hi all. just made the jump from nvidia to ati. im having a problem which makes me think that the card is defective. after uninstalling nvidia driver running driver cleaner and reg cleaner i installed new card and drivers per manual. i had a bear of a time installind ati cat 3.6. at first i would get a black screen at the welcome screen (xp). something about a gart driver for non intel chipsets would cause the black screen. problem is mine is an intel chipset (530). so i go into safe mode to install the drivers. after playing around i finally get the drivers installed correctly. ( never had this problem with nvidia drivers before click click and bam i was up and running). never the less i am getting faint yellow vertical banding top to bottom in 2d apps. also a smal vertical line to the left of my mouse. so i try to run 3d mark 2001 and the graphics were badly corrupted. after several tries i decided to reformat... same problem. what are the chances that you buy a new card and it is defective? dont they do some kind of testing on them before they release it. it could very well be user error. i dont know, as ive never had an ati card before. i kept getting an error about an inf file missing and then it would tell me that my ati driver was causing my system instability. im at my wits end. i have an rma # and am prepared to send it back (allstarshop.com)they were nice and appologized for the problem i was having. i just want to know if anyone has any answers as i dont want to unnecissarily pay for shipping back and forth if it is some thing that i am doing wrong.. sorry this post is so long i just wanted to let everyone know what i have tried so far. her are my system specs....p4 2.4b...512mb pc 1066...480 watts true blue power supply.. sound laster audigy...60 gig hd 160 gig hd..dvd player and cd burner.. tried hooking up the power cable to the card in many different configs.. wore grounding strap while working on it.. whew.. thanks in advance for any help ..oh sorry gigabyte ga- 8hixp mb
