On my other computer, Sony Vaio Laptop...just recently it's been consantly shutting down everytime I run a big program, or sometimes just shutting off by myself. So I was guessing it was a virus, so I reformatted my computer, since that's the only way I know how to fix it. So in the process of reformatting it, it still was shutting down. So it took like 10 tries reformatting computer till it finally finished. Well, now that my computer has finally been reformatted, everything deleted in C and D drive n' all, my computer still shuts down. Does anyone know the problem? thank you
