Hello, I’m running Linux Mint 18.3 Cinnamon and since last week my notebook is frozen 2 or 3 times a day. Some of the times I’m able to get it back basically by doing Ctrl+Alt+F1 and then back with Ctrl+Alt+F6 but those are the less. Most of the times I have to hard-reset it. I don’t know even where to start looking to know what can the issue(s) be. I haven’t installed any new application during that period, only the software updates that are suggested by the Update Manager. I use heavily the web browser (25/30 open tabs), so I thought that the issue may come from Chrome, and moved to Firefox, but the computer still dies frequently. Any idea what should I look at or what the problem can be? Thank you.
