So today I opened a file I shouldnt have from a 10 year old abandonware game I found on a site. My pc reset and didnt boot up. Fair enough, many steps later I managed to get windows on to a spare hd I had lying around and use that to "fix" my boot disc. Problem now is, if I start up my pc using the standard C drive, it hangs and still doesnt work. But if I start it pointing to the G drive (the one with the windows disc on) then it lets me chose windows and boots fine off my boot disc. So seriously what on earth have I done lol.
