First of all, wow, thanks for the support!; I didn't get this level of support on neowin.net... The fact is that I don't get video at all. From the moment I turn on the computer untill it boots into XP (or LH). Question: is it normal for a computer to boot even without a video card installed/working? I have 2 operating systems: Longhorn build 4047 and Windows XP SP2. And it doesn't work on any of the two.I can't install the drivers since I get no image. I'm using my old Riva TNT2 card now, and I can't install ATI drivers while using this card... (and, also, I can't use the SmartDoctor software because it detects that I'm using an nVidia card. What's a basic bart pe/win disk? I tested the Asus Radeon card on another computer and it does the same thing. I don't... Did that already, still the same thing. It is XT by default. I have OC'd it, but I have returned to normal frequencies in the end. Thanks again for the help.
