BSOD Zotac 460 Gtx AMP in Windows 7..

I just bought an used Zotac Geforce 460 gtx AMP, which was about 8 months old.
I replaced my older geforce 8800 GTX, which had been running for ages with no
problems..

But after installing the Zotac, I get a BSOD when I boot windows 7, in
a file called nvlddmkm.sys.
I tried reinstalling windows 7, just to be sure, no old gfx driver was
interfering, but same result here.

Then I tried windows XP, and here I got to the login screen, but with
alot of artifacts on the screen, looking like a memory dump...
Shortly after this a BSOD and error nvdisp.

Anyone got a clue ??
Is the card defect, the seller said it worked perfect ?!

Artefacts are usually caused by bad cards (normally defective Video RAM or bad cooling). Maybe you can make sure the fan on the card works, provided it isn't passively cooled.

Yup,  that could be it..
But it crashes after being turned on in like 30 seconds of dos (no game)..
So doubt, its a heat problem..

what power supply do you have?  that card can consume about 170 W  http://www.techpowerup.com/reviews/Zotac/GeForce_GTX_460_Amp_Edition/29.html

calculate if your pS can handle the load - and leave a fair margin : http://www.antec.outervision.com/

btw - you did connect the 2 power connectors to the board?

What does it mean to be "Always On"?

According to the calculator I need 319 W.. So 650 W should be sufficient..

that seems very low -  did you put in cpu, disks; cd drives etc, and ram also?

no fans, or usb devices?  but i agree -that is sufficient, even for somemore devices - seems very low to me...a bit astonished

Nope thats it, cpu only take 75w, so cpufan hardly turns... :-)

But i'm closing the conclusion, that the gfx card i defect...

Just inserted my old msi 8800 gtx and everything worked again..
And my old card uses more power  ;-)..

Now I just have make a RMA to Zotac, which has almost non existing support...

that is less promising...but glad you solved the problem
you can always test if it works if you boot from a live Knoppix cd - other OS and drivers :
