BSOD while PC was idling (BCCode 116)

Didn't think it'd be long before this rubbish started happening again...

So after upgrading my PC (apart from the graphics card) all was well until today, a good 2 weeks after doing so, I suddenly get a BSOD after I thought everything was fixed. Codes and stuff attached, system spec in my profile. I made sure to update all my chipst/USB/etc drivers the second I put the PC together.

I did notice that somehow my Catalyst Control Center somehow updated itself to 12.4 from 12.3 ...don't know if that has anything to do with it. Also it's been unnaturally warm for England...GPU is cacking itself at around 53 degrees C, dunno if that's bad or normal?

"It's not a true crash, in the sense that the bluescreen was initiated only because the combination of video driver and video hardware was being unresponsive, and not because of any synchronous processing exception".

Since Vista, the "Timeout Detection and Recovery" (TDR) components of the OS video subsystem have been capable of doing some truly impressive things to try to recover from issues which would have caused earlier OSs like XP to crash.

As a last resort, the TDR subsystem sends the video driver a "please restart yourself now!" command and waits a few seconds.

If there's no response, the OS concludes that the video driver/hardware combo has truly collapsed in a heap, and it fires off that stop 0x116 BSOD.

If playing with video driver versions hasn't helped, make sure the box is not overheating.

Try removing a side panel and aiming a big mains fan straight at the motherboard and GPU.

Run it like that for a few hours or days - long enough to ascertain whether cooler temperatures make a difference.

If so, it might be as simple as dust buildup and subsequently inadequate cooling.

I would download cpu-z and gpu-z (both free) and keep an eye on the video temps CPUID - System & hardware benchmark, monitoring, reporting

I stressed my GPU - nothing happened. So I'm assuming it's that damn crappy software AMD likes to keep churning out...again.

Distinctly possible. BCC116 is often heat, power, vid card,etc.

I stuck an extra case fan in my PC just in case it's the heat of it, and made sure everything was firmly plugged in on the graphics card. As I have a 750w PSU I don't think it's the power, but I did notice the fan really seemed to be having a hard time before the PC rebooted - does the graphics driver regulate the speed of the fan?

The driver typically does not regulate the fan speed. Make sure nothing is blocking the fan such as power wires, dust, etc. There is some software installed with the graphics card drivers that may regulate fan speeds, so check that. Catalyst Control Center/AMD Vision Engine Control Center are the usual names.
