Default Potential CPU overheating?

Hello, lately I have been having a bit of instability, in particular, doing processor intensive things.
I recently got a BSOD, all that I was able to record was "IRQL_NOT_LESS_OR_EQUAL"
googling this BSOD revealed that it can be anything, but usually points to processor, in particular overheating.
I decided to do a Prime 95 test while monitoring my temps with Everest. My temps were hitting 45C max out of their 72C limit. After a few more minutes, my motherboard temperature disappeared and then my CPU temp was 63C. Then, in a second or two, my temperature went back to 43C.
I have gotten an error once before, and once while writing this about my CPU fan not working. Luckily it just appeared and I took a SS of it.
Just noticed something, my time has switched to military time.
Here is a link, the picture is too large.
I have a bit of dust on my heatsink, do you believe that this dust could be stopping the fan? Perhaps the fan is failing?

1. we need a stop code. The 0x000000** code

2. It's not an overheating issue. It sounds like a chipset driver issue or failure.

3. Is the fan spinning like usual? If it is I would ignore that error the motherboard could be sending confused messages.

I know that you need the stop code, if I am able to replicate this crash I will surely record it.
Edit: Yes, the fan is spinning. When I get the CPU fan not spinning message (have gotten it twice that I can remember) I open my case and look at the fan, it has always been spinning.
I doubt it will help, but I have the information that windows gives you after the crash
Problem signature:

Just as good.

This file (C:\Users\Alexander\AppData\Local\Temp\WER-44787-0.sysdata.xml) failed causing this code.

0x0000000A

This is all I could find tied directly to that file so maybe check it. usbscan.sys PAGE_FAULT_IN_NONPAGED_AREA ERROR

I don't believe that Everest report. It is showing your CPU temps as 12C (54F). It is impossible for conventional (fan) cooling to cool a CPU cooler than the ambient (room) temperature and the air inside a computer case being blown on to the CPU's heatsink is typically several degrees warmer than the room temperature. So unless you are using extreme alternative cooling (e.g.; refrigerated liquid), or your windows are open in the dead of Winter and your room is freezing, those temps are wrong.

IRQ indicates an interrupt problem, typically caused by failing hardware, corrupt driver, or conflicting drivers. Any errors in Device Manager?

Well, look at it. Is it stopped? Certainly a clogged fan can run slow, but if the fan is clogged then surely the fins of the heatsink are too. And that would be bad.

I will take a look at device manager when I get home. Also, I do not remember the exact ambient temperature of my room, but it is usually 50F-68F.

Edit: I forgot to mention, I have recently OCed my RAM and Processor. Perhaps this is causing these problems? One other thing I did; I installed quite a few security programs. Ad-Aware, Malwarebytes Anti-Malware, Spybot S&D, SmitFraudFix, Eset antivirus, Zone Alarm Free Firewall, Macafee Stinger. That is all that I can remember atm.

If your room temperature is truly 50F, then those temps are possible. But, brrrrr!

I don't think Smitfraudfix is for Windows 7. I don't see where Stinger is either. I use Microsoft Security Essentials (MSE) and Windows Firewall. That's it except I am behind a router too. I periodically do supplemental scans with MBAM just be sure all is good. But it is only in on-demand, not in real time. And it's scans find nothing.

You should definitely stop overclocking until this is resolved - assuming that is not your problem in the first place.

I down clocked my RAM as the motherboard does not support speeds above 1333. This seems to have stopped all abnormalities that were happening.

Well, then it sounds like that might have been your problem. Thanks for the followup.
