Hard drive runs all the time

First, doe sthe HDD light blink or stay on?
If not, then the drive may be going bad.

Possible causes for a lot of disk access.

Insufficient RAM:
For W9X / Me 128MB - 384MB
For W2K/XP 256MB - as much as you are willing to install.

Excess RAM:
There is a bug in W9X / Me where too much RAM (over 511MB) can cause problems.
This is VERY configuration dependant!

Limited free HDD space, or a small swap file:
I like to have at least 500MB of free space on any drive. More is better.
While it provides better 'benchmark' test scores, I do not like using a fixed size swap file either. If you use a fixed size swap file, it should be a minimum of 500MB, or 2X real RAM. (wichever is larger)

Empty out your C:\Windows\Temp folder and use the options in your browser to clear out the temporary internat cache files to create more free space.

Fragmentation:
Boot into safe mode, and run scandisk and defrag.

Too many back-ground applications running:
Every Icon in the system tray is resources being used.
Disable EVERY program that you do not need.
Then, use task manager (Alt-Ctrl-Del) to check for other running programs.

Viruses:
Scan your system!

Ad Ware:
Download and run AdAware from www.lavasoft.de
This program will find and advise you of spyware and adware programs on your PC.
