Need help with 6800GT

I have a problem with a 6800GT I bought used a while back. I never really did more than look at this card for months (purchased it as a back up card) until I got bored today and decided to make sure this thing works.

So here is what happened:

Remove working ATI card and install nVidia card
Turn on system
System runs for 3-5 seconds then turns it self off (LED comes on on video card but fan doesn't).

Anyone have any similiar experiences with a PCI-E card? If anyone has any helpful info, please share.
 
Without jumping to dire claims of defective hardware, the first task I accomplished when testing a new video card is to remove all driver remnants with Driver Cleaner.

Did you have molex power connector plugged into the 6800GT?
 
I did have the power connector plugged in to the card (I was sure to triple check that one). And as far as drivers....it doesn't get far enough into the boot process for the drivers to be a problem.
 
Instead of swapping the cards first, you should have left the ATi card in and then uninstalled its drivers using Driver Cleaner. Then swap cards.
 
I know what you mean....but maybe I wasn't so clear in my first post....

When I turn on my comp, I don't get a display and the computer shuts itself off after only a few seconds, so I really, really, really doubt drivers have anything to do with this problem.
 
I did put the ATI back in and everything works just as it was before. I'm guessing the nvidia is just no good.
 
Not sure on the exact model, but it's an enermax 550w PSU. That's what I thought as well, but it powers my X1800XT fine, so I'm lost.
 
I would probably suggest that you install the new NVidia drivers then remove the ATI drivers - turn off PC change cards then boot up again.

Strange problem though...
 
Anyone have any suggestions besides drivers? Like I've mentioned before, drivers are NOT the problem, the system will NOT boot with the card - it only turns on for a few seconds, shows NO display, and turn back off.
 
Why don't you just try the driver removal to rule it out? The drivers let the computer communicate with your card, and maybe there is a conflict during the boot.
 
I do understand that, however, windows drivers are not helping hardware and software communicate during POST.
 
If you are able to, try both outputs on the card. My friend had one where the DVI wouldn't work. Also try bumping up the AGP voltage in the BIOS while the ATI card is in there. I also agree with you about the drivers, don't know what else you could try. GL
 
ok.. im not gunna suggest drivers... but can you get into bios?.. if you can does it stay in bios? or turn off? cause if it stays on fine.. then its not the card... but you said the fan isnt on?... thoes cards get hot fast... do you have a temperature sensor anywhere where you can check it?.. it might be overheating...

You ask for help...almost all of us suggest driver re installation...and you refuse to even try?

I'm not refusing to try, I'm simply stating that the computer doesn't even get far enough into the boot process to display anything. If it turned itself off while loading windows, or anytime after POST, I would agree with what everyone is saying on drivers, however that is not the case.

I too suspect that maybe the fan not turning on is causing it to overheat, but would a video card overheating cause the entire system to shut down? And do you think it would get hot enough in just a few seconds time?

Why not just try? Just to make sure.

CPUs burn up in a matter of sec but I'm not sure about video cards...
 
Before I go through that trouble, I would like to add my new findings.

The fan itself is working, however, when plugged into the card, the fan doesn't turn on (it will with the fan being powered from elsewhere in the system). So, I'm at the point where I'm ready to toss the card out.

Send it to me. I'll take it off your hands.

I think he's already sure enough that your driver suggestion will not help since at the stage the computer is crashing it has no idea that there is *even such thing as a driver*. Just because someone asks for help doesn't mean they've agreed to try completely irrelevant crud suggested by anybody.
 
That was about a week ago...before I saw his most recent post...now I'd say its dead..

Give me $10-$15 to cover shipping and to leave me with a few extra bucks and it's yours.

Well I would love to but it seems as though my Paypal account has been limited. Seems someone else has tried to access my account therefore causing them to limit me on what I can do.:mad: It should be resolved in a week or so. If you still have it then I will take it....
 
been following this thread...I'll paypal you the $15 bucks asap and see if it works. give me a pm to send the money to.
 
I would clear the CMOS. If you could get into bios (hopefully) reset everything to default. If that didn't work.. I'd try the graphics card outside of the case.
 
I had almost the exact same problem. Got two 6800 GTs. I wanted to give one away to a friend so I checked the 2nd 6800 GT to check if it works properly so I swap cards and PC shuts down after 10-15 seconds. It happened every time so I tried going quickly to the BIOS and found my CPU temperatures were hitting 80C which was the reason my PC would shut itself off. So I would suggest you read CPU temps from your BIOS or just simply add thermal paste and see.

The CPU I had was AMD 3800+ X2
