There is one other thing. this caught my eye when i ran speedfan 4.49:
WARNING: bad Winbond($5CA3,$C1) identify (W83627DHG-P,W83667HG)
W83627DHG-P (ID=$C1) found (using SuperIO) on ISA at $290
I have no idea what it means
The GPU temp is showing around 42C, AUX is about 45C, everything else is below 40.
CPU0 fan is between 2300-2350rpm.
Voltages:-- VCore: 1.26V, +12: 6.65V, AVcc: 3.18V
First, what is "Quickheal 2014?"
BSOD's have many possible causes. They can originate with a hardware problem or software.
There are several BSOD codes which appear with the blue-screen information. Here's an About.com link that should have the entirety of the information:
http://pcsupport.about.com/od/findbyerrormessage/tp/stop_error_list_0x1_0x5f.htm
and there should be better sites, better presentation without a whole scroll page of ads. Especially if you build your own systems and overclock, there is an extant list of some 10 BSOD codes published in forums at various web-sites, such as overclockers, tweaktown, HardOCP, and other places. You'd likely even discover a discussion and publication of the list on forums for your computer's motherboard.
YOu say it SOMETIMES avoids the BSODs when you disable "this Quickheal thing?"
BSODs are like a vicious circle. A BSOD with one cause (a piece of hardware, a buggy infant HW driver) can cause hard disk corruption and therefore corruption of the operating system. Do you have any means of telling that your OS is NOT corrupted?
I would think the error message you cite arises from a problem, conflict or failure of some motherboard or add-in card's sensor. The Avcc voltage you cite seems to be in the ballpark -- which way this or that, I wouldn't know.
HOWEVER, IF I'M NOT MISTAKEN BY YOUR MEANING, your 12V+ is only showing 6.65V!! If that is the 12V going from the PSU to the motherboard, I would be surprised your system could even boot up!!
File away one of these possibilities, since I'm not the electronic engineer and someone else may have more insight: bad PSU or motherboard going south.
