Shut the computer down and remove the battery. Hold the power button down for 30 seconds to 1 minute. Replace the battery, charger and turn it back on to see if that resolved the issue.
This is almost certainly a mainboard going bad -- probably a bad cold solder joint somewhere. It may work for a while but it's likely that someday soon, no amount of fiddling will get it to boot. If the system is in warranty, call Dell -- if it's out of warranty, you're likely to find the cost of replacing a board will be more than 50% of the initial cost of the system - carefully consider your options (a new system might be a better idea).
