I am upgrading my mobo due to my graphics card incompatibility, from a foxxconn that came with my hp pavillion p7-1597c (psu already changed to 500w psu) to a Msi H61M-P31. Will i need to reinstall windows 8? If i do, how do i install without buying a windows 8 disk cause windows 8 was already installed when I bought my computer.
For best results, yes, reinstall Windows. As for how to reinstall, you can probably go to the Microsoft website and using your Windows Product Key (should be on a label attached to the outside of the computer. usually on the side or back) and download Windows as a file that you can burn to disc or use from a USB drive. Instructions should be on the website. Otherwise, call HP and tell them you need a Windows disc and they will likely send you one free of charge.
