Computer/Monitor Crash

Title: Computer/Monitor Crash

Version: 3.1.3

OS: Windows Vista 64bit

Java Version: Java7 Update 10

Description of Problem:

I am making some computer doors using motorframes and computers from redpower, I very simply have my computer attached to a IO Expander that then delivers colour coded wires to the motors. My computer is then attached to a monitor in which I can simply type commands "open" "close" and so on. But sometimes I enter the monitor and my game crashes immidiatly with no error message popping up ot white screen.

No Idea where error log is so here it is all.
