need help testing this Nvidia geforce GTX 675 with a multimeter.

I don't think you'll be doing too much testing on that with a multimeter.
The device looks to be bus powered. You caln look up the specs of the bus to determine where the power connections are, but I'd be surprised if that's the cause.
And what is the fault? (and if you have any other information like "it happened just after I dropped my laptop", provide that too)
That board has a heap of BGA devices. Testing them often requires x-raying the board!

it happened after switching UEFI to legacy boot and switch back or vice versa. I've tried installing the drivers and it says that i need to install an Intel driver. I've tried every driver possiblee and it's just not seeming to recognize the GPU. I tried reinstalling Windows 7 and no luck... It recognizes the integrated graphics card but not in the NVIDIA. it just says is a problem when trying to download the driver for it . and on the nvidia website it can't detect a GPU. . . in the manage devices it shows the VGA adapter but no video GPU or HDMI inut of any kind just the VGA. when I go to try to uninstall the VGA adapter it says it needs to reboot. it boots back up and starts back up showing the same thing. also I've tried booting from both boot modes and both of them get the same results
That's weird.
It either is, or isn't connected with your change from UEFI to Legacy boot mode.
If it is, then the problem is likely to be a configuration issue, either in the card, and/or on the motherboard. can you reset both of them completely?
If it isn't, then it may be a hardware failure. I would try another card first. If that works, you know there's something up with the card. If it doesn't work, then suspect the motherboard. At this point you could try probing the supply pins on the interface, or even the 12V rails on the power supply (and indeed *all* the rails on the power supply)
Be careful probing because the pitch of the pins on the interface is small and shorting pins could easily toast your motherboard.
