If you have bought a new computer or a mobile device and it crashes all the time, take it back to the store and have it reexamined by experts. If they detect that a factory defect is the problem, they will provide you with a replacement.
If your computer has video problems (such as black screen) when it comes out of sleep or hibernate mode, the network driver's power management settings may be causing the problem.
To change the driver's settings:
Maybe your device crashes or freezes due to lack of disk space.
Check out the Running out of disk space / no space left solutions to learn how to free up disk space.
If your computer crashes while you are browsing the net, the culprit might be an extension. Only if you uninstall the faulty extension, will your computer stop crashing.
To uninstall an extension:
Click on the three parallel horizontal lines on the top right corner -> Add-ons -> Extensions -> Select the add-on you want to delete and click Remove.
Click on the three parallel horizontal lines on the top right corner -> More tools -> Extensions -> Click on the trash can of the add-on you want to remove.
Tools -> Manage add-ons -> Under Show, tap or click All add-ons -> If the add-on can be removed, you'll see the Remove option -> Tap or click Remove
Go -> Go to Folder from the menu bar -> Type /Library and click Go from the menu bar.
The Library folders contain the following folders for add-ons: Internet Plug-ins, Input Methods, Input Managers and Scripting Additions. Move any files within these folders to the Trash.
Note (Safari users): Do not remove Default Browser.plugin, nslQTScriptablePlugin.xpt, Quartz Composer.webplugin, or QuickTime Plugin.plugin because Safari needs these plugins.
If your Windows computer crashes or freezes when it "wakes up" from sleep mode or hibernation, disabling power-saving mode should help solve the problem (but if you use laptop you need to plug in the AC Adapter more often).
To disable power-saving mode:
Start -> Control Panel -> (Hardware and Sound) -> Power options -> Change plan settings (on the right side of the selected power plan - Balanced or High Performance) -> Change Advanced settings -> Expand the hard disk power options, by clicking on the "+" next to Hard Disk.
Change the time listed under Turn Off Hard Disk After to Never. Do the same for the Sleep, Hibernate After options.
