Windows 10: Laptop Black Screen after Win 10 update

I updated from win 7 to win 10 three years ago. All was well until March of this year, when the laptop sometimes failed to complete boot cycle and gave a black screen. The problem got worse and worse and I resorted to resetting the laptop and reinstalling Win 10,but now the laptop is unusable -- just get a black screen each time I try to boot. The device simply won't complete the boot cycle. I have tried every solution I can find to fix this problem I already shut off Win 10 updates but nothing works. Is the only solution to completely wipe the drive and install windows 7?

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

 

Black Screen During Driver Update

I reinstalled my laptop back to factory settings, and I wanted to update the GPU drivers. But when I try, the screen turns black during the update, but the computer is still running. I was forced to turn off the computer and turn it back on. I used system restore, so now I'm using the default drivers that came with the laptop. Can you guys suggest anything?

 

BLACK SCREEN ON STARTUP AFTER WIN 10 UPDATE

Thank you for the prompt reply. BTW its a Toshiba L500D. Yes I've tried forced shutdown repeatedly. I've tried a remote monitor (it gets "put to sleep, too"), I made an Installation Media DVD on another Laptop and tried that to no avail. I've tried Control-Shift
Esc; Ctrl-Alt-Del; F1, F2, F12. I've connected a known good HDD to a USB port. I've removed the HDD and substituted a known good HDD. I removed and re-fitted the RAM chips as suggested by Microsoft. All the while doing hard resets. Nothing gets any response
from the Black Screen condition. I cannot apply any of the fixes suggested such as I've been able to find in hours of searching because I cannot get anything but Black Screen. the Power light is on, the HDD runs up, the DVD drive runs up and just Black screen.
