Best Approach for Upgrading Motherboard With OEM Windows?

[Zamaj]

I'm sorry if there is a better section to put this in, but it seemed to be the best option for my question.

I currently have an HP Pavilion p7-1102

Specs:
Windows 7 Home Premium 64-bit SP1
Pegatron 2ACD
AMD A8-3800
1 TB Hitachi SATA
512 MB ATI AMD 6550 (integrated)
8 GB DDR3

I want to do an overhaul, upgrading to the following:
i5 4690k
[compatible Z97 chipset MOBO, preferably with multiple PCIe x16 for future SLI options - still undecided on exact model]
GTX 970
Corsair CX600M

I have an OEM version of Windows, which I understand will not allow me to upgrade my motherboard. I was trying to avoid buying a retail copy of Windows 7, but I've done some extensive research and it looks like I'm going to have to buy it.

My question is: What is the best way to go about installing retail Windows with all the new components while keeping all of the programs and files on my HDD? I wasn't able to find anything all that helpful in my research, and I'm hoping someone can outline the best approach. Thanks!

You can buy an OEM version, which is less $$. However, you will have the same limitations as the OEM supplied HP OS.

I didn't see a new case on your list, but the HP probably won't accept a different motherboard (and the I/O panel). You will also need new memory (you list 8GB DDR3 but what is the memory speed? if you install a new CPU with a fast I/O bus you don't want to slow it down with slow memory). You are actually building a new PC. You can reuse the SATA hard drive and probably the optical drive but that is about the extent of it. Everything else will have to be new. If you plan on possible multiple video cards I would go with a 1000 watt (modular) power supply. No use buying a smaller power supply that may not handle what you ultimately want.

As far as the programs on your hard drive, when you install the new OS you will have to reinstall all programs. You can backup your user data, music, photos, etc to some other media. Do a "clean" install which involves formatting the hard drive then installing Windows, whatever drivers that will be needed and then your application software.

While a Clean Reinstall Windows 7 is always best especially if you stick with the tools and methods compiled within, you can Adjust Win7 to boot on new hardware with Paragon Adaptive Restore CD.

You would then reactivate with the new retail OEM key at Computer>Properties. If that link is missing, use an Elevated Command Prompt to activate with SLMgr Commands and Options.
