E-Machine & a humming noise

Hello,
I have an E-Machine 333K and for the past three months it has been humming and sometimes acting up, as in shutting down or freezing. My brother fixed the shutting down/freezing part and I replaced a small fan (CPU?) because it had two broken blades. I did not replace the heatsink (?) that the fan was attached to. Did not know how to. I think the problem is actually coming from the large fan that is attached to the ceiling of some enclosed device that is attached to the ceiling of the computer (educate me?) and was wondering if I need to replace that fan (what is it called?) or something else. Your advice would be much appreciated. Thanks! X.

 

I believe your talking about the Powersupply? The box with wires coming out of it? Although I've never seen a Powersupply with a fan mounted on the ceiling of the box, so I could be wrong. If you have a big techie-friend guy he could pop open the Powersupply for ya, but even some hot-shot Network Tech's won't break into a Powersupply- It voids your warrantys and you might 'trocute yourself on the thing. Most Powersupplies have your run-of-the-mill 80mm fan connected to the board with a three pin connecter (some older ones I've seen are just wired to the board, though). Installing a new one is pretty easy if your accustomed to the environment. You can get one of these things at BestBuy for like...8 dollars?

 

Thanks,
I guess I meant to say that the fan was on the bottom of the Power Supply. (sorry, sorry, my fault) But do you think that replacing the fan will stop the humming noise? I could do that part (grin..I think) or is the entire power supply a problem. I am not worried about a manufacturer's warranty, don't have any. It's just me and the computer at a stand-off. X.

 

Hi boxake,

You can clean the fan with qtips and compressed air. With the air,
be sure to hold the blades in place so that they do NOT spin when you "blast 'em".

maybe this is will help.
