There was a BSOD .....

Code:

BugCheck 124, {0, fffffa800768a8f8, 0, 0}

Probably caused by : GenuineIntel

A stop 0x124 means a hardware error, and the first parameter is "0" that means though the error is detected by CPU, but the source of the error is undetected.

Are you overclocking? As you are getting BSODs, you should stop overclocking and run all the hardware components like CPU, GPU and RAM to their default settings.

Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight.
If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.

Stress test the Graphics Card using Furmark.

Stress test the CPU.

Check if the Power Supply Unit (PSU) supplying adequate power to the computer or not.
eXtreme Power Supply Calculator
Also let us know the wattage of the PSU.

Is the computer hot? Report us the heat of the computer after a couple of hours of your normal usage. Upload a screenshot of the summery tab of Speccy. Alternatively, you can publish a Speccy snapshot too: Speccy - Publish Snapshot of your System Specs .

Let us know the results.

Not overclocking, all components are at their default settings. This is an image I took earlier of the recorded temperatures while the computer was idle: imgur: the simple image sharer

Could the error be caused be excessive vibrations of the CPU Heatsink? The thing is, the bottom right hand post/pin for the fan above the CPU turned out to be loose. I could hear the vibrations (buzzing/humming) and didn't know where it was coming from until I opened up the case after the BSOD. Could the loose pin cause an error like this?

Definitely!!

Take care of it, as soon as possible. Do it at once if you can.

No, to both your questions. :)

A loose CPU pin should not cause any permanent damage. But, one thing you also take care of, the thermal paste. If it is dried out, better you apply it afresh.

And, the crash dumps does not reveal (at least almost usually) any specific hardware failure.

Let us know the situation after tightening the screw.

Lets hope so. :)
