I've read many articles and have yet to get a definite answer as to the possible issue and resolution in my case. I've had some problem now for over 1-2 months but it's sporadic. I could go weeks without it happening then days where It's constantly shutting down my monitor with that message. If it was the hdmi patch cord I'd think it would happen more frequently or maybe I'm wrong. I can leave my computer on for hrs with no issue like today yet play a game and 10-15 mins the monitor shuts down with that message. I had my pc in the shop and apparently everything checked out fine.....I didn't quiz the techie as i should have about HOW he tested everything as it continued to happen after he brought it back the same day he returned it lol. then I went over 1 1/2 weeks without incident. The odd part that I've not seen mentioned anywhere is that after I shut the pc down and reboot, I get that 4 note chime that usually indicates that the pc has identified a new component.....which is rather odd. I've not yet tried a new patch cord but I've re-seated my gpu on multiple occasions and nothing. Still goes in spurts. I'm beginning to think that my gpu is simply getting old and is overheating perhaps(it's a radeon (R-200 series)card. Rather long in the tooth no doubt. Today it's Lotro, i log in, play for a few mins and during a cinematic part of the game boom! happens again, system idles for 1 hr after reboot, no problems, i play a different game, boom! happens again after 10 mins. sigh I'll still try the patch cord switch but I really fear it's my gpu as mentioned already.
