Have a look at the instructions for a repair install here - they'll help avoid most of the pitfalls...

Microsoft Windows 7 Home Premium 64-bit 7600 Multiprocessor Free

Hello Noel
I'm just reporting back that I actually did a clean install instead. Thanks to some easy guides on this forum, I not only was able to do it easily but also I leaned many things with this and other BSOD problems I had.
I got an .iso file with SP1 version. Everything now is smooth and perfect
Thanks again for spending your time helping me out.
