BSODs and crashes during gaming but nothing else stressful.

Like I said, BSODs and crashes seemingly only happen during gaming, usually 2-10 minutes into it. Even benchmarks can't force it to break. It's not a temp problem, the cards are usually around 48C, and the CPU is usually at 45ish. The game doesn't really matter, either. Borderlands 2, Civ 5, and Skyrim all end in reboot death. I'm using the Catalyst 12.11 driver. I've run memtest86+, no errors. CHKdsk yields nothing, nor does Malwarebytes. I had the same problem a few months ago. The only solution was a clean reinstall of windows, and I would prefer to not have to do that again.

Crash Two: again, close proximity.

Crash Three:

And, in the case that it's useful, the past month's worth of crash codes. I can get the rest should it be necessary.

Your dump files are all identical BugCode 0xa0000001 this code relates directly to ATI video drivers
i would recommend to first reinstall latest drivers if that is no help i would go back one version and install them, its best to uninstall old drivers then run http://www.sevenforums.com/tutorials/83814-drivers-clean-left-over-files-after-uninstalling.html to clean out any old bits that can cause conflicts/affect new drivers then install new drivers from here AMD Graphics Drivers & Software step 2 has an auto detect and install option or manually select if your going for older version
