Windows 10: My laptop screen freezes after a few moments, turns black and then glitches when I press...

Since yesterday, my screen has been freezing after using it for a while. Then the screen was just black when I try to boot it up after forcing it to shut down. I let it rest throughout the night and then tried again right now which now I was able to see the lenovo logo and then log in. It was working for a moment but then the screen froze and turned black. When I hit the keys in the keyboard, the image would return but it was glitched and was still frozen. I don't understand what is happening and I'm worried if I need to replace something or get a new laptop.

Toshiba Laptop Black Screen

I have a Toshiba Laptop, Was reinstalling windows 7 on it last night left it doing the updates then shut it down. Turned it on this this afternoon only to find the laptop screen is Black and also there is a burning smell coming from the Fan.

I connected the Laptop to a external monitor that is fine, Can go into bios, Windows boots up fine Etc.
Just took apart the laptop earlier to check all the cables where in correctly, Checked the motherboard over for any damage, burnt bits but but found nothing. Just put it back together now but im still getting this burning smell and i still cant use the laptop screen only a external screen.

I Tried Pressing FN+F5 to switch to the laptop screen, But still black screen. Any Suggestions please ?

Thanks

 

Freezing screen and glitches

As I boot up my laptop it boots perfectly but after I login for more than 5 seconds later the screen freezes or glitching or maybe goes black screen sometimes. If I try to troubleshoot then green dots appears and screen freeze. I can not do anything

 

screen turns on and is black before going to the Login screen

When turning on my laptop the screen turns on and is black (as it normally is) before going to the log in screen. But during the moment it's black there's a random screen glitch, mostly contained at the bottom of the screen. It does seem to affect anything
during use but I'm concerned it might be something else in the back ground that might be wrong or it might conflict with something later.

I don't have any other issues with the screen other then the odd time I exit full screen with Edge and the display driver crashes. That was a problem long before the pre-log in glitch though.
