Sometimes it started with several beeps, sometimes it started with a single long beep. When I restarted my computer the problem seemed to pass till the next time.
First, I suspected I had a virus. I made sure I updated my Kaspersky to the latest version and scanned for viruses with no luck.
I then went to Windows device drivers manager and stopped the speakers service - but still, the beep used to come whenever it wanted. Eventually, I came with the theory that my machine is getting too hot and therefore I get a warning beep. So I opened the case of the PC to make sure my ventilation is working properly - all seemed right.
So, I decided to download this small app named Core Temp. It can give detailed about the temperature of each core of your CPU. It uses information from the CPU itself and not sensors that measure temperature outside the CPU.
After loading the app I noticed the temperature was around 70 degrees. It seems to me a bit high, but nothing unreasonable. So I decided to wait for the next beep to come.
After few days the beep came again. I loaded the Core Temp and was amazed to see that the CPU temperature was on 95 degrees!
I quickly opened my PC case and noticed both ventilation are working properly. So I decided to give a closer look at the hit sink below the CPU ventilation. I noticed a huge amount of dust that filled the hit sink.
I started cleaning all the dust that accumulated there along the time. Then started my computer again and loaded the Core Temp. Then I noticed the temperature was around 35 degrees!
Eventually the mystery was solved: my PC was beeping like crazy, since the CPU was hitting too much and I couldn't tell there was a problem, because ventilation seemed to work properly.
So if your PC starts to beep with no apparent reason, do yourself a favor and give it attention. It might say that something is seriously wrong. Probably your CPU is over hitting and the blame might be more then a low performing ventilation: DUST.
I assume that the dust may have caused 2 major things:
- Less effective hit dispensation.
- Increases the drag of the ventilation and therefore cause it to rotate slower.
When my computer was working hard, CPU temperature started climbing higher and higher till it reached around 95 degrees and the computer started beeping to warn about the hit.
The small difference of removing the excessive dust made the difference for more than 50 degrees! Worth the effort!
