing the drivers again and it led to the same problem.

By this point I decided to try and reinstall windows from my USB stick. I performed the first section of this, it started on its own as its supposed to, and began trying to complete the installation. At the point where it said "Setup is starting services", a warning appeared saying:

"The computer restarted unexpectedly or encountered and unexpected error. Installation cannto proceed. To install Windows click OK to restart the computer and the installation."

Sure enough, clicking OK leads me to exactly the same message.

After getting sick of this I tried installing W7 for a third time and exactly the same thing happened. Now I am stuck with the choice of 3 Windows 7's on boot, all three leading to the same error.

I am completely lost, can anyone help?

Welcome to the forums :ciao:

Is it a clean install that you are doing? If so, I would use the partition manager in the install phase to totally remove your existing Windows 7 partitions and then create a new clean one and begin the install process again. If you have 3 copies of W7 on your boot menu then things are getting a bit cluttered ;)

Your Windows Experience score of 1 was probably just because the test had not been run yet... although installing the NVIDIA drivers shouldn't cause a problem like that.
