Below these two "beeppppp" sound was using "A" wall socket. It can listen when I turn on the wall socket(haven't start pc) or shut down pc. This sound makes me headache cause the sound is too sharp. The sound also is come out from pc there. Besides, i change it to "B" wall socket, the sound still has but is small sound, almost like no sound.

This is Coil Whine from the GPU. Sometime caused by a cheap Power Supply or just the GPU itself doing coil whine.

What's the PC specs of your system?
