Hey guys. Been experiencing seemingly random BSOD's for the past few weeks, and completely unable to solve the problem myself. It happens from a minute or two after startup to after 3 or 4 hours or working, and sometimes doesn't crash on intensive apps like Furmark.
I'm running a Lenovo Y400 with the newest Nvidia drivers, and have attempted rolling back and uninstalling with DDU but no success.
Any help would be very greatly appreciated, I'm sitting in the middle of exams with a timebomb computer.
Sorry for thedelay in responding. There just aren't that many people who do BSOD analysis,so at times we get a bit overwhelmed!
All your latest driver verifier dumpfiles blames Probably caused by : nvlddmkm.sys ( nvlddmkm+cbb76 ).
This is as you mentioned the driver for your nvdia card.
But you have a Lenovo Y400 and it seems that your model has customized drivers from Lenovo. Uninstall your current nvdiadriver and install the windows 8.1 driver from Lenovo from here Drivers and software - IdeaPad Y400 Notebook
Advice: install also all the other windows 8.1 drivers for your system.
Daemon Tools (and Alcohol % software) are known to cause BSOD's on some Windows systems (mostly due to the sptd.sysdriver, although I have seen dtsoftbus01.sys blamed on several occasions).
It is known that daemon tools sometimes also causes problems with graphics /video.
Please un-install the program, then use the following free tool to ensure that the troublesome sptd.sys driver is removed from your system (pick the 32 or 64 bit system depending on yoursystem's configuration): New link (15 Aug 2012): DuplexSecure - Downloads(pick the appropriate version for your system and select "Un-install"when you run it).

You guys are doing a great service over here, no need to apologise!
Well, I did the driver uninstalling and reinstalling and the errors persist. Through a lot of troubleshooting I've identified the problem is almost certainly a loose GPU - being that when the laptop is touched or twisted in a certain way, the crashes are induced. And I was really hoping it would be software...:shock:
