I have a relatively new computer that I have built. in the last few weeks this strange noise pops up every now and then. I cant identify where it is coming from, its seems to randomly come and go and I'm fairly sure its not the fans. its almost like a creaking and it can change its intensity and rate of creaking randomly. I've got an audio clip attached, if anyone knows what it is I would really appreciate the help, its getting quite annoying.
