Windows 7: Upgrading HP Pavillion DV6000 From 32 bit Vista Home to Windows 7

Hello everyone,
My first time posting here so have patience. I have searched the forum for some answers to a few questions. Would it be worth it to upgrade my HP Pavillion DV6000 from Windows vista 32 bit to Windows 7 64bit? . The warrantie ran out and the hard drive crashed the pc is five years old but is is great shape. I have looked around and as of now windows vista is more expensive than Windows 7 . What I do not understand is why would HP put a 32 bit OS on a 64 bit system ?. Was it not running correct with 64 bit OS?
This laptop has all kinds of cool devices on it webcam remote for media center light scribe including touch controls by power button I do not want to loose any of those functions. It has Nvidia geforce 7100 mobile graphcs to I just want to make pc better without loosing anything.
Anyone know where I can get step by step install for this laptop model I think what I want involves all the drivers including webcam,lightscribe,touch controls which are part of media controls ,remote control for media center?.

System specs

It was likely running just fine with a 32 bit OS. How much memory does it have installed? Better yet, what are the core system specs?

You don't really need a list of instructions. You back up your data, and boot from the Windows 7 disc. I would download drivers for either of your network connections, and see what Windows 7 finds on it's own once installed and once Windows Update runs. You can go back to HP's website for anything it doesn't find. All of those apps should be listed on HP's website, but if not, backup your C:\swsetup directory, too. On all HP's I've dealt with, that folder contains the installers your programs that were preinstalled.

Please download the Windows 7 Upgrade Advisor, which will check your system to see whether you can run Windows 7 on it.

Please also bear in mind that you cannot upgrade from a 32-bit operating system to a 64-bit operating system. It has to be a clean install.

I am installing new sorry if I said other wise. I can not access my computer dead hard drive.

In that case, you need to replace the hard drive before you do anything else.

If everything worked using Windows Vista there's a good chance you'll be OK with Windows 7.

Replace the hard drive, reinstall Vista, run the upgrade software, and then install Windows 7.

Ok that was going to be next question are sata 3 hard drive backwards compadable the hard drive on laptop is Sata 1 will my laptops BIO's see it ?

They are backwards compatible, but you won't get the benefit of the extra speed.

Yea I kinda figured but really can not find many sata 1 drives and the sata 3 is cheap enough thanks folks next time we talk Ill be on my upgraded laptop . (I hope)

OK, hope it goes well for you.
