My computer completely shuts down every time I render my project. Usually it could be prevented by unplugging the power chord, and working from only battery power. But one time, when it shut down, it never came back on correctly. I opened Premiere after a strange recovery-after-start-up and I got the "blue screen of death." I then wiped my computer completely, and all my memory is free. Downloaded Premiere again. For my first 5 minute video, everything was working fine, but when I started a new, longer video, it shuts down during rendering again, only I couldn't prevent it with the power chord at all. Is it a problem with my computer or the program? How do I put a stop to it once and for all, and end the madness? I feel like I've tried everything I could do myself.
