OptiPlex 755 Mini-Tower / Drivers Specific

PJAmerica here. I recently bought a refurbished Dell OptiPlex 755 Mini-Tower on eBay for $110. Before that I bought and owned a Dell Dimension 3000 which is a world of difference in performance and capabilities. The OptiPlex came with Windows 7 Home Premium and I love it but I also have the Vista Business Product Key on my PC as well and installed it with great ease. I didn't stick with it long though and wiped my drive. I wanna reinstall it again as my primary OS and dual boot Windows 7 as the secondary OS. My big concern is having all of the right drivers for it. DSS, Chipset, Video, Audio, etc.. This is important to me as I really wanna get Vista installed properly with the correct drivers starting out of the gate.

Dell is not very specific with me and I really find it a challenge to find the right drivers. Any help would be greatly appreciated. I have heard so many bad things about Vista but I want to install and use it and make up my own mind first. If it works then I will use it until 2017 when support ends.

Ps. I heard that my computer is backward compatible with Windows XP Professional 64-bit as well. Unfortunately I don't have a product key for it. Is there a place where maybe I can find an OEM copy for free that will automatically activate like it did on my Old Dell Dimension 3000 did? Or am I out of luck?

 

Windows 7 and Windows Vista are practically the exact same thing so I don't know why you'd want to dual-boot with it.
(Except 7 is now forcing you to upgrade to Windows 10, and doesn't have its own mail client or movie maker built in)

I use x64 Vista and it performs really well on an AMD processor.

Give me the list of drivers you need and I'll create a .zip archive with all of them for you. Put it on a USB stick first so you can use them.

Vista is very good at finding drivers itself too, though.

I don't know about compatibility though, but they probably won't be compatible with each other, if you already have a legal key with each OS then use them, I can't say anything else on a forum...

 

Vista is the direct predecessor indeed but debating they are the same is semantics. I have use for Windows 7 and I like it. But I want to install the native OS which is Vista on it.

I need DSS, Chipset, Network, Audio, Video, etc. as described.

 

Resolved. Thanks for the replies.

 

Good

I was going to make a zip file but I didn't have much time to do stuff in, and it would have been huge.

Any more questions ask here or at another community (I'm the only user who posts here now).
