Hi everyone, I really need help with a problem I'm having, cos I'm getting nowhere and am at my wit's end. Recently I upgraded my CPU, Motherboard, RAM, Soundcard & Monitor. Ever since doing so I have had problems with my graphics card. It's a XFX 256MB GeForce 6800 GT (AGP) and worked perfectly on my old system for almost a year. When I installed it into my new machine the display corrupts. I returned it to the manufacturers who tested it and their diagnosis was: "PASSED - visual check. post. load windows and drivers. FAILED - visual colour/display check(when put to more than 640 and 16 bit the card has corruption and crashes)" They replaced the card, but after installing the new card into my machine exactly the same problem occurs. I've tested the card in another machine after putting it in mine and it corrupts on that too (as did the old one). My new machine is currently running fine with a PNY GeForce FX 5500. I've tested the voltages on my PSU (Enermax 480W) and they appear to be fine, but I replaced it anyway for an Artic 600W PSU just in case. I think it's unlikely that they will have sent out a damaged replacement graphics card that suffers from exactly the same problem as the orginal. My only thought is that my PC is frying them. I'm going to speak to the manufacturers again tomorrow to see if I can get another replacement, but I obviously don't want to destroy another if it is replaced. Does anyone have any ideas as to how I can test my PC to see if it is frying the cards? Or any other advice that may help? Sorry for such a huge post and thanks for reading it. PC Spec...

If you running the FX 5500 on the new machine Then it has to be a lot of bad cards they have in stock.? I would send it back and if they send you another one, test it on your old PC first. If it works then try it on the new PC. That is the only way I would test it. <===Lefty===

I'm hoping they have a lot of bad cards, but seems like too much of a coincidence. Plus the card was working fine in my old system. It is working fine with the FX 5500, but there is one difference with the cards - the 6800GT has to be plugged directly into the PSU, whereas the FX 5500 doesn't, so not really an accurate comparison, hence me replacing the PSU. Could a dodgy PSU fry a graphics card?

This not my area of expertise and I doubt if it's the problem. But I wonder if it could be a compatibility thing. I know different levels of AGP cards use different voltages. AGP info

Both the graphics card and motherboard have AGP 3.0, so should be compatible. I've checked the AGP voltage setting in the BIOS and it is set at 1.5V. So should be ok from a voltage/compatibility point of view, but I may be wrong! Thanks

Hey, this has just happened to me. I'm yet to test it in another system, but my card is the same make and model, dont know what is going on, its a year old as well. Only moderate overclocking with the software supplied. Thanks, Alex
