Once I turn on my cpu I get to the XP pro loading screen next i get the black screen. It will stay that way until I restart. I have check my Maxtor hdd for errors and I found none. I also did a memtest and found no errors as well. I am using an onboard video card..I think i need to add a new AGP video card as its replacement. Before I do that.. does anyone have any other solutions to my problem?
