My motherboard or processor started making (or at least I barely noticed) a low hissing sound. Googling around described the symptom with a buzzing or hissing capacitor as the culprit. Could these be the signs of a dying motherboard?
The system has been running fine so far. Just like it always has, just with the added hiss that I probably just noticed.
By the way, it's only audible if I put my ear near the Processors heatsink. And it's not the fan, I already know this isn't mechanical related as the hissing happens when the processor is idle. When there's any kind of activity. For example, when scrolling a webpage, it fades away. The hiss comes back when the processor is idle again.
Should I prepare for the worst?
It's been so long since I've posted here, I've removed my signature since most of what I had here were broken links. Shows over, you can carry on to the next post.
So far, I haven't seen any bulging capacitors, they all look like they are intact.
If you find a capacitor on your board that looks like it's swelling, you want to replace the motherboard before it goes. Otherwise you risk having to buy a new processor as well.
So should I start saving up for a new system build?
Remember kids, once you let out the magic smoke, it's time to get a new circuit board.
Seriously though unless it's the fan, there should be nothing- nothing- making noise on a motherboard or cpu, they're pretty much solid state. The only time you hear hissing on electrical appliances is due to extremely high voltage (Think high tension lines here) or high resistance (most likely a capacitor overheating, but it could be some crap on the circuit board as well).
Googled your board. If you see where those three silverish metalic heatsinks are that's where the mosfets that regulate your CPU power are. Those will make an angry noise if they start to go, and once they are gone the board is toast and it can take the CPU with it.
My advise would be to take the build out of the case and onto your desk, then listen to that area and see if it's making the noise, if not listen to other parts.
