Major GPU Freezing Issues

[Scurie]

Okay, so pardon my speech it I get too out of hand but I am more than pissed off as of right now.
Previous GPU: Nvidia GTX; 650 Ti
Current GPU: MSI GTX 760 Tf 4gb
So after this upgrade my games were acting a bit wonky, low frames... getting choppy... yada yada nothing too serious and It seemed to go away after about a week almost as if I had to break in the GPU. Now; I can load in a game like let's say CS:GO. I can join a game and right as I join in BAM it starts to cycle through a loop of whatever was happening right as I loaded in, like if someone was reloading I will just hear the reloading sound clip over and over again, the game will freeze and absolutely fuck my computer. Like actually fuck it. My task manager won't work and I have to completely restart.
What I have tried doing;
Re-installing the games.
Re-installing the drivers.
Putting the GPU in what my mobo considers 'safe-mode'.
Nothing has helped. Sadly MSI's support line isn't open on weekends so I will be contacting them on Monday but for now any help or information is much appreciated.
Thanks,
Scurie.

Is the 760 factory overclocked? If so, try opening up MSI Afterburner and dialing the core and memory clocks back 100 MHz. Then see if the issue persists.
