Processor : 2.93 GHz Intel Core 2 Duo
Memory : 8 GB 1067 MHz DDR3
Graphics : NVIDIA GeForce GT 120 256MB
Software : OS X 10.9.5

I keep running into a problem whenever i start a game it will go fine for about 30-60 seconds and it will start to flicker on the bottom half of the screen only. if i don't close the game and let it continue to flicker my iMac will freeze and crash, but when i power it back up it makes the internal sounds as if its turning on and makes the annoying power up sound but the screen stays black.

The games i am trying to run are Dota 2, CSGO, D3 RoS. it works perfect for hearthstone, but anything else just crashes
Thank you for any help in advance:)
