Well, for some reason, I just can't play games because the screen just changes when I play games like: Ragnarok Online, Exteel, Avalon Heroes, C&C Generals... Etc. (Sorry, I really need to mention these games because I can't properly play for some reason)
What I mean with changing, the screen goes black randomly and it suddenly changes to a different image, like a distorted screen, but the distortion is a colored noise-like image and hangs.
But I don't know if that problem is in my Graphics Card installed or just the RAM or the Video Card existing in my CPU or just the Monitor (It's Samsung Wide Screen)
When I play Flash-based games or Flash sites, it's just normal, nothing happens.
When I screenshot with the description I said, it just look NORMAL.
Graphics Card: NVIDIA GeForce FX 5500 series (But I have also a problem here, I installed GeForce 6200 series, but FX 5500 shown in my screen resolution change)
Me and my brother tried everything we could do, but we don't know what is the main problem.
