I left my PC on doing IBT tests overnight and turned it on this morning to an error message. However, it looks like the failed run has a massively different value to what it expected (moreso than I've seen in previous failures) and I also realised that the time of failure would have been very close to when I woke the PC up (see the log below). So my question is, could a bug have caused this error to occur when I shook the mouse or whatever to see what the result was rather than it actually failing after 76 (!) passes?

Test Result: Failure.
----------------------------
 
if it made it 76 passes id have to lean toward temp rising during the night or like you said moving the mouse.. now if it was say 10 or 20 passes.. then its may possibly not be stable.. but after 76 passes id say its stable..
 
I doubt my room got warmer, max temps were still in the mid 70s and the sun comes out at like 05:00 this time of year.
 
could of been like you said turning the monitor on.. though what id do just to make sure weather that was the reason or not is to disable all the power saving features like the screen saver, display auto turn off, hard drives.. all that stuff.. that will remove the variable..
 
Well the thing is I don't use a screensaver and I did turn off the monitor manually but I'm not sure about other power saving features, I'll check them tonight.

Since the above runs, I've completed 100 runs successfully with the VCore one step higher so I'll drop it to the same level as in this test and run it again with power saving features off when I get the chance.
 
OK so both 1.21875V and 1.22500V passed 100 IBT maximum stress tests and I got a blue screen whilst doing nearly nothing with both. Any ideas what that could be? The audio playing starts repeating the same ~1s and everything freezes, then about 5-10s later I get the blue screen. :/

Could be a bad Windows 7 x64 RC driver but I am suspicous.
 
I have taken to starting and stopping ibt a bunch before I actually let it run. It opens up more and more ram as I do this and gets closer to 100%. The most I've been able to use on a single set of tests is about 90%. Computer did get a lot hotter than if I just open it and let it run whatever was maximum at that moment btw.
