PC not shutting down.

[SugarD]

No, it can kill the entire system. Every time you force the power off, you are very lightly spiking the boards and power supply in your computer. Although it is not an issue from time to time, repetitive use in a short period is very bad for your system. Same thing goes for excessive usage of the reset button. Only use these buttons as you normally would, else you'll find yourself replacing parts down the road.
