When you say nothing changed on your laptop, do you mean no updates either with Windows or SW? Also, providing us a bit more info may help - SW version, Service Pack, Graphics hardware/driver, etc.
I'm a bit lost as to what you mean by loading from "Integrated Preview", etc. I don't think that is possible. I think those windows are there only to let you see what the render will look like.
Solidworks Premium 2015 x64 SP 1.1
Intel(R) Core(TM) i7-4700MQ CPU @ 2.40GHz
Nvidia Quadro K610M
Took out the from and added a comma
I cannot load anything, "Integrated Preview", "Preview Window", "Final Render", or "Recall Last Render"
As in these features when activated (clicked on) produce zero results.
I have done renderings of this particular assembly before with no problems.
Even with just a single part I'm having the same issue.
