App hogging resources

The WindowServer is the system responsible for processing the graphical elements you see on your Mac's screen. It's one of the elements of your Mac that make it possible for you to read this article and view everything else you see on your screen.

By virtue of the above, the Native Process to macOS can neither be removed not deleted.

Computer keeps crashing >>>

1 - Restart in Safe Mode. This will perform a Disk Repair, clear cache files and only load Apple Software, extensions and fonts. The boot up will be slow and can take some time - Normal.

2 - Safe Mode will also eliminate Third Party Software, extensions and drivers from loading. It will only load the Minimum amount of Core Apple Processes to allow the the computer to function at a reduced Level of Performance 

3 - Does the issue present in this mode ?

4 - Sometimes a Safe Boot followed by a Normal Boot will just put things right.

5 - If not - there could be something in the main User Account playing up. To further isolate this - Set up users, guests, and groups on Mac. Then log out of the Main User account and log into the dummy account and test again if the issue persists.

6 - If the issue is present in the dummy account - then, this appears to be a System Wide issue on the computer.

7 - Download the Application Etrecheck directly from the Developer.

This is a Diagnostic Tool that makes no changes to the computer.

It makes a coherent and readable inventory of both the Hardware and Software used on the computer 

The application is free or paid from added features.

Please add more RAM,

Or, if possible upgrade the CPU,

Or, please add a better+FASTER "swap" solution , (you may see this earlier discussion on swap).

Without apple's "WindowsServer" (aka: Windows X Server) process ... many graphical apps wil stop working or will not be able to show anything on screen, etc.

Find out which app is using more CPU & RAM & swap ... then research on how you can tweak them to reduce such consumption or add addons/extensions to stop them from doing unnecessary things that you dont want them to do,

such as, load "NoScript" , "uBlock-Origin" , "AdBlocker" etc type of addons/extensions.

Reduce various graphical nice appearance related features ... that wil reduce "WindowsServer" activities.

Maximize one app on the screen, keep other apps behind the maximixed app , ... that will reduce WindowsServer process activities, etc.

Windowserver is part of the system. It can't be deleted. On my machine it ramps up when I have a lot of windows open in Safari. I don't think it is the cause of the crashing, only an indicator.
