Computer freezes when playing CSGO

[TheThrasher]

Hi! I don't know if this is in the right thread but I have a problem. I play alot of CSGO. Recently my computer has started freezing after about 15-20 minutes. No other games do this, only CSGO. Heres my specs
CPU: AMD Phenom X4 965 3.41 GHz
GPU: Powercolor ATI Radeon HD 5850
RAM: 8.00GB
Motherboard: Gigabyte GA-970A-DS3
OS: Windows 7 Home Premium 64-Bit
I check the GPU temps and it was around 77°. Is that too hot?
