Freezing screen when playing games

[Mrmk2gti]

I know theres a lot of forums here about graphics card freezing screens.
But I haven't found anything that can help me.

Info about my computer. First time building a computer.
Processor: Amd A-8 6660k Quad core
Motherboard: MSI FM2-A55M-E33 with integrated graphics
Ram: Corsair vengeance 2x4g DDR3 8g of ram
Graphics card: Diamond Radeon Hd 7770
Power Supply: 750watt

So basically, every time I want to play " Counter Strike " or any game on steam it lets me play for about 5 minutes then the screen freezes for like 10-15 seconds. During the that time I open task manager and stop the game. The computer doesn't turn off im able to open task manager.
Ive tried overclocking but that didn't work, so I turned it off. Or maybe I didn't do it right.

Is my computer over heating?
Is something not compatable?
Is my motherboard not good enough for gaming?

Honestly its frustrating, I don't know what to do.

Lets start from the Begining:

* All your Parts are compatible with each other.
* Your GPU is not the best for gaming but as long as you keep settings Low-Medium youll get a decen FPS usually.


Solutions:
1. Update ALL your drivers (CCCs, MotherBoards, BIOS, etc' - from the Manufacture Site).

2. Download MSI Afterburner and check your GPUs temps douring the 5 mins of gaming. Dont reach more then 75C.

3. See if the phisical GPU fan is spinning, and there is no dust + Make sure thet the 6 PIN cable is connected to your GPU!

4. What is the PSU brand ? is it 80 Plus?


Pls check all those posibilities. Good Luck
