Hey last night i tried to reinstall xp on my computer. Everything was going well but after it had deleted the previous version of xp the cd popped out for no reason. So i just pushed it in again but then it started saying that it cant install it because there was no previous version of xp on that computer. When i turn it on now it says that its missing components and just tells me to restart it doesn't go to the windows screen at all. WHAT SHOULD I DO???!!?!
