I had all kinds of issues when I started using Fusion 360, and it was down to not having sufficient graphics RAM. The min requirements they specify is 512MB, so might be worth checking that your on board graphics satisfy that. Made me buy a new graphics card in the end, but thankfully something inexpensive, so long as it has 512MB minimum, should do the trick - doesn't need to be anything fancy from what I hear.

Hope that helps
