Power Supply Unit's fan is coming apart, it's been doing it for a while now. Every time it's rebooted I have to tap/ hit it to get it to spin up, It's like it's coming off the bearings or something., so now I don't turn it off very often. If I'm not around it and windows does a reboot the PSU will start making a loud sound and there isn't nearly enough air passing thru it during that time.
