I sometimes hear a soft zooming sound from the pc-case. It's sort of a vibrating sound, as if the sounds is from a fan. It's usually not hard, but it keeps going on for a long time. A few times, these vibrating sounds were quite loud, for a short time. What could this sound be, and how can it be fixed? There aren't any warning messages from windows.

it could be one of your fans spinning up at times when your pC is getting warmer than other times (like when you are using the PC for games etc..) or it could be your hard drive...though that's less likely to be a constant sound...if you can find EXACTLY what the sound is comming from you'll probably have a better idea of what it is...but that's not always easy to do....a good idea would be to go to your local computer store and get a couple of cans of compressed air and blow all the dust bunnies out of the computer to make sure it's clean...make sure you hold the fans still (like the CPU fan and the fan on your graphics card if it has one) while you blow air on them so that you don't burn the bearings out by making them spin too fast

I noticed that the sound often occurs when a quite heavy game is being played. What does that mean?

it's probably one of the fans in y our computer...either the one on the graphics card or the one on the CPU...get some canned air from the store and blow all the dustbunnies from inside of your computer...make sure tho hold the fans still when y ou blow the air so that they don't burn out from spinning too fast....do all of this with the computer off and unplugged of course
