So, I've been writing a Word document in Microsoft Word 2013 for 3 or 4 hours so far and got to 6th page. The document consists of a lot of equations, about 5 per page, and now it has become impossible to write anymore. Typing a single letter takes 5 seconds to process and the CPU fan speeds up during processing. How can I continue writing my document and using equations without sacrificing performace, or, at least, speeding up things a bit to a workable speed? I have a pretty powerful computer (i7 4700K CPU and Sabertooth Z87 mobo) and I don't think it has anything to do with my PC specs because I can run 10 other apps in the background and none of them freezes during the Word processing time.
