I just built my computer yesterday and everything boots up fine and runs smoothly. However, I hear a constant high-pitched humming noise (like a dog whistle) coming from my computer. The noise disappears when i start playing any game, which makes me think it might be my graphics card...but I'm not sure.
Here's my build:
Intel Core i5-2500 Sandy Bridge 3.3GHz
CORSAIR Builder Series CX600
EVGA GeForce GTX 560 Ti
G.SKILL Ripjaws Series 8GB
Mobo: MSI P67A-C43
Any suggestions? It's a subtle noise...but drives me crazy.
Could be the anything. Video card fan, PSU fan, any of the case fan(s), hard drive. You really need to isolate the source first. If you think its the video card fan, then check if Nvidia options menu has any sort of manual fan control. Play with it to see if the sound responds (the sound should go lower when you lower the fan speed and vice versa).
Dropping it a small way onto a flat surface should sort out the whine. Dont get over-zealous and try launching it off your roof or anything.
Really. Its the transformers, they do this in everything after a while.
