My computer shut off and won't turn back on. No lights, no sound, nothing. I had just updated my virus protector (Trend Micro) and was doing a full scan. I believe it was during the scanning that it died. I wasn't in the room, so I'm not exactly sure what happened after I left. When I came back in, the screen was black and it won't start. Any suggestions on how to get it back up and running??? 🙁 Thanks.
