When playing games, i find that the game freezes for a while (maybe 10 secs) then returns to normal. I have been told it is due to overheating. I was thinking of buying a new heatsink and fan but then i noticed that it was hot around the area where the power supply is. Now my question is whether i should replace my 250W power supply for a higher one or should i buy a heatsink/fan? I want the overheating to stop so i want the best solution. Thanks in advance.
