Help I need somebody ;)

Hi guys.
I have HP notebook I've installed windows 7 actually not me but after 3 months it became very slow so I decided to install windows vista not the specialized one I meant the normal vista but it required drivers so I installed modified edition for windows 7 called " Last OS" I didn't notice that "Last OS is just for 64 bit It didn't work so can u tell me what I gotta do install normal windows 7 for 3 bit or I have to get specialized windows for notebooks.
Regards.

You may like to get a DVD & license key from a good source like:
Windows Download and Shop - Microsoft Windows

This is not the way to proceed. Vista will never run as good as getting a perfect Clean Reinstall - Factory OEM Windows 7 following the steps given to install your licensed version with the installer provided.

It also sounds like you're getting into some dodgy versions of Vista there, so I would stay away from anything illegal since you bought a Win7 license with the laptop which lasts as long as the PC does to reinstall however you want. The blue link above will show you how to get and keep a perfect install.
