Why does my computer keep restarting?

So on the weekend I put together my first computer build and yesterday I received my copy of windows 7 64 bit and installed it. Yesterday it was performing fine, I was able to install drivers, antivirus (avast), download programs such as steam, and even play some Minecraft.
Today when I was watching youtube it randomly froze for a few seconds, and restarted on me without warning as if someone unplugged it from the wall. This happened multiple times doing things such as browsing the web in roughly 20 minute intervals. I figured perhaps my cpu was overheating but it was around 40 degrees Celsius and my cpu fan was fully functioning. My computer kept restarting more and more frequently, and now my computer has a hard time even getting to the windows desktop without restarting. When it restarts I sometimes a blue screen that flashes saying to check software and hardware but that is all I can read.
My question is does anyone know what the problem may be, and how can it be resolved. Is it hardware related or software? Should I just re install windows and wipe my hard drive clean?
My build at the moment is: Intel i5 4670, Asus Z87-A, G.Skill Ripjaws 8gb 1600 MHz, Rosewill Hive 750 watt, Seagate Barracuda 1tb hdd.

Perhaps I could one from a friends build and connect it. The Rosewill Hive series is not marked as "Haswell Ready" but I read on multiple forums that running it with a Haswell chip would be fine, it may just not fully utilize the low voltage states that Haswell can perform.

I'm not sure what auto or adaptive voltages are. I did not want to mess with overclocking so I didn't read up on voltage much. All I know that I haven't touched anything with voltages, and in my bios it says my voltages are right around 1.0 all the time. I have seen it fluctuate a little to around 1.02 but I assumed this was normal.
