Whistling noise

Please help, I just spent a lot of the money I earned as a private during Operation Iraqi Freedom (Phase I-II) on a 2005 Honda Accord EX Coupe Manual and this is driving me crazy.

Manual Transmission 2.4L 4 cylinder.
It's got 34000 miles on it.

My car is making a very high pitched whistling noise, a continuous beep that increases in pitch and volume with RPM.

Noise is present when:
-Clutch is depressed and car is in motion in any gear.
-It starts around 1800 RPM and is loudest when the RPM's around 2000-2750, and when I'm moderately accelerating.
-It's continuous and doesn't go away over time (even after hours on the road).
-It's somewhat faint but I can definitely hear it, on a noise scale of 1 to 10 I'd say a 2 or 3.

Noise goes away when:
-The noise goes away completely when I push down on the clutch and cruise on neutral while moving at any speed. I can rev the engine at this point and there is no whistling noise.

Noise chirps temporarily when:
Sometimes it chirps when the road condition changes and I go over soft bumps but it'd come right on a level road.

Thanks in advance.
