Screen Flickering

So I finally got my computer to work but I'm still left with one tiny problem. The screen flickers on dark colors like black, dark blue, dark brown, etc... My friend had a similar problem, and it was caused by a bad dvi to vga adapter. I'm also using an adapter, but I'm not sure if it is causing the problem... Can you help me?
 
Try a different cable or adapter. If you can it would be good to try another monitor if you can find one laying around.
 
The weird thing about the whole thing is that I noticed that the screen doesn't seem to flicker in ubuntu but it does in windows XP...:confused:
 
I checked the refresh rate. and what now? Also, I didn't make any driver updates... I think it's caused by a bad vga cable cause when I plug in my old 8400gs the same thing happens.
 
I fixed the problem by using an HDMI cable instead of a vga cable... weird the monitor was flickering with and w/o an adapter plugged in, it was flickering on both my gts250 and 8400gs, and using an HDMI cable instead of a vga cable fixed the problem. I know that the vga cable was working fine cause the monitor wasn't flickering when I used it with my laptop... maybe windows XP caused it somehow... anyways the case remains a mystery until someone finds a good explanation :confused:
 
VGA is an analog signal. DVI and HDMI are digital. I don't really know how that would affect it unless you just had a bad cable or a bad VGA input on the monitor.
 
Still doesn't answer why the screen was flickering on the vga cable because the cable worked when used with a laptop... it just didn't work with my desktop :confused:
 
logic would suggest a bad vga port on monitor. Research the half-split method.

I will make myself clear, my laptop works perfectly normal on the same vga cable and on the same monitor, so I don't think that it has a bad vga port...
 
Nothing you have done has excluded an intermittent fault in the monitor vga port. That and the cable are the only common elements. Its the vga port on the monitor in all probability, probably mechanical wear.
