I have a T6op which passes all advanced stress test, memory tests etc in lenovo toolbox and is 100% stable on windows xp but is unusable on ubuntu.

I had sound issues while moving windows and poor 3d performance so I disabled kms. Things were a lot better but now getting random freezes and have to hard reset as mouse and keyboard become unusable.I have render video in openshot without a freeze.. Temps are fine..but could get afreeze from just web browsing.
Seems to be a common issue.
Have used Ubuntu since the begining and overcome most problems
but can't find a solution to this.
