Constant crashes, please help.

Firstly hello all, I'm new here, but was active over on the 7 Forums. I have ran into my first ever problem with a build, I keep getting crashes on the load screen of all games. The Error message is that pesky Kernal 41, event category 63, everything driver and BIOS wise is fully up to date.

My specs are:
I5 4690k ( stock )
MSI Z97 gaming 5 Bios 1.5
2 x R9 290's ( Stock )
4 x 4gb sticks Team Group 2666 RAM
4 x SSD's
Superlower Leadex 1000w
Fully custom water cooled

All items are new, to this build. So far I've checked all connections, and removed any cable extensions just to be safe, I've ram Memtest86 and all comes back fine. Also Valley benchmark runs about 50% of the time, the other times it causes a crash also. It isn't actually blue screening, it is just kicking me out of the game, and restarting, but then again it could be but the restart process is so fast I'm not seeing it. Cheers guys please help. I should mention that, it happens with Crossfire enabled or disabled, and the temp on the GPU, during Valley when it was actually running was 45 max, and the VRM's were, in the 50's, one strange ge thing though according to GPU-Z, during Valley the GPU usage was at " 0 "
