My system is OC to 4.4Ghz (stable)
Probably caused by : hardware
Most likely not, and even if it is, it's in the way of troubleshooting. As I have it in the sticky:
1. Revert all / any overclocks to stock settings. Even though we're Overclock.net, and we take pride in our overclocks, analyzing and troubleshooting on an overclocked system is very difficult and will only make things take longer, especially if the overclock is the issue in the first place. You're more than welcome to overclock once again after your issues are solved.
In your loaded drivers list, dtsoftbus01.sys is listed which is the Daemon Tools driver. Daemon Tools is a very popular cause of BSOD's in 7/8 based systems. Please uninstall Daemon Tools. Alternative imaging programs are: MagicISO, Power ISO, etc.
Please do this and if you crash again let me know by following the instructions here - http://www.overclock.net/t/1288510/blue-screen-of-death-bsod-posting-instructions-windows-8-7-vista/0_50
and posting back with the required info.
