Has anyone any immediate thoughts on the following problem? I have been looking at a Dell pc that had a 9800 card fitted but was showing very distorted graphics - dominant vertical striping. I took it out and replaced it with a pci card that worked fine. I have since tried the 9800 in another machine which gives similar problems. I received a 9600XT card today and fitted it to the Dell and everything seemed to be working Ok, drivers loaded and booting into windowsXP. After a while the screen went blank and monitor was not receiving a signal from the card, I rebooted the machine a couple of times and the same thing happened. I took the card out a couple of times and reseated it in the agp slot but to no avail. Has anyone quick thoughts as to what may be going on? I intend to try the 9600 card in another machine just to confirm that it does work OK.
