The Noisy Screen Saver
-
Hi, I've made a screen saver in C#, and everything works out fine. The only thing that bothers me is the noise made by my computer while the screen saver is running. A few seconds after it comes on, the computer begins whirring and making a lot of noise... This problem is fixed when I increase the interval for my Timer object, but the animation becomes choppy. I would be perfectly happy with the screen saver if I could just get the darn computer to stop whirring... Any suggestions you guys? Thanks, Max

Can you figure out what is whirring? 1) Hard drive? 2) Cd/Dvd drive? 3) Fans? Most likely culprit is that you are loading something from disk (like your images for your animation maybe?) and you're doing this every frame of the animation. Check and make sure you are only loading from disk once at the beginning.

its just HDD noise, this mostly happens in SCSI HDDs. When you will run the program it will look like that it created a physical timer :laugh: If you do not want noise, just change the hdd.

If the noise is comming from the speakers, you've got EMI noise entering the audio channel (audio card, amplifier, speakers, ...) from somewhere on the motherboard or video card. There's really nothing much you can do about it unless you want to start replacing the case or hardware with better quality shielding on it.

As you have seen by the replies so far, you have to be a lot more specific about your computer and the noise that it's making. Is it a desktop or laptop? Can you identify if the sound comeps from the fans, the hard drive, the CD/DVD player or the speakers? The fans can be noisy at high cpuy load, especially in laptops. Hard drives can make some noise, but usually not that much. A CD/DVD played makes quite some noise at spin-up. Some speaker noise due to disturbance from other circuits is common, which can be noticable at high volume settings.
Despite everything, the person most likely to be fooling you next is yourself.

Thanks to all, I'm sorry I wasn't as concise as I should have been... A few seconds after the screen saver pops up after the set time of 1 minute, there is a whirring sound from the back of my CPU. It is a desktop computer, and I'm not completly sure, Simon, what it is that's making the sound. If I had to guess, I'd guess the hard drive, but I'll check again once I get home. Your suggestion that I was loading an image on every frame of animation was one that I had thought of, unfortunately... I am loading several images, however these are loaded at the beginning. Would drawing these images on every frame have the same effect? I have double buffered the form and my timer has an interval of 2, I believe... This is rather fast but I want the animation to be smooth... The only reason the whirring is a problem for me is that I don want to turn the screen saver off every time I go to sleep haha.

Does this happen with all screen savers or just yours? If it happens with all it could be that you have indexing set up to run while the screen saver is active. Or some other similar task.
