Unusual noise coming from computer

The noise you may be hearing may very well be a fan that is bad or about to go. The fans will start to wobble and make noise. There is a fan in the power supply and 1 or more in the main cabinet.
If the unit has not been cleaned in this amount of time, it is time to open it and clean it out of the dust and cobwebs.
ONLY PROCEED IF YOU ARE COMFORTABLE IN DOING SO.
Unplug the computer from the wall so there is no power.
Open the case for access to the inside.
Proceed to clean the accumulated dust buildup.
BE CAREFUL TO NOT DISTURB ANY COMPONENTS OR KNOCK ANYTHING LOOSE.
You can use a vacuum cleaner for some of it. The rest we recommend canned air to blow the dust out.
Clean the accumulation off the fan blades. You may have to use a Qtip here.
Pay particular attention to the CPU heatsink and get all the dust from there.

In any case it is not wise to leave a fan down as heat is not good for a computer and components. Roadrunners123's suggestion is correct. The procedure is not difficult and it should be performed on a normal basis.
The cost of a fan can range from 5 - 15 dollars for a basic model
Powers Supply can be 40 -120 depending on the wattage
Cost of a can of compressed air is about 4 - 7 dollars

Well, If I'm going to replace the PSU, I might as well upgrade to USB 2.0

Is it a Dell or HP or Gateway?
I can only speak for Dell at this time, but their PSU's are proprietary. There are very few, if any, off the shelf that will fit a Dell.
Any other supply from the shelf will generally fit any other computer.
As for the USB upgrade....What are you looking for? A PSU will not get you USB.
Again, what is the make and model?
What is the operating system?
How old is the computer?
How much memory?
How big is the hard drive? How much free space?
If the computer can not support 2.0 due to limitations of the main board and software, then you can usually put in a separate USB PCI card (provided there is a slot available for the board).
