I haven't tried gaming on the other computer yet. I did monitor temps whilst playing PS2 and they were fine. The game didn't crash, the computer crashed/restarted after I quit the game.

Yes, I've tried both the current and Beta drivers. I should add that when installed in the 2 slots that don't work the fans seem to be working about around 50-60% rather than the normal 10%

Just recently changed from water to aid due to moving house and losing a lot of space. So I got myself a NH-D14 for the CPU and changed to an Asus GTX 670 DirectCU II. Aftwer swapping over the cards everything ran fine for a few hours until my system restarted, of which I heard the boot sounds but had a blank screen (just running WoW). After this happened I took the card out and messed around a little with my the 2 other cards in the system (sound and wireless) and I got it to boot again. Then after playing Planetside 2 for about an hour I left the game only to have it crash on me again and boot without video. I stuck my old card back in the system and it worked first try, so I tried a CMOS clear and it still wouldn't boot. The only way I have managed to get it to boot with the new Asus card is by sticking it in the bottom PCI-E slot, which is right next to the PSU fan so temps are just crap. Just wondering if this is a Mobo or GPU issue, mainly because the slots work fine with the old GPU, but the Asus one still works in a quick test in another system/in a different slot.
