I have mentioned in here before that my Acer Aspire laptop running Win7 with 4gb of ram has a nasty tendency to overheat with monotonous regularity.
I have now tracked the cause down to Adobe Flash. Run any application or non-Flash website and the CPU temp is about 60degC, but run a site with Flash on it and the temp rockets to 85 then 90+degC (and it shuts down).
It happens so quickly that a little programme I downloaded to intercept the problem and put the comp to sleep can't keep up!
I have uninstalled Flash and the problem has gone away. BBC iplayer, Youtube etc all still work fine - but surely I'm going to have a problem with something not working?
