I'm Going to Work on My Computer Today and Take a Day Off.

When I turn on the computer and leave it alone, the screen will always be blue, or the screen will be black, or after using it for a period of time, a problem will occur within a few minutes to half an hour. My head hurts, and I have reinstalled the system several times to find out if there is any cable on the hardware that is not plugged in properly. It's a bit painful, I'll make it up when I have time, sorry.
