Windows 7 BSOD System_Service_Exception ntoskrnl.exe+ 72b69

you have a lot of very old drivers installed and some brand new drivers.
your machine is pretty old so I would start with running memtest86 and confirm you memory has not failed.

i would then boot into windows and remove both of the overclocking drivers until you figure out the cause of the problem.
(see the drivers below)

if you still get bugcheck and don't find a cause, you will want to run verifier.exe to see if it can find a driver that is corrupting your memory.
you might just look into updating the old software:

the system bugchecked because of memory corruption.
This can be cause by drivers that over write data belonging to other drivers, over clocking software, bad RAM timings/bad ram.
