I found my monitor would crash and reset on various websites that used rich streaming media like netflix. I found it was my external monitor that crashed.
Check if you have Citrix workspace installed. Uninstall it.
If you need to reinstall it then reinstall it from the command prompt using
CitrixWorkspaceApp.exe ADDLOCAL=ReceiverInside,ICA_Client,AM,SELFSERVICE,DesktopViewer,Flash,Vd3d,WebHelper,BrowserEngine
YAY no more citrix indirect display adapter. this fixed my issue.
