Hello, I am thinking of upgrading my old AMD 965 to a newer Intel i5 3570K or i5 4670K setup. Obviously, this will require a new motherboard and RAM in addition to the CPU. However, I would like to keep my current Windows 7 Pro 64bit install. I have a lot of programs and games with mods set up in particular ways that are hard (if not impossible in some instances) to reconfigure in the same way. And my Windows 7 install is in good shape (69 from power on to Firefox) so I don't feel a need to wipe my HDD. I am wondering if I can change my motherboard without having to reinstall Windows 7 Pro 64bit and what the process is. First, my current specs: ASUS M3N78 Pro: M3N78 PRO - http://www.asus.com/Motherboards/M3N78_PRO/#overview Windows 7 Pro 64bit with latest updates AMD 965 8GB GDDR2 GTX670 WD Black 2TB (boot drive) Seagate 750GB (backup data drive, unplugged most of the time) ASUS DVD burner Antec Earthwatts 650 Green What I am looking at upgrading to: MSI Z77MA-G45: http://www.msi.com/product/mb/Z77MA-G45.html#/?div=Basic With an i5 3570K and DDR3 RAM of whatever quality brand is on sale. Or MSI Z87-G43: http://us.msi.com/product/mb/Z87-G43.html With an i5 4670K and DDR3 RAM of whatever quality brand is on sale. This is a big change, going from AMD to Intel and ASUS to MSI. So can this hardware change be done without reinstalling Windows 7 Pro 64bit? If so, can someone detail the steps must I take? Note: I do have a data HDD which I use for data backups, so I do have a backup of all my files. I also realize a motherboard switch requires Windows 7 to be reactivated. Thanks for your help.
