Sounds like you need a new fan.

Lets just do some diagnostics first, can you do the following:

# Ctrl-Alt-Del and bring up the Task Manager.
# Click the "Performance" tab.
# Take note of the (roughly) amount of Physical Memory available
# Open MS Word, write down the new amount of Physical Memory available
# Open Dreamweaver as well, write down the new amount of Physical Memory available.

Few questions I would like to ask:

1. How much RAM do you have?
2. Processor spec?
3. Cooling components (fans, heatsinks etc)?
4. Any error message or visual thing before it shuts off?

Report back, thanks.
