Hello guys. I have got a 'new' pc its almost over a year old now and since the beginning i have heard a weird sound from the pc when i start it up. The sound is only like for 2 seconds and after it it completely goes away. I don't know what it is and didn't really bother looking at it but now im starting to wonder what it is? When i restart my pc its silent. I think its just the fans starting up but i im not really a hardware expert on these things.
