Strange loud high pitched noise coming from p.c.

Does anybody have an idea as to what could be the cause of this? Just wondering before I start unplugging things one by one.

It's quite loud, but nowhere near the volume of the graphic's card squeek (i.e. when the power's not plugged in). I've not put anything new inside for a few months and it's just started today.

Cap on the mainboard perhaps, idk?
Hard disk drive ?

Power supply?

It doesn't 'sound' like it could be a hard drive, all of mine run fine on SMART checks. They're also fairly new as well (though of course that's really not a good way of looking at it).

Hmm, it could be a capacitor on the MB. I think I might have to look and see if there's any bleeding.

Edit - I'd prefer it to be the PSU just because that's less work. Though lol how on earth would I test whether it is or not? :confused:

which motherboard is it?

I get capacitor squeal from my gtx260 when running folding@home. It could be that.

Well that's my hearing officially shot - it's my monitor
