Computer crashes

Soo Well as the title says my computer literally dies on me when I play maple, but I have no clue as to what is triggering it. Something in maple doesn't agree with my computer I guess. It turns itself off after about an hour or more maybe or earlier then that depending on how temperamental my computer wants to be. It will turn itself off I then have to wait 30 seconds or so to turn it back on any earlier and it crashes instantly.

Then when I load maple again about 20 mins into the game it will crash again and last night it was about 10 mins til it decided to crash for the 3rd time. It's only maple that causes my comp to crash to so I guess it's something game related.

It's really annoying me and I have absolutely no idea what to do about it. I tried cleaning the fan, Updating video drivers, Virus Scans, Firewall access.. and some weird free cleaning program call Advanced Care that someone said to use in another forum.. None have actually done anything. Anyone have any ideas of what might be the problem? Thanks.

Edit: My comp has now died twice without maple running but I wasn't on it at the time. So I have no idea what caused it to crash then. I tried playing maple again earlier and it repeatedly turned my computer off every 5 minutes.. This is such a hassle of an issue. I have defragged, run an error check and I reformatted about a week ago, So registry issues should be minimal or none..

This was happening to me with another game (Lunia), and I think that the problem was overheating. Your computer will shut itself down if the CPU sense too much residual heat. It's to prevent fires and whatnot.

Try downloading hwmonitor. It monitors the temperature of various vital system components. If the numbers become high (in Fahrenheit, not sure what they're supposed to be in Celsius) then you might want to consider cooling the computer and just turning it off for breaks.

Otherwise, if that doesn't help, try check your system error logs and dumps. They probably have an error message or an MSQL line error for you to reference; use it to do some google searches.
