For the last few days, my monitor has just suddenly been going black. I have to restart my computer manually before anything will come up again. This happens with seemingly no reason, since it'll just happen when I'm browsing the net, playing a game, or doing nothing.
The system still runs, but no audio comes from my speakers as far as I can tell. The speakers aren't attached to the monitor either. Normally, if my system shuts off and the speakers are on, they make a loud popping sound, but it's not doing that now.
My computer definitely isn't overheating (I have SpeedFan running and always pay attention to the computer's temperature), and I haven't installed anything new or done anything differently. I'm not sure what it could be, and my event log doesn't seem to list anything suddenly acting up.
Not sure what information I need to post, but it's an XP Pro (2004 version, I believe), HP Pavilion, Windows Media Center Edition.
