If your system is restarting then there is something fundamentally wrong with it. Nothing in Newsbin can cause a restart by itself, although it may be doing it indirectly by loading a part of the system that is faulty. The fact that you are using the 64-bit version should not be a factor. A system restart indicates either hardware issues or something in a kernel level module such a a hardware diver.
I would suggest that you start by using a memory test program such as memtest86+ to make sure that you have not get any RAM that is failing as that can cause the type of symptoms you describe.
Another thread mentioned that SSD disks can be an issue as some of their drivers fail under heavy load.
