Anyone experienced this before?

This morning my casing was vibrating once powered on. I placed my hand on the casing and it feels like the PSU is vibrating and giving out a humming and buzzing sound. Definitely not high pitched coil whine that varies in tone, but a constant low pitched sound.

Not sure if it's the PSU fan inside or some mechanical parts inside vibrating.

PSU going to uplorry soon? :eek:

Will open up and check again.

I shutdown the PC right after Windows boot up successfully and opened up casing. After I checked that nothing seems to be amiss, I powered on again and the sound and vibration was gone.

Now seems normal again.
