Is there anything I can provide for you to differentiate between the two? I personally doubt it is a hardware problem although hardware might contribute to the problem. It is because I can still normally browse the web with other browsers, like for example Iceweasel and I used to be able to browse with Epiphany (some year ago for sure).

Let me describe the exact user perception of the problem on the most frequent case: playing an HTML5 video. A user launches the browser and navigates to YouTube. There he plays an hour long video. At random moment (it might be in the middle of the video or more closer to the end) the mouse pointer is starting to work harder. After a while the video freezes and audio repeats in a short loop (2-3 seconds). Afterwards the whole graphical environment freezes. Then the fans begin to work louder. Eventually the system shuts down. Presumably due to being overheated by too much load on processing.
