Strange squeaks from system unit on two different PC
Situation is following: we have a simple 3D demo, where unity logo shows up, than simple terrain is loading (resolution of the screen is 1024x768). Terrain does not have any objects other than skybox and 2 sprites. Sprites are NPC prototypes that circle through a simple waypoints. As soon as logo comes up, system unit begin to squeak (very strange sound), and video card begin to work in a very "hard" way, just like we have a modern game based on unreal 3 engine with tones of hi-res textures and millions of polygons in camera view but we do not, its just terrain and 2 sprites. This continues to a moment when tester calls inventory screen (png as background and sprites as items). After that, squeaks dissapear, but GPU still have bad times. This happens on a two diffirent configurations:
1) i5 760, GF 460 GTX, 450W power unit, Win7 x64. PC Speaker on
2) Core 2 Duo e8600, GF 9600, 400W power unit, Win7 x32, PC Speaker on
Loudmask Have you read my post? You think, 460 GTX is an old videocard? And what about graphics? I said, we have only PLAIN TERRAIN and 2 SPRITES ON IT! By the way i send this demo to some people who have different configurations, from old dual cores CPU's and GF9800 to i7 processors and 480 GTX cards - and they have not this problem.
Statement In fact i dont have PCI-e soundcard, just built in motherboard type. But you discribed those noises a lot better than me. I didnt mentioned that i also sometimes have this scream in my headphones, but this happens time to time after some restarts of .exe file. But mostly it came from system unit but i cant say precisely what cause it. I dont think its PC speaker.
Interesting. The squeak sound, is it audio noise output by speakers? I actually have a related problem myself, not related to Unity3D but about any other 3D application. However, it is not output that squeaks. It's input (mic recording). I think it is due having my PCI-e sound card too close my graphics card. For reference, the sound card is Asus Xonar Essence STX and video card is a GTX 460. The sound that is sent to my input is a very eerie, haunting, screa$$anonymous$$g sound that makes you think there is a monster in my machine.
And the sound varies in pitch with frame rate. Lower frame rates produce a growling sound while higher frame rates produce a screa$$anonymous$$g sound. As I play any game, the sound oscillates with the fps, yielding a quite odd experience for the guys on the other end of mumble :)

I had this squeaking too and saw that my GFX card(ATI 4870 HD) was running on 90%+ hihg levels but only when running my project outside the editor. Back then I encountered this when doing basic DirectX graphics too. The problem was solved by limiting the framerate (don't ask me how did i do that back then) [this was the story of my life sry]
so I looked up the documentation and found that this solved my problem: http://unity3d.com/support/documentation/ScriptReference/Application-targetFrameRate.html I just set it to 60 and haven't had any problems since then and I'm more than fine with a framerate around 60.

You can do one of two things:
Try not to make your graphics too complex. Allow mipmaps of your textures and shorten the amount of polygons.
Upgrade your video cards.
