[SOLVED] Worrying startup noise from cold boot - getting longer HELP - Audio included

[mypetllama]

Hi, getting a weird startup noise on first boot each day and it seems to be taking longer each day to settle down. (now over a minute's worth!) All fans seem to be spinning properly and even checked GPU fans are spinning by briefly sticking a finger in there. Any suggestions, maybe PSU? Appreciate any advice.

The system was only built in last 3 months.

sounds like a dodgy fan. With the PC powered off try opening the case and then power on the PC. Try to work out where the actual noise is coming from. If it's a fan spinning up then it's probably the bearings, so replace the fan. Let us know what you find out. Good luck.
