So i just got finished installing everything into my new computer. I put in my Windows XP and it runs like it should. It gets to the screen where I need to hit enter to continue. I forgot to plug in keyboard beforehand, and it didn't read teh keyboard when i then plugged it in. I reset the computer with the keyboard plugged in. Now it reads the keyboard and it motherboard screen pops, but instead of going to the XP installer It is a black screen with a "_" blinking in the top left hand of the screen. Please Help!
