Solve : Computer freezes followed by high pitched hum from mobo? |

Answer» hey guys, Thinking it's a bad capacitor.. as I continued to try to fix the thing cause it was driving me insane, the sound started ton happen without the system freezing In the power supply right? This motherboard has higher end components SOLID state and electrolytic caps and I would doubt that one of the smaller electrolytic caps would make such a noise on this motherboard. I'd run it with the side panel off and when you HEAR the noise, listen for it coming from the motherboard or rear fan area of the power supply to locate it, but I believe if its a cap making the noise that its 99% with certainty with this motherboard coming from the power supply. If you have the speaker connected to the speaker pins on the motherboard that is where I would look for the sound before the power supply making a noise like this, however many people do without connecting the PC Speaker to the Front Panel Pins on the motherboard, and if its disconnected then the PC Speaker cant be the cause and I'd look at the power supply as the cause. Lastly.... I have heard of hard drives that make strange noise before failure. The noises can range from a groan, to a buzzing, to a ping sound like a pin ball machine. So with the side panel off of this system when it makes the noise, I'd also check around the hard drive to see if that is the cause. If it is the cause, then backup all data immediately and check into getting a warranty replacement for that drive as for modern drives should be somewhat silent operation.The sound happens with no speaker attached, the psu runs completely silently with no issues at all. I have done some research and seen that some gigabyte boards have done this so it makes sense to me . The noise is right in between the ram and cpu area.cool to hear that you pin pointed the area to be the motherboard. And this is the first time I have heard of one of the smaller caps making a noise that loud. Maybe the cap was stuffed with incorrect polarity at Gigabyte and its venting as for generally Gigabyte makes good quality boards. Best of luck in board replacement and problem going away. Thanks for the help guys! This thing has been driving me crazy!Were all MBoard standoffs in place properly ? ?...could be harmonic resonance... Quote Were all MBoard standoffs in place properly ? ?...could be harmonic resonance... Yeah I was going to suggest checking to see if the CPU fan was humming causing resonance, but the computer freezes wouldnt be cased by resonance unless its vibrating like a jack hammer with a loose connection somewhere to sever from vibration. Dampening the resonation with hand on case or on side of cpu heatsink etc would stop the noise or quiet it some if it was resonance.I thought it was resonance and checked for it when it was freezing by STOPPING the cpu fan (gently of course), it didn't help at all, I sent back both the cpu and mobo to Newegg today, hopefully I'll hear back soon****UPDATE**** So Newegg denied my request for my motherboard fml.. they're still reviewing my processor though. I called gigabyte and they said it could be my graphics card which makes no sense to me because the sound isn't coming from there. I remember the Temps were fine as well. I'm so confused and frustrated guys, now I gotta wait for both my processor and motherboard to get back. |
