for some reason ive only heard this from people who video edit..that, there computers [the tower] spark and there motherboard blows up..is this the result of video edditing?..what can be done to prevent this? why does it happen?
Video editing is very strenuous on hardware. If something is of poor quality or being overtaxed, like a power supply, it may cause it to fail. But simply video editing isn't going to kill your computer.
.. hehe ... yeah; the stories you've been hearing about refer to older Server Towers and their lack of Air Circulation. Water cooling systems do help. but for the most part, any air-filtration unit forcing Cool Air into your computer can prevent overheating .. just remember to replace your filters every three months ( or take an Air Hose and blow-out the Dust from your computer every three months ) and you'll never have that problem
