PROBABLY the wrong section, please tell me if so

Hi, my laptop has been overheating alot lately, since i bought Garry's mod (GMOD) which was at a night before, that one hour it ran perfectly before i went to bed, the next day it started to overheat/get very hot at the bottom, i have no idea what could cause this problem, since i could play TF2 even though it wen't hot sometimes, Here's my specs:

My Laptop is a Acer ASPIRE 5750G

  • Intel® Core™ i7-2630QM 2GHz with Turbo Boost Up to 2.9GHz
  • NVIDIA® GeForce® GT 540M, Up to 1760MB TurboCache™
  • 15.6 HD LED LCD
  • DVD-Super Multi DL drive
  • 6 GB DDR3 Memory
  • Acer Nplify™802.11b/g/n
  • 640 GB HDD
  • 6-cell Li-ion battery


I'd appreciate if anybody would peek in and take a look and try to help me sort out this problem

Thanks.
