Whenever I try to transcode a movie or a large video file, my laptop always switches off abruptly some time after the transcoding has begun. I initially thought that this had something to do with my DVD drive but even when I tried converting videos from a hard drive, the problem remained. I've switched from Handbrake to VLC and still the problem remains.
When I opened System Monitor when the converting was going on, the CPU usage is around 100%. Is this a hardware problem or is it something wrong with the software?
