I got a really annoying and worrying sound coming from my desktop. It start at random times, plays for random time (might be 10 min constant might be just a beep every 10 min). Attached is the noise recorded with my cam. I hope you can point me to what's wrong because searching around didn't help much.
First of all, no one [other than you] has any idea what we are working on; post ALL of your exact system specs. Specifically the exact mb, exact cpu, exact pw supply, etc, etc. If this is a big box system ie dell, hp, whatever, then post the make and model.
Next have you checked your temps? If not, then do so and post those here. You can access this info in the bios or most mb mfg have purpose designed software for monitoring temps and voltages however I cannot tell you which one to use since I do not know what mb you have installed.
Temperatures while idle (measured with Speedfan):
CPU: 36, GPU: 45
while under load:
CPU: 53, GPU 55
(all in Celsius)
I want to note that there are some more temperatures in speedfan named as "Temp1, temp2, temp3" ranging from 25 to 60 as I typing this post, not idle, but not really under load). Also temps named, "local", "remote2" and "HD0" with temps 38,35,30 accordingly.
I cannot find your pw supply listed anywhere with that part# Is that by chance a pw supply from a dell server?
Next since this is a gigabyte mb, download easytune from the support page for your board. Post all of the info ie voltages, etc. Speedfan often returns flaky info and unknown temps.
Do you have any warnings enabled in the bios ie overtemp, etc?
Other than the noise, does the system run correctly?
I don't think it's from dell. Not sure. It says:
RECOM (tm) www.RECOM.nl
PE-M600 modular power supply. Power Engine M600 ATX12V V2.2 EPS12V
and below that is a table with voltages, watts etc.
At some point I had an overheating problem and I turned those warnings on. When the sound started I thought it was from these warnings, so I disabled one by one to see which one was causing it. Turned to be that even with all disabled back, the sound was still going. So I guess it wasn't them.
Until recently the pc ran smoothly even if the noise (period of 1-2 days). However since the noise is extremely loud and annoying I can't run it for long when it starts. Today it did something else unexpected, the monitor lost signal and after few seconds the system became unresponsive (the 2nd part is my guess from youtube sound that was playing in the background got stuck). Only way to bypass it was to force shut down. That happened twice in a period of 30 minutes, and haven't occurred since then. Other than those, it runs totally smoothly.
Temps and voltages look good. Can you open the case and use something like a long straw, long thin screwdriver, etc to hold against parts to see if you can ascertain where the noise is coming from?
While you have the case open, give your mb a very close inspection with a bright light. See if you find any capacitors that look like the pics below.
The best I can to locate the sound is exclude the HDDs, the SSD, the DVD-Drive and the fans. Meaning the remaining possible sound sources are motherboard, gpu and psu.
It will take some time to determine if they are bad, i got no experience on such stuff
I got an interesting note. I downloaded a program called Heavyload that stresses different aspects of your system. When I ran different tests I noticed that the sound starts 1-3 seconds after the CPU test starts, and immediately stops after the CPU test stops.
I should have added that sometimes you can smell something that smells like ammonia. It will be a slight odor. I can never smell it since I must have the worlds worst sense of smell. Others may be able to smell leaking caps [not me]
I think it is indeed an overheating warning. One that I didn't notice that was enabled in BIOS. When CPU reaches above 70 degrees Celsius it starts beeping. Problem solved, I know what this annoying sound is and how to deal with it. However something else appeared.
Since this might be not related to the beeping, I do not know if I should open a new thread or keep posting here. Anyway, as I mentioned somewhere above, sometimes the screen loses signal and the system becomes unresponsive. Now this happen extremely often. Especially when I try to play games. Surely it's not monitor's problem because i tried a 2nd and still happens.
Yes, it can be caused by overheating. Fix the overheating problem first then we can move on to the second problem [if it still exists]
Open the case and give the hsf a good cleaning with a can of air. Check the four mounting push-pins to make sure they are tight and the hsf is fully seated. Now pw ON and see if it overheats. If it does, you are going to have to pull the hsf and clean all parts with 91% or higher alcohol. Reassemble using new thermal compound.
Note for intel type hsf, I always recommend pulling the mb out of the case to R&R a hsf. This is so you can turn the board over and check the push-pins to be sure they are fully engaged.
You can mark your own thread as solved using the button at the top of the page. I will mark this one for you.
