Graphics driver issue


UE keep crashing my graphics driver. I have an NVidia GT630M and have the most recent update of NVidia drivers installed. The debug crash report is:
Problem signature:

My NVidia error that pops up momentarily says something along the lines of “NVidia drivers have crashed but have been successfully restored.” Unfortunately in the process UE crashes and I lose whatever work I’ve done. Any ideas?
