I have Ubuntu 16.04 (Xenial) installed on a laptop from 2014 with 8GB of memory and a quad-core processor (Intel Pentium N3530). Once it a while, it freezes completely (I can't even move the mouse) and I must restart it.
I've recently noticed that it's related to how many tabs I have in Chrome − programs without Internet resources don't seem to impact it. The freezing is especially prone to happening when my changes to a form are being synchronised, eg in Google Docs or Quora. It also seems more impacted by tabs with frequent updates like Facebook.
Is this a problem with my network card or with my memory? I sometimes have system monitor open and the memory might only be at 50% sometimes when the freezing occurs. Sometimes I lose Internet connection while still connected to the network. I'm not sure where to dive deeper − which logs are relevant etc? What would I see there anyway?
I heard about memtest but when running it, the results were going fine until my computer inevitably froze.
I used to have an earlier version of Ubuntu and had hoped that the freezing would stop in 16.04, but I guess not.
