Weird things when PC is put to sleep.

Hi forum. I'm not really sure where to post this, so hopefully I'm in the right place.

So I bought a new computer about 3 weeks ago, and in those 3 weeks I've had a quirk twice when putting my computer to sleep. What happens is; My monitor goes dark as it should, my keyboard lights go out, and my mouse light goes out as well. However, my tower lights remain on and the fan keeps running, and its at this point that trying to wake it nothing happens. My keyboard is still dark and pressing keys does nothing. My mouse light comes on, but moving it does nothing. And my monitor does not show any display coming from the video card. I have to hold power button and reboot for my PC to come back.

My computer is as follows;
ASRock 787 Extreme4 ATX motherboard, intel core i7 quad, 8GB ram,Gigabyte GeForce GTX 760 videocard, corsair pro series power supply, cooler master hyper 212 evo heatsink, in a coolermaster cosmos SE case. Running windows 7.

Any thoughts?
Thanks in advance.
