I am in need of down grading because of driver issues for this equipment that I've purchased and it will not currently run on 64 bit Vista. Can someone give me the simplest step by step way to make this happen? I am not knowledgeable in this area so please keep it as ABC as posssible for me.
I have the HP Pavilion dv4 Notebook PC
AMD Turion X2 Dual-Core Mobile RM-72 2.10 Ghz
64 Bit Operating System
Windows Vista Home PremiumService Pack 1

I discourage anybody except supergeeks from trying to run XP 64 bit, even though I believe that it is one of the best OS'es MS ever put out. Very fast and stable. But if you think you are having driver issues with Vista 64 bit you ain't seen nothing yet!. You do not HAVE to run a 64 bit OS on machines with 64 bit CPUs. 32 bit Vista or Xp will run just fine, with only a slight performance decrease. The biggest issue is the max memory. 32 bit versions can only access roughly 3 gigs where the sky is basically the limit on 64 bit versions. If you MUST run XP 64 bit keep in mind that HP provides zero driver support and you will have to hunt down drivers from 3rd party websites and maybe even hack drivers to make them work. And that is just for the computer. God help you if you have a scanner or even a printer for which the mfr has not written an XP 64 bit driver.
What drivers there are can be found for the most part on planetamd64.com.

This is a guide for XP 32 bit version. I think then after this what Huffer wrote You will want to try this system.
First make Vista backup. Here You've got all informations how to do it.
You have a folder with drivers & programs that may prove very helpful after XP downgrade. Copy folder C:\Swsetup to DVD Before formatting your hdd.
Now You need to slipstream Your Sata drivers win nLite.
Be sure also that You are using WinXP SP2 version. If you haven't got SP2 version here you can download this service pack
and here You have got guide how to slipstream this file with Your system again by nLite.
In this program You can even burn Your new XP cd with this driver.
