I'm really at a loss on this one.
I have recently (as in yesterday) purchased a Galaxy GeForce 210 graphics card, purely so I can run my 17" Dell LCD beside my Samsung 24". I'm running Windows 7 Home Premium, 64-bit.
Everything seemed to be working fine - I installed the card, installed the drivers that came with it (which it says are Windows 7 compatible) and away we went. The 17" plugged into VGA and the Samsung into DVI.
However, after running for a little bit, I started to notice that every now and then (read about once or twice a minute) the Dell would flicker or flash a bit. The best way I can think to describe this is imagine you have made the Windows task bar about a third of the screen tall, and then suddenly shrunk it and your graphics card couldn't keep up - so you get a momentary flash of black before the desktop shows. That's what is happening to me.
It doesn't matter what application is running - or even if no application is running - and I can't reproduce it on demand. However, I've tried the following things:
1) upgraded the drivers from nVidia.com - now running 8.17.11.9745 - no change
2) rebooted my machine no end of times to make sure that's not the problem - no change
3) booted my machine back into Vista Ultimate 64-bit, loaded the same drivers from nVidia - the flickering doesn't seem to happen!
4) disabled the second screen in Windows 7 - the remaining single screen doesn't flicker.
5) re-enabled the second screen - now the Samsung screen is the one doing the flickering.
6) searched what seems to be the entire internets! - still can't find a solution!!!!!!.
Anyone out there got any ideas on how to solve this?
