Scrolling Vertical Lines, even in BIOS

I just got a EVGA GeForce GTX 950 and it ran fine for day, then suddenly, I started getting vertical lines scrolling right-to-left across the screen. I already swapped out both monitor and cable, which work fine on another computer.

It even shows up on the POST screen and BIOS setup, before the display drivers load. It doesn't seem to be a GPU issue, because it doesn't capture when I record the screen, just a display issue. I've tried re-seating the card, to rule out a dirty connection, but am otherwise stumped.

Anyone have any idea what might be causing this?

Windows 7 Home 64
Intel Core i7-4770
ASUS Z97-A
 
Solution
If the monitors and cables have been replaced already, I can only suspect the GPU being the issue. It might not be the actually processing of the display, but perhaps some parts of the card that is involved with the providing output to the ports on the card.

Just in case, try swapping in a different GPU into that PCI-e slot and see what happens. As well, try putting the GTX950 into another system and see if the same thing occurs. If the alternate GPU works fine with that setup, and the GTX950 has the same issue on another system, we can be certain it's the GTX950 itself that is the issue.

The original issue was with a DVI, only had the one dvi port to try, but problem persists when switching to HDMI.
