Moved GPUs rig, now unstable

[AmDD]

I moved one of my mining rigs to better heat the house and now it will lockup all the time. Before the move I never had a single issue with this rig but now it locks up a few times a day. The only change I made was I moved it from a mess of GPUs laying out of a half open case into a plastic milk crate. Nothing else changed.
Running bamt 0.5 from a USB drive.
3 5850s .

Any thoughts?

I found after a physical move I had to readjust all my overclocking settings. Not sure why but the settings which used to be stable no longer are. I find the less I disturb the rig itself and the less downtime it has, the more stable it is. Starting it up again after downtime is the most precarious time of all and when I've had hardware failures as well.

Same. I had a rig that ran for just over 2 months with no issues. I rebooted the host rig and on reboot I had 7 of 8 GPU cores. That 8th core never came back regardless of how much crap I tried. I think I've had 4 5970s die this way. I'm down to 12 5970s and I'm determined to only shut them down when I plan on permanently shutting down.

Really? I'll look into the overclocks, thanks for the tip. Thats strange because the room it used to be in has 2 modminers and another rig with 4 gpus in it. The room was never cooler that 80F and now where it is at it stays around 70F.
