Game crashing on download?

I can download the game launcher with no problem but every time I try and download the actual game through the launcher my computer keeps crashing. It doesn't do like a blue screen of death, it just freezes. I then try and relaunch the launcher and it doesn't work whatsoever, so then I have to go and try and download the launcher again after uninstalling it. My computer has crashed trying to install this for the fifth time and I have never had this problem ever occur with my PC ever. I've played games for much longer and have had no problems with crashing ever.

Anybody wanna help me out?
