issue in Splinter Cell and other games

[Squall_Rinoa89]

I have this annoying as HELL.... Issue when I'm trying to play...

It gives me a bar on the left side of the screen that constantly flickers colors and flashes >.<

Now, I had looked for the SLi thingy that lets you see how well SLI is scaling however... it is most definitely that at all...

It happens in Splinter Cell Blacklist, happens in UT3, Dead Space 3...




Now, mind you i've already done the following...

1) Checked the GPU to see if it was seated propely
2) Reinstalled and installed the game
3) Reinstalled Driver 326.80 Numerous times
4) Cleaned the GPU, Entire PC of dust
5) Power supply is well within the rated limits as its a 850W, 3yrs old and hardly any ware on the +12v rating, +5V @ 5.05, +3.3V @ 3.33V

PSU is the XFXBES Back Edition 850w (the one you guys loved when you tested)

I am now at the point where EVGA is recommending me RMA my 560 GTX Ti, which is the one I have previously RMA'd for it BSOD upon plugging in 2 monitors.
