Various BSODs

[midkemia]

Hi there.

I recently upgraded my computer to the following parts:
Intel i5 2500k
Asus Maximus IV Gene-Z Gen3
Corsair Vengeance 1866mhz DDR3 4GB x4
Asus GeForce 570 DirectCU II

Additionally, my old parts were reused:
Cooler Master M600 PSU
3x various 7200rpm hdds

I installed a fresh install of Win7 64x Ultimate, got all drivers in place (latest from Asus.com), then went to restart the pc by request from Windows Update.
As it shut down, I got an BSOD.

Started up the computer again, tried to run a game, BAM, BSOD.

Went on and tried to figure out why I got them, so I ended up doing a Prime95 test.
It lasted ~30 seconds before I got another BSOD.

Note that all 3 were different BSODs, as you can see in the screenshot following.

I have not touched anything that has to do with OC (yet), as I want to assure that all parts are working.

Here is a screen of voltages/temps from AI Suite II, CPU-Z, aswell the 3 BSOD dumps.

Please help me fix this!

Ran Prime95 again, stopped before anything happened, got the following right off the bat:

Test 1, 6500 Lucas-Lehmer iterations of M12451841 using Pentium4 type-2 FFT length 640K, Pass1=640, Pass2=1K

Worker 1, 3 and 4 stopped right away, all giving this error:
FATAL ERROR: Rounding was 0.5, expected less than 0.4
