Like i said in my first post. The machine has been working fine until 19th
when i applied the updates and then wham it started behaving odd, after a
particular long winded scan by the automatic updates process. I know my
machines behaviour pretty well given i live on the thing all day and having
had my last laptop go down the same route its a bit odd. So i doubt very
much its dust and the like, i keep the area pretty clean arounnd this
machine. The behaviour when CPU usage goes up is also different as it starts
to ramp up the fan almost as soon as CPU starts to climb it used to wait for
a while and then only when it got above say 30% would it kick in. The odd
blip wouldnt start the fan racing where as now it does, and it takes a while
to calm down again.

I did start looking into the power and processor policies on my old machine
think maybe something corrupted those, but havent bothered on this new one,
thought i'd try the news groups first now having had two machines do the ame
thing figured others must have too. Luckily its relatively new setup i could
get the thing wiped and start again.
