GTX 760 MARS Issue -Blinking Yellow Lights / Distorted Display

Level 7

Almost a month ago I built my gaming PC so I could be able to play Dragon Age Inquisition. The specs are as follows:

Motherboard: Maximus VII Hero
CPU: i7 4790k
Memory: 16GB RAM
GPU: ASUS GTX 760 Mars
HDD: Seagate 3TB
PSU: Seasonic X-Series 750w

Operating System: Windows 7 Ultimate 64-bit (Activated)

It worked really great after the first week. But after some time, the display/graphics started getting wierd. When I played Dragon Age Inquisition around the 2nd to 3rd week, I noticed that I could see some blinking yellowish lights in the background - It was kind of faint at the time and only happened at some areas of the game. I tried googling and searching this forum but can't find any that describes my issue. 2 days ago, the problem got really bad. The blinking lights increased and became more persistent, covering the entire display in each area of the game. I also encountered problems when in the desktop or browsing where the display becomes suddenly distorted with veritcal lines of white or black (I noticed this more when I alt-tab from the game).

So far, the following are what I have tried:
- I use my Sony Bravia TV as display output so I tried using my monitor as well as a different HDMI cable - Same issue.
- Tried using different ports (DVI, DVI + HDMI adapter, Mini Displayport + HDMI adapter)
- Nvidia GeForce Experience application installed a new driver (version 347.09) last week. Tried to perform a clean installation of the previous version (344.75) - Same issue; Also tried a clean install of the latest version but still the same.
- Played around with the Manage 3D Settings in the Nvidia Control Panel - Same issue; Restored to default settings after.
- Tried the Nvidia setting for Noise reduction - Same issue.

I would greatly appreciate any help or advice with this issue.

I am also attaching some screenshots taken to better describe the problem as well as a video of how Dragon Age Inquisition looks like.

Thank you in advance.


Edit Note: A friend of mine corrected me.. She saw the video and told me that the color/s of the blinking spots are a combination of red and green.
