What exactly is happening?
1. When your game fails, do you get an error message or does it just crash when you start it up?
2. When your computer fails...how exactly is it failing? What happens to your computer upon installing and/or trying to run FH?
I'd suggest fully uninstalling FH on your Lenovo and reinstalling it. Run it without downloading any markings, items, textures, etc. and see if it opens without crashing. It could be one of the modifications your downloading that's crashing your game, I know there are a few that don't work with the new update such as some animations.
