Windows 7: Strange constant flicker on LCD Monitor - help?!

Is it possible for you to disconnect the PC from the monitor and attach something else (like a DVD player) that would send a video signal to the monitor to determine if the flicker continues? That way you could be sure if the problem is actually in the monitor, or the PC. Even if not, it would be interesting to know if the flicker appears on the black screen without a picture. You could also open the monitor settings so that an image would be on the screen.

In a television, a steady rate horizontal or vertical scrolling would point to a bad ground or video interference due to shielding issues. If you can connect the monitor to another PC, you can quickly determine if it is the monitor or the PC. I believe a horizontal scrolling would be less likely with a monitor failure.

I'm not sure! I'll certainly check that. Weirdly (and also mildly annoyingly), I haven't noticed the problem occurring since I started this thread!

My video card details are on my spec, what d'you think of the size? It doesn't just happen when playing games, when the PC is sitting idle with the desktop showing, it can happen then.

I've got a black desktop background set at the moment, so I can spot the problem when it comes back. No sign of it at the moment.

Okay, I'll give that a go and report back! :)

Okay, here's the latest. The problem went away for a wee whiley, but then it came back. I think I might've got to the bottom of it, however! I was having trouble with my audio (that's another story, involving a 5-speaker surround sound system plugged into one audio socket via a splitter), and I was fiddling about at the back of the PC, then my monitor cable popped out. I had trouble getting it back in again. Then I discovered that the adaptor (SVGA /VGA Adaptor 15 Pin Female to 9 Pin Female - my video card only has the VGA socket) had a bent pin. So I straightened it out and plugged the monitor back in. That got me thinking: might the flicker be caused by a dodgy adaptor?

What d'you guys think? Thanks for all your help so far, by the way!
