Hello,

I've bought a new motherboard and processor roughly one month ago. The motherboard is a ASRock Z77 Extreme 4 and the processor is a Intel i5 3570K.
After reinstalling Windows 7 I tried to play some games and started to notice that my games kept either freezing or crashing randomly. A tray icon popped up telling me that the display driver has stopped responding and recovered succesfully.

I opened Windows event logs and saw that amdkmdap was responsible for the crash, which turned out to be my graphic card's driver (ATI Radeon HD 6870).
After removing the drivers with Display Driver Uninstaller (formerly known Driver Sweeper) and installing up-to-date drivers I kept freezing and crashing. I also ran Memtest86+ to see if my RAM had anything to do with it, but no errors detected.

Now one month later I decided to buy a new power supply and a new hard disk with all the money I had and for just a few hours I thought the problem was fixed. I played a game for 30 minutes and the game crashed again...

Does anyone have an idea what causes these amdkmdap crashes? I would really appreciate it if someone can help me out on this one.

UPDATE:
I've replaced my current graphic card with an older one (Radeon 5770) and the error still persists.
Could it be that they have delivered me a broken motherboard? Can three RAM sticks cause this error when the motherboard is designed for dual channel?

UPDATE 2:
Adding another set of RAM solved the problem. The motherboard manual said it supported my previous RAM set though, so it's still kinda weird. So if you have this amdkmdap error, try switching the RAM with another pair if you can't think of another solution.
 
What make and model power supply are you using in your computer? I see that you purchased a new one, but if you didn't get a power supply of sufficient capacity, you may be near it's limits.

Have you overclocked any of your components at all?

AMD recommends a minimum 500 watt PSU for use with an HD 6870.

I bought a CoolerMaster GM Series G650M.
Here is a link http://www.coolermaster.com/powersupply/gaming-gm-series/g650m/
My previous one had 500 watt.

I have not overclocked any component. AMD Overdrive is also turned off as I've never needed it to perform better than it already did.
