I have Solidworks 2014 Premium installed on a Lenovo Thinkpad W550s running Windows 7 Professional and I've only been using the laptop for a few days. Solidworks continues to crash every 5-10min for no apparent reason. It doesn't seem to be associated with any particular action on my part, and I don't pick up on any patterns that would give me clues to why it's crashing. The files I'm working with are about as simple as you can get, just a few 2D sketches and some basic features. So far the only thing I have thought to try was to install the Solidworks approved drivers for the NVIDIA Quadro K620m video card.
