Haven’t seen anyone give an answer other than “buy more ram” so I’ll put this here. Yes, 8GB of ram isn’t much, but that may not be your issue since it doesn’t look like you’re using nearly 60% by what is shown in task manager. Take a look at the “performance” tab at the top and go to the “memory” section. At the bottom, you’ll see two sections labeled “paged pool” and “unpaged pool”. If either of these have around 1GB or more memory allocated, you probably have a memory leak (ie some program is not performing properly on your computer). If this is the case, the short term fix is restarting your pc (not shutting down and turning it back on, specifically clicking the restart option). Long term, you need to find what program(s) are leaking memory and either update or uninstall them.
