Hello,
So, I'm really a noob when it comes to computers but since 8 months i've had a gaming PC. But since around 4 weeks now it starts to make strange noices constantly when my pc it turned on. I have literally no idea what this sound is or where it is coming from (listen to the attachment, it is like a clicking/ticking sound) does anyone know or recognise this sound and should i be worried? i've never opened up my pc nor cleaned it.

My specs are:
-OS: windows 10
-processor: Intel Core i5 6400 4-Core, 3.3Ghz
-GRAPHICS card: Nvidia Geforce GTX 1050 Ti 4GB
-hard drive: 500GB HDD
-RAM: 8GB DDR4
-power: 600 watt Xilence Performance C 12CM fan 82+
Sounds norm alto me.
A moth flew into the INTAKE fan. Please ignore the idiotic response above.

It's hard to discern from the recording, but if it's a clicking sound it's very possibly the hard drive. When a hard drive is dying, it MAY make a clicking sound. I strongly urge you to back up any critical data that you don't want to lose. You can replace the hd and see if the sound disappears.+1 Allan. I would also consider the CPU or PSU fans.
I agree, it can fall on the HDD and Fans, I had this before and it turns out my HDD is dying in matter of time. Removing them one by one will do the trick to figure out which causing the sound.
