Ok I know this topic may have been talked about before but I still want to ask this. Everytime I play a game in xp i get an siren sound coming from the box, why is that? I have looked to clean the fans but it did not help any. This happens almost only when i play games and sometimes when i browse using ie7 in vista. But wheni close the browser or exit the games the sound stopes, can someone please tell what this is and what i can do about it for it is getting very iriritating.

Open the case and see if you can determine where the noise is coming from, see it's the fan on the CPU. If the bearing/s of the fan is bad it could make this noise
The fan speed is controlled by the temp., so playing games which use more resources could cause a rise in temp.
