Power Supplies very seldom, if ever,

make such noises. Try ferreting out the real source of the grinding noise.

Yes it could be a bad fan in the Power Supply and that should be very easy to determine. The remainder of the components in a supply are not mechanical in nature and thus can't make grinding noises..

replace the power supply

replace it. I see PCs everyday that that PS failes and turns the system into a nice boat anchor. if your fan bearings are worn enough to make noise then you probably have had some heating issues already. With those come burnt windings and unstable power to the system. Power supplies are pretty inexpensive (unless you are running a gaming system), just replace it to be safe.

So there's no need to worry about that stuff. If there's a power supply problem, the fuse will go.

Replace, ASAP

If you have a fan installed in the psu, its probably biting the dust, literally. Forget about replacing the fan itself, so the whole psu. I suggest you replace it ASAP. Delayng it will only increase the chance that when the psu goes it *may* take something else with it or fail when you least need it to. replace with a higher wattage unit of the same type/class. If you have 300W psu, think 400W or better and decent namebrand will be stable compared to cheap offering even if labeled higher wattage, they're not stable on prolonged high demands.

I had a power supply that did the exact same thing

and it was the little fan. So I went to a website (I think it was tiger direct) and bought a new fan. Take out the old one and make sure you get the right one.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
