BSOD: D3, ESO, DotA 2, help me nerd!

So, I haven't checked my temps, or cleaned out the rig recently (will do that tomorrow), but it seems like the more demanding a game is, the more frequently I get a BSoD. Sometimes it won't happen for weeks. Today it's been excruciating.

Sometimes if I try to reboot immediately after the computer fans and lights will start running, but then crap out after a few seconds.

Can anyone give me an opinion?
