I have an issue with my PC suddenly loosing all power and turning off. Naturally, I suspected the powersupply, but it appears to not be the case.
It seems to only happen when I use Firefox or Chrome and - as far as I recall - only when watching flash videos (Flash ver. 188.8.131.52 )
I tested by also running the mint liveCD and it also lost power when watching a Youtube video. I can't recall this having happned doing any other kind of activity on the PC.
Have any of you ever seen this before?
