screenshot of system monitor 1screenshot of system monitor 2My ubuntu linux 16.04 freezes randomly while i browse the internet. It happens sometimes at opening google or at times opening a pdf file of 50 mb. It happens just at any random site whether light or heavy. Only thing that works is forced shutdown. I have tried magic sysrq key combinations but they only work when my os hasn't freezed. REISUB also doesn't work during the freezed period.
