my husband determined that the fan is working fine but the noise is coming from something else. The normal humming sound of the computer has been replaced by an inconsistent humming sound that can get loud. Any advice? Thank you.

There really are only a few things that can make a "humming" sound from within the computer.
The primary one is the power supply fan. It usually happens when the unit is first turned on in the morning, and then quiets down after it's been on for a while.
The CPU cooling fan could also be making noise. you can disconnect it to see if the sound goes away, but DO NOT run it for a long time without the fan, as overheating will occur.
The hard drive could also make a humming noise. Depending on how severe the noise is, depends on the possibility of the drive failing.
The CDROM could also make a humming noise when attempting to access a CD.
The floppy drive could make an inconsistent noise if the drive is attempting to be accessed when there is not a diskette in there.
If you're comfortable enough, I'd remove the case top, and run the system without the case on it. When you notice the noise, look inside the system to see if you can get the approximate area of the noise.
