I don't really know where to put this thread so i'm putting it here,also english isn't my main language so i'm sorry if i'm hard to understand.

My Pc Specs:
MB: MSI Z77-G43
CPU: Intel i5 3570k
GPU: Zotac Nvidia Geforce 660 ti Amp! Edition

I also have a "Creative SB Audigy Value 7.1" sound card.

I bought this system about a year ago,assembled on my own and had no problems since now,about a month ago i replaced my Xigmatec apache 2 cooler with a cooler master vortex 221q and i had no problems until recently.
I was playing DMC devil may cry and the game suddenly froze,as in sound started looping,screen went white and while mouse and keyboard light were on commands like alt-f4 and ctrl-alt-del didn't respond.

I reapplied the thermal paste on my cpu and changed the cooler back to stock cause vortex didn't really fi?t nicely as it had kind of motion when i tried to move it.
And now i'm trying to play Batman Arkham Origins and its doing the same thing.

My tempatures are:
CPU Idle: 40
CPU In Game: 65 to 70
GPU Idle: 36
GPU In Game: around 70

I also live in a hot place as my room tempatures are between 30 to 36 degrees.

What can be causing this? Can the GPU's thermal paste have melted?
 
I also have a sandisk readycache 32 gb ssd that i use for well caching and a Western Digital Caviar Blue 1 TB hard drive,i also use a ps3 controller with ds3 tool but i don't think this issue has anything to with it.
 
And what about power supply?Does it have the wattage, the number of PCIe power connector? Not sure how pins it needs but check if it has enough power delivered to the gpu, and try cleaning the gpu or psu.
