Computer freezes followed by high pitched hum from mobo

[nickdangelo61]

hey guys,

I'm having a serious problem.. I just built a new pc and after windows loads, the computer will work fine for about 10 minutes. But every time I try to install a driver or just randomly, the computer will freeze and a high pitched hum noise will come from the computer itself. I'm almost positive its coming from the mobo and since I have a gigabyte motherboard it would make sense as I have heard gigabyte motherboardss have had these problems. I have an RMA case open with newegg but I just want to make sure my speculation is correct. Thanks!

Specs:

AMD FX-6350 3.9GHz 6-Core Processor

Gigabyte GA-970A-DS3P ATX AM3+ Motherboard

G.Skill Ripjaws X Series 8GB (2 x 4GB) DDR3-1600 Memory

Seagate Barracuda 1TB 3.5" 7200RPM Internal Hard Drive

Zotac GeForce GTX 960 4GB AMP! Edition Video Card

Thermaltake SMART 650W 80+ Bronze Certified ATX Power Supply

Also, I had to send in my serial number sticker on my motherboard box for a mail-in rebate, but I do have a copy made of the sticker.. would Newegg still accept my RMA

You ssure its not the PSU humming / ?

Newegg should still do the RMA as they have records of your purchase...

[nickdangelo61]

Positive its not the psu, sound is coming right near the processor/ram area, ram is fine though ran memtest with no errors

[patio]

RMA the board then...

[nickdangelo61]

Gonna rma the board and cpu just in case

If it happens when the system freezes, it may be coming from the system speaker. Another possibility is bad capacitors as they can apparently cause odd sounds.

Another possibility is that your computer is humming simply because it forgot the words.

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.

[DaveLembke]

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...

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.

[nickdangelo61]

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.
