I have been experiencing intermittent freezing problems in Starcraft 2 and COD4. These freezes will come at various times and last for various amounts of time (usually around 3-5 mins). I checked out temps and my cpu idles at about 40c on all cores with its max reaching 71c. My GPU usually idles at around 70-73c and its gotten up to 87c. Could any of these be causing it?
