plus the sound doesn't even work. I have installed all the drivers

Try this...

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.

You may also want to try hitting CTRL + SHIFT + WIN + B to try and reset your graphics driver as another possible fix.

I have tried to use an external monitor but it shows the same mess and closes. I haven't tried resetting my graphics,I will update you on that

I tried pressing Ctrl+shtift+win+b but nothing happens

And did you try the other instructions?

And did you try the other instructions?

Yes, but the problem still occurs. I tried reinstalling the drivers hoping maybe a miracle would happen but no. Fortunately, the cpu can be replaced on this mobo but the problem is that it a mpga478mb and i didn't have any luck finding a cpu for that.

If it happens on both the device and the external monitor, then it is likely the GPU is the problem.

 

[djlamp94]

so then what should i do, replace the cpu/gpu?

You may have to replace the motherboard if it is the GPU.
