BSOD 0x116 cudaminer

Hello.

I recently realized that whenever I stress my GPU (GTX 570) using programs like cudaminer it comes down burning and crashing. It doesn't take long for it to do so and this is strange indeed, as I can recall having ran cudaminer for ~30 hour period with nothing happening. The cause is probably not caused by heat, as I have water cooling installed and even with cudaminer the GPU temps rarely reach above 60 celsius. This thing seems to be more or less consistent, as it happens between 5 and 10 minutes of running cudaminer. I suspect dust, so I started using compressed air and lots of bits came out indeed yet the issue remained. Nvidia drivers and BIOS are up to date. Should I just open it up and start cleaning it thoroughly? Attaching minidumps.

Thanks for quick replies.

And please don't laugh for trying to mine on Nvidia. I know about the pathetic speeds.

Please help.

PS. Actually one bsod is different. Attaching this one too.

Eh, since there is little interest in reading my reports, could at least someone direct me in the proper way? The BSOD occurs not conventionally, like the screen going blue with an error message. Screen goes black and the small screen on my keyboard stops showing any reading for a moment. I believe that this might be PSU related, as the GPU temp is 50 degrees, fans look clean and I don't see any issue with any software being outdated. Am I on the right track here?
