Hi, I have a 21 inch Dell monitor - D1626HT and it flickers every so often. I'm using it with Rage Fury Pro/Xpert 2000 Pro. Has anyone encountered this problem and is there a way I can fix it? I had the screen refresh rate set at 56 Hertz and I switched to 60 Hertz. This would help for a while before the flickering would start again so I jumped back to 56 Hertz and I've been going back and forth doing this but this is just short term. What i'm really looking for is a permanent fix.

Thanks for your help everyone. Your suggestions would be greatly appreciated.
