You should never disable the page file, no matter how much physical memory you have. Just set it to system managed and it will usuyally sit around 1-2Gb usage.
For explanations as to why you shouldn't disable it;
The way windows handles virtual memory hasn't changed much up to Windows 7. Windows 10 changes it up a bit but you still shouldn't be disabling it completely.
