Hard drive and gfx card failing at the same time
So i was playing a game today and my computer crashed while loading into a map, after rebooting the boot image was distorted and it failed to boot into windows 8. bios functioned but there was graphical errors, i replaced my gfx card with my integrated graphics and the graphical errors were gone, but windows still failed to boot. i tried booting into windows 7 on my old hard drive and it worked fine, i could browse files on my new hardrive as well and videos seem uncorrupted. is it possible that gfx card failure could corrupt a windows installation, or that a broken harddrive could corrupt a gfx card? is my only option to wipe my harddrive? and can the bios on my graphics card be restored if that is the problem with it?
