Windows 7: Why my laptop works fine using ubuntu live cd but not with windows 7?

When using the installed windows 7 my laptop keeps crashing no matter what web browser I'm using, what antivirus I use etc. The 'not responding' thing always bugging me plus occasional BSoD and regular freezes. I tried clean installing using windows CD but that didn't solve my issue.

Posted this question on several forums already.. hoping someone could solve this.

First Evenstevens, Ubuntu will run on a packing box with memory

I would not compare windows 7 with a bootable cdrom with Ubuntu.

What you need to do is to properly fill out your system specifications so that everyone here who helps will have some idea of what your configuration is. then running some diagnostics so that it can be determined what exactly is going wrong with your windows 7 installation.
