Hey recently my explorer.exe messed up and wouldn't open, and now whenever I try to reinstall Windows 7, it says that all the sources for installation aren't available. I've tried formatting my hard drive but that didn't do anything. Any1 got any ideas as to how I can fix this to make Windows install again? Whenever I boot from my Windows 7 DVD and Windows XP cd they both blue screen of death in the middle of installation. I formatted my hard drive through my Windows XP cd.
