I'm also having this problem, but I think I may have discovered something.
How many people here use Logitech Gaming Software? I personally have a G510 and a G9x. DebugView was running while I fiddled with CoreTemp and I noticed something peculiar; I could run CoreTemp without issue, so long as LGS wasn't running.
All of my unnecessary programs were closed while running this test in anticipation of a crash - I simply didn't want to lose any data due to corruption and the like. To my surprise and confusion, CoreTemp ran perfectly fine. I could change any setting and apply them, and run the program for as long as I wanted. However, while CoreTemp was running I was unable to start LGS. If I closed CoreTemp, then I could start LGS. As soon as I started CoreTemp with LGS already running, my computer would
immediately hang. Thankfully I disabled the automatic startup feature before doing this, so I was able to reboot straight to my desktop without the need of Safe Mode.
I believe the culprit here is the G15 plugin within CoreTemp, or something having to do with it. It seems to be causing this problem for me, anyway. Perhaps the Win8 version of LGS is conflicting with CoreTemp's plugin, or vice-versa?
Thanks for looking into this. I would also like to test this fix that you speak of, so I'll PM you after I post this. My DxDiag is attached, but my DebugView log is too large, so I've put it on PasteBin:
