replacing computer power supply module?

[nswef]

My HP pavillion pc model p6120f has a noisy fan that appears /sounds as if it is in the power supply box. I have dusted, compressed air it and think maybe I damaged the fan with the compressed air. My question is: If I order a new power supply is it very difficult to put in? " I was reading about some kind of "glue" to be put on before re attaching the wires. I'm not totally inept with wires, I replaced something on an old computer without any problem, but I am not sure about that glue or coating. What do you think computer people? " Any ideas of good places to order a new power supply?

There should be no glue involved. Only thing I can think of regarding that is when you replace the processor (CPU) you need to put thermal paste on it. Which is often claimed to be trickier than it really is.

A power supply is fairly easy to replace. When you take the old one out, note all the wires and where they are connected to. There is usually a big one that goes to the motherboard, then there are those who go to your harddisk and possibly graphics card. Take the time and prepare by looking at some Youtube videos on the subject.

As for good places, really depends where you live. Online retailers are easy because you can compare costs. But you might get a good deal at a local computer store too. If you look up some prices and go in to ask advice you will soon see if they are trying to rip you off or not.

Please post a link to where you read about this glue?
The only think that even should look like glue, was mentioned above, and that is the thermal past if your replacing the fan on the processor (not the same as the one in the power supply). I've built computers for quite a while (built my first Pentium, upgraded systems before that), and only once have seen any glue in one (person hot glued their connections, before mailing it to themselves, cross country, it didn't make it because I saw it in a store that buys damaged, shipped goods). Guy wasn't too happy the shipper sent it to an auction.
What I normally have to worry about is some pc's use a non standard power supply that requires most people to get an adapter. From looking up the specs on what you listed, that shouldn't be the case for yours.

Thanks, it was thermal paste that concerned me. I don't know what it is or what it does, but it seemed to be important. But not for replacing the whole power supply? Thanks again.

Thermal paste, helps transfer the heat from the CPU to the Heatsink, so the fins and fan can disperse it.

The power supply has connectors that have a little lever (not the proper term) that helps lock down some of the parts. Other connectors (power for dvd, hard drive, etc) are keyed so they only fit one way (don't force things)

Thanks for the going locally suggestion. I did find some places, not open today, but I'll call Monday and see about getting a replacement. In the meantime I'll check youtube and other instructional methods.

Thanks for the advice to go locally. I talked to the woman today and will take the tower in on Wed. when I go to town. They have the part, it will take 30 min. or so and worth the money! Save my 5 year old computer!!! I would have never thought to even call a local if it was not mentioned here.
