Dear benefactors, I'll make up the remaining chapter tomorrow-my computer had a bit of trouble today

Do any of you benefactors know what's wrong with this damn computer? Whenever I shut it down, there's a chance it won't boot back up, and I have to keep restarting it. I even reinstalled the operating system four times today.

It's the kind of thing where, after I turn it on and it passes the motherboard's self-test, the screen lights up faintly, but there's nothing on it.
