VanillaToast - Did you update to Windows 8.1? Did you use the event viewer to see if Windows will log the error? Without access to the source code it would be hard to assume a memory leak. Memory can be consumed by poor programming. This could be the application or the operating system or a poorly written device driver. DEP prevents code execution for memory that is other then executable code. How much virtual memory and how much free virtual memory do you have? Quite frequently Windows itself is not the problem but poorly written device drivers especially video drivers cause the error you are getting. Just because you have the latest device driver doesn't mean it is free of errors. Please post your computers dxdiag.
