Re: What's going on?
It sounds like something could be on the system forcing a shutdown...kinda like a virus, but I'm not 100% certain. I don't know if you know how to access all files on the computer...like the computer has a log somewhere of what programs have been downloaded or what documents were saved. I'd try to find that and if you find anything that has been added recently that you weren't aware of doing, delete it into the trash folder, then delete the contents of the trash folder. That may help!
