I installed ubuntu 16.04 on my laptop a month ago, and about two weeks in, my computer first froze and caps lock started blinking. Since then, it has happened at least 5 times, each with shortening intervals. Each time I had to shut down using the power button.

The freeze happens randomly-did not happen under heavy use (Happened when using only browser, while everything was fine when playing a cpu heavy game), hasn't happened during boot yet. In windows would get BSOD once in a while (every six months, maybe?), but other than that nothing indicated hardware failure.

Here are the things I've tried: - Waiting. 8 hours did nothing. - Updating Kernel (was up to date). - Updating graphic card driver. - Every single thing here: Ubuntu 15.10 and 16.04 keep freezing randomly

Some more relevant information: I have an external wireless adapter (TL-WN7200ND) because my internal one is almost dead (it is disabled). When frozen, does not react to Alt+SysRq+REISUB, alt+sysrq+F, ctrl+Alt+F1, ctrl+Alt+delete

System and computer info: Ubuntu 16.04 LTS, Asus laptop N550JV (4.5 years old), Nvidia Geforce 750M with proprietary driver, Intel i7-4700HQ CPU 2.4Hz

syslog: https://pastebin.com/wmAUQtvn crash happened at 17:38:34

Thank you.

  • askubuntu.com/questions/761706/… the freeze happens randomly, hasn't happened during boot yet. will check if syslog recorded. also almost never happened with windows, so probably not hardware – E. F. Jan 8 '18 at 17:33

  • The log indicates faults with two USB devices. You may wish to move this question to ubuntuforums.org, where gurus can take the time one-on-one to help you probe the problem further. At the moment, looks like freeze-caused-by-defective-hardware...which is indeed what most freezes are caused by. The Q&A format of AskUbuntu means that future users are unlikely to be helped by the question. – user535733 Jan 8 '18 at 19:02
