Ok, here is my delima. I have an old Gateway computer with Win XP installed on it. When i boot the computer up it runs through everything as normal. right after the "windows XP" boot screen comes up the light on the moniter turns red (from green) and nothing shows up anymore. it seems like the rest of the computer is still doing its normal thing. but nothing shows up on the monitor. i would think it to be the monitor but, it shows everything normal until the boot screen.
