Delayed Crash

[Swatking1996]

So my friend and I have been playing the tekkit pack for quiet some time now, and whenever we encounter bugs they are generally an easy fix but I can't seem to find any forums based on this error/bug/crash:

Launch game

Select world

Launch World

give it maybe 5-10 minutes and it suddenly crashes with no error message.

It simply crashes without a valid reason.

this started occuring after my friend switched his mainscreen to his TV instead of his laptop monitor but after changing things back to how they originally were in hopes of solving the problem, it continued to happen.

Anyone else experience this problem yet?

Any known way to fix this?

If unknown, then would you recommend deleteing and reinstalling the game?
