Hi i was wondering if someone could help me with a problem? My computer when it becomes hot sets off an extremely loud fan, this noise is fine during the day but at 2 in the morning it wakes the whole street up. The fan seems to always go off when a game(such as the games aol provide free) is being played. It reaches 62oc and blasts out to all and sundry. This is a recent phenomenon as i have had several marathon sessions over the past two years of mahjong garden (which is hardly halo in-terms of graphics usage) without the fan being as loud as this. I have a Compaq presario sr1000 and i'm extremely limited in my computer knowledge so any help would be most welcome.
