Nt-kernal errors are almost always due to lack of voltage to the cpu. There's multiple reasons this can happen, everything from really bad power at the wall socket, really cheap and unreliable psu, motherboard drivers, bios settings, even windows itself. Cheap power strips can be a major issue.
So it's on you to eliminate as much as you can. This means making sure the pc is clean, I prefer ccleaner from piriform.com. Use both the cleaner and registry tool. This means going to the motherboard website and updating all the chipset drivers and bios too if necessary. This means physical inspection of the psu, exactly what brand and model. This means looking to see exactly what else is plugged into the same circuit as the pc. When was the last time it was thoroughly dusted? Is the dust filter on the psu clean?
