Blender stops responding

Blender stops responding when working on a low poly or high poly project after switching to firefox or any other software to view reference images etc. I then have to close blender and start it back up. This is a new computer only a few weeks old. Any ideas what could cause this?

My pc specs:
CPU: AMD FX 6300
Ram: 16 gb
GPU: Radeon RX470 4Gb
OS: Windows 10 64bit
Running 64 bit blender 2.77a

are you trying to render while switching?

ive heard bad things about windows 10.

are your graphics drivers official and up to date?

Not trying to render or bake anything. My current project has a total of 368 tris so it shouldn’t be remotely hardware intensive. All of my drivers are up to date.
