Mine was probably not doing my proper research when my replacing my old mother board after it short circuited. I bought a completely different motherboard with a completely different chipset. When I had finally finished reinstalling my board, I fired up windows. It didn't boot. I went through the bios and finagled (for l the lack of a better term) through the system boot priorities. Nothing worked. I ended up accidentally deleting most of my partitions and corrupting the OS as a whole. It cost me all of my data and the vast majority of my pride. I eventually learned what the problem was and installed a new version of windows. I will never make that mistake again.
