So, I tried to upgrade my graphics card today. I don't know the specs for either card, but I know both have worked in my unit before. When I tried to turn it on, I got the magical black screen of boot options. I tried them all, none of them went through and it just kept on going back to that miserable screen. I switched the cards back, but it still won't go. Everything I've seen so far tells me to use the Windows XP CD... which I don't have...
I'm at a loss as for what to do, please help!
