Windows 7: i think my brand new VIDEO CARD is broken

i think my brand new VIDEO CARD is broken

i just bought two 1gb Nvidia 9800 GT yesterday and now i think one of them is broke..

i was rendering (in Revit Architecture) when my monitor turned off.. (it says no signal) but my CPU was still on so I tried turning my monitor on & off to see if it helps, but to no avail.


so I restarted my computer but i still get no signal on my monitor...

so I connected my monitor to my other video card and it worked. I went to device manager but there's only 1 video card detected... is it broken or do i have to just remove it and place it back on the mother board ?
I really need the video card right now for my project since my deadline is due tomorrow

Test one at a time in the slot that has the working card in it and then you will know for sure.

It would seem standard H/W troubleshooting procedures are in order here. You've already taken the first step to be sure that your monitor is still working - you plugged it into the other card.

Continue the process:
  • Move both cards
  • Re-insert the "broken" card
  • Does that work?
  • If not, swap cards. Does that work?
  • If both worked seperately, install both cards and try again.
  • Your results will point to the problem.
  • If the above don't provide definitive answers, installing the "broken" card in a different computer might help narrow down the problem.
  • You might also want to remove the device drivers and re-install the very most recent from the manufacturer.

Defective Motherboard or maybe the PSU has gone South, did you make sure it was going to handle 2 9800GT's, how many Watts is it? Have you got another computer you can test the Video cards on, maybe a friends?

Just had a look on the SLI Zone for a similar topic and people there state

Quote:
2x 9800 GT's would run on a 650w PSU but only if that PSU had a +12v rail that supplied 28 amps min

That seems like it should be enough, how many 12v Rails is that split into?

Is it possible for you to test the cards on your computer your using now, it seems like they aren't the problem but it's good to make sure, also have you been doing any overclocking, have you tried to reset the cmos?
