Ok, so I have a user who we've just deployed a machine for.
He can work for about 30 minutes, and then his screens just go blank. Like, nothing from the computer registers. No freezing, no blue screen, no anything. Nothing in the error log, no kernel dumps, nothing. Computer can be immediately restarted and has no problems - screens come up, Windows runs, everything is happy. For about a half hour.
I checked out his temperatures, they're like 30C, so it isn't that. I was thinking it might be a power supply, or video card issue.
Does anyone have any suggestions or insight about what can cause screens to go dark after 30 minutes? Note, the computer is still on when this happens.
