When you cleaned the dust out, did you happen to bump any of the RAM
modules, or perhaps any of the cards plugged in to the motherboard?
Re-seating the cards may help.
Have you recently added any cards to the computer? If you have, your
power supply may be overheating. When you blew the dust out, did you
check for airflow through the power supply?
Are you doing anything in particular when the computer shuts down?
Perhaps playing a video-intensive game? If you have an off-motherboard
video card that has a fan on it have you made sure it is turning properly?
Try running the computer with the side panel(s) removed. If the
shutdown doesn't happen, then you do have a heat problem.
