Yea your video card is below spec. I looked at your Dxdiag file and did notice your drivers are out of date since 2013. It's a long shot but try updating your video card drivers and sound drivers. I searched nvidia for you and linked the newest driver below for your 540m video card. Your onboard sound is made by Realtek. A simple google search will bring you to their website and nab the latest driver. Updating those two might squeeze enough performance to minimize your crashing. I'm no pro or anything, just figure i offer some simple solutions that may or may not work. Rule of thumb for me is to keep all drivers up to date until said hardware is no longer supported or relevant. But your best bet to run POE optimally and future games without crashing would be to upgrade to newer hardware. Also like Derek said above. Keep graphic slider low and display resolution to a minimum. Your mileage will vary. Hope this helps. Later
