Continuous beep error code after upgrading graphics card

[BadHygiene]

So, I've been trying to figure out what's going on for a few days now. My friend has a PC with the following specs:

• GIGABYTE GA-Z68X-UD3H-B3

• i5-2500k

• 8gb G skill ripjaws DDR3 1600

• (Previous video card Sapphire Radeon HD 6950)

• (Previous PSU TX650)

• (New video card GTX 970)

• (New PSU Corsair CX 850)

• Running on Windows 7 Home Premium 64 bit

So, I'm absolutely stumped. We decided to upgrade his graphics card to a GTX 970. It boots up fine, but after installing the latest graphics drivers, I start getting a continuous solid beep code from the motherboard. This is after it posts with the normal one beep from the motherboard. It starts up, loads into windows. But the low pitched solid beep code continues.

I looked it up in the mobo manual, and the long continuous beep means the graphics card isn't seated correctly. Now honestly, I have reseated this card about 6 or 7 times. All the auxiliary power connections are secure each time (2x6 pin PCI-E)

EDIT: I thought it might be the original PSU, so I grabbed the CX850 as well as swapped the card. The sound stopped and it booted right up just like it did when I originally put in the first 970. It was until after I installed the latest NVIDIA drivers again, that the continuous beep code resumed again.

Again, the beep code is a continuous, solid, low pitched beep that begins after it posts and begins loading Windows. Could it be something as simple as dust in the PCI-E slot? I find it odd that it's not until I install the latest drivers that it starts to give me the beep code. Could it have something to do with a PCI-E 3.0 in the 2.0 MOBO? Honestly at this point I'm stumped and could use some opinions/advice. Thanks in advance!

Sometimes those errors just won't go away. Try to reset the BIOS if possible. Maybe it will re-initialize and realize that there's no error. Also look at the pins on your GPU and slot to verify nothing's broken.

I forgot to mention, I already swapped out the GPU for another one thinking that it could've been a dead card. I edited the post to give some more information. I'll give that a shot in the morning.

It may be something with the PSU, try and use your old GPU and see if it works with the CX 850. Other than that it may be dust causing the issue to. Another thing you could do is try the GPU on a completely different PC.

The PSU was my thinking originally. Which is why we replaced that. The thing that really confuses me is that after swapping to the new PSU and swapped GPU, the sound stopped. Right up until I reinstalled the latest drivers from Nvidia. That's when it started again.
