Perfect Display. No Video

[syedasif]

Hey everyone. I've got this ancient ... no ... medieval Compaq Deskpro. I just upgraded it from Windows 2000 to Windows XP. I don't have any of its drivers but everything's working fine. Display, Audio, Broadband, USB, Everything. The only problem is I can't see no video on it. No avi, no mpeg, no video CDs, no DVDs, No DIVx or XVID or any other codec, just nothing. Now I have The Prestige, The Lord of the Rings and Hollywoodland right here waiting to be played and I can't do nothin about it. So help me PLEAAAAASEEEE!!!! THANKS.
