crash PC crash when GPU under load

[cooldude190403]

Hello, First off this is my first post here so sorry if this is in the wrong thread.

I recently got a GTX 750 ti.

I upgraded from an AMD Radeon 6870

Whenever I put it under load I get a complete system crash,
the best way I can describe this crash it is as if someone just pulled on my plug in my pc.

I think it maybe the PSU causing problems however I can't be certain 

 

I am happy to provide logs if needed.

What I have tried:

Uninstalling the Old graphics card drivers.

Reinstalling the New Graphics card drivers.

reseating GPU.

 

Specs

CPU: Intel Core I7 950 at 3.07GHz

Motherboard: X58A-UD3R (latest bios)

Graphic card: current GTX 750 ti (Old: AMD Radeon 6870)

Ram: 18Gb

PSU: 700W Thermaltake litepower 

O/S: Windows 7 Ultimate

Yes it runs just fine with the Radeon 6870, I only started to notice problems when I switched to the 750 ti.

Thanks for welcoming me.

I tried War Thunder, Team fortress 2, Counter-Strike Global offence and cinebench, and had the same problem with all of them.

Ok when you say Delete anything pertaining to the AMD GPU what exactly do you mean?
