Computer turns off without warning

[Aspen]

From few days i am facing some issue with my system whenever i am trying to run any program like Windows media player or Windows Movie Maker my computer turns off itself without any warning message. If i try to run my computer in safe mode it's working fine over there adn at the same time i have also changed my power supply but still facing same issue. Can anyone tell me what would be exact problem.

There are many reason for your computer turns off without warning the most of the basic reason would be Power supply, have check for the same and at the same time also verify the processor heat sink is properly connected by disconnecting and reconnecting the heat sink. If the processor heatsink is not properly it will not keep the processor cool causing the computer to overheat and this would turn off your computer.

It might happen that you computer might being infected with a virus because of which whenever you try to run any program your computer gets shut down. If your computer seems to be turning off when executing a certain program at specific times in the day, it could be infected.
