I cannot get a picture from the card upon initial installation.Prior to installation I removed all ATI software and ran driver cleaner pro. I made sure that the card was seated in the PCI-E slot and that the PCI-E power cable was connected.When I connect the DVI cable my monitor goes into power saving mode and won't come out of it.I re-installed my x800 and everthing is fine.I have ran a XFX 7800 gt OC in this computer and it ran fine. Any suggestions? :
If your PS can't handle the added drain, it will fail to boot. Happened to me when I installed a 5950 Ultra a few years back and I had the Antec True 380. I upgraded to the Antec True 550, no problems. I have never received a dead video card but I'm sure it can happen. I have noticed some cards will have a thicker flange that keeps the card from inserting in the PCIe/PCI all the way, it gets hung up in the guide slot beside the MB. Double check to see if it is fully inserted in the PCIe slot. Also look to see if one of the wires on the molex connector have pushed out.
As a system builder and I have yet to see a DOA video card. It isn't impossible though, not by far. Static electricity kills a lot of components. What normally come to me as DOA cards usually ends up something odd but easily fixed. It may very well be dead but look for other things first.
