Keep getting BSOD - 0x00000124

[CENTER]My PC started freezing, so I decided to reboot it to factory settings. But now I am getting a BSOD. I have tried different Nvidia drivers (including latest) but that doesn't make a difference. I have also update sound and direct X drivers. I have run lots of malware and virus scans, done a memory test and checked HDD for errors. Everything was fine. All windows updates are up to date. I used the program on here to create crash logs, I have attached. Iv also attached an autoruns .arn file.

Here is the BSOD code - STOP: 0x00000124 (0x0000000000000000, 0xFFFFFA8005592028, 0x00000000BE200000, 0x000000000005110A)

I should also add that the blue screen trigger percentage is as follows:
idle or doing little = 5%
browsing internet (no videos) = 10%
watching videos = 60%
online videos = 25%

plus there is an overclocking profile but I have set overclocking to default and it doesn't help, iv also tried 4 different overclocking profiles and still no different.

Any help would be greatly appreciated.

All of the memory dumps give the WHEA_UNCORRECTABLE_ERROR code. This code is usually hardware related. Many of the dumps reference GenuineIntel as the source of the problem, however one of them was able to show the problem originating in GCACHEL2_ERR_ERR (Proc 0 Bank 8) which is your L2 cache on your intel processor. Please undo the overclocking you have described. Backup important data and run the Prime95 CPU test.

Actually, Proc and Bank don't refer to the CPU per say. These are registers the CPU uses to communicate with Windows error handling. Proc is a Process and Bank is a stack of registers.

I would still run the CPU test and while running, monitor the voltages supplied by the Power Supply (PS). A weak or failing PS is a routine cause of CPU failures.

This is my tower Chassis - HERE

My temps sit around the 27 - 35°C when idle

The 12v line is pretty low. It shouldn't vary from 12v by more than +/- 5%. I don't see the 5v line listed. Set your clocking back to default and re-post another voltage snip. Is the one above at idle?

Bugcheck 124 can be exhaustive to point out due to generality of its problem...
here's the detailed breakdown of your BSOD log

Based on this, I would say your L2 cache was busted.
However, other kind of failure is still possible, so I'll ask someone else to have a look

Besides overclocking, as pointed out by carwiz, bad PSU could be the cause, messing your hardware's voltage and such.
