I have never seen anything like this, can anyone help? I think its the screen but who knows, anyone experimented something like this?

Also when I leave the computer alone the dots tend to disappear a bit or change throughout but they wont just go away, it gets better or worse but do not disappear at all.

The computer also does not respond, when I move the mouse it does not do anything until a couple of seconds later it shows the mouse at another location, same with the keyboard it does not respond until later, but I dont see movement or the actual typing.

Sorry if I uploaded the images so big I have no idea how to do it correctly. And I also tried to connect a vga cable to other monitor that I have but does not show up anything it acts like nothing is connected to it.

I want to know if anyone had a similar problem and what their problem was and how they fixed it because I have no idea what this is.

Thanks

It makes me think of a loose cable, but try the following steps to test it...

1. Turn the laptop off (not sleep or hibernate but off).
2. Connect an external monitor to the laptop.
3. Turn on the external monitor.
4. Turn on the laptop.

NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.

If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.

If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.
