Computer whistling noise turns off

[jyvsman]

Hello,
If i start look google street view coputer starts whistling and after 4 seconds whistling turn just off. Sometimes it happens when i playing some games. Is there videocard error or PSU another chance that computer clock overheats.
Any ideas?
Thanks
Aleks

More information would be nice.

"starts whistling" ... Dixie?
Does it sound like this?


Or can you tell what part is doing the whistling? Maybe video card? Do you have a video card?

last time i saw this , it was a loose cpu heatsync. but without you opening the case and listening to where its coming from its a guess.
