The memory error is not a memory error due the RAM, it's a bug in the code in some place, then propate to other parts and finaly explodes in another place crashing the computer. This is a typical result of software made using Microsoft's tools and the result is imprevisible. Two exactly same computers with the same Windows and software, one works for weeks without any problem and the other can't run one hour without crashing.

Stupidity also evolves!
