It started today after about a month using the new motherboard which is from Gigabyte Technology Co., Ltd. Model 965P-DS3.
If I do not connect the 2x2 12V the PC does not run, although the fans all work, however the video card does not display. Therefore, I have to plug this connector in order for the PC to work properly. As soon as it is plugged in, (12 VDC from the Power Supply), a terrible chirping sound comes from the motherboard. Everything in the computer works fine (I am using it to ask this question), but this sound is annoying. It is like one of these big fluorescent lamps power supplies when they buzz, but a lot louder, like about 30 or 40 of these at the same time. The noise is not coming from the fans or anything that moves. It is electrical in nature. It is not the speaker either. Will I have to replace the Motherboard? Any way to get rid of this noise? Thanks in advance.
