Windows 7: Windows 7 random freezes?

Possible solution / fix to this problem.

Yesterday I did a check for new wifi-driver and it seems I found an older version than the one I was running. I downloaded from acer.com/support. Pretty sure this was the site I downloaded from earlier



After driver update I did a 3 hour heavy load test with torrentz, different youtube vids and other multitasks to provoke a computer freeze. To my surprise nothing happened. CPU was running 100% lots of this time and my computer didn't even get to overheated as earlier.

Also worth mentioning is that I haven't used this computer since late may'2012.
Got 3 months of updates for windows7 aswell prior to this test..

Will update this if I manage to provoke another freeze.
