Hopefully I am in the right place and apologies if not as I am a newbie to any kind of forum posting. I have researched my problem here and found similar situations but nothing that quite fits or has helped. Here is all the information that I have and the events that have led up to the black screen problem.
Lenovo S510p Touch Laptop running Windows 8.1 which was installed already on computer.
A few weeks ago I upgraded to Windows 10 however it caused some issues with emails, power options, etc. that I didn't have time to figure out so after about 1 week I decided to go back to Windows 8.1 thinking I would wait a few months and try again.
Everything seemed to be running fine at that point except that my laptop would still not "wake up" when opening top. I did install updates to drivers and Windows critical updates after moving back to 8.1 with no obvious issues. Until...I received an email that my Outlook emails would not work properly in Windows Live in a couple weeks unless I installed a certain update, so of course I installed the update. After that every email I received was from an "Unknown Sender" even after I allowed them. Because I couldn't find an easy fix for this I decided to restore my computer back to before this update was installed and that's where everything went wonky.
After initializing the system restore, the computer said it was working and it may take awhile. I got busy and after a couple hours looked at the computer and it was just a black screen. Pushing any keys did not change a thing so I forced a shut down. Upon restart, the Lenovo name appears with the circle of spinning dots then nothing. I can move the cursor and see it along with a small twirling blue circle but clicking anywhere on the screen does nothing.
I have tried unplugging the computer, removing battery, removing media in cd holder, pressing Shift on restart, F8, shift and F8, FN and F8, along with F11. I have forced shut down at least 30 times hoping that a system recovery or something would pop up and CTRL ALT DEL does absolutely nothing.
I should also mention that I do not have any type of recovery or installation disk but I did back up my files on external hard drive before installing Windows 10 so I'm not too concerned about losing files.
Any help is greatly appreciated as I am at a complete loss. Please note that I am not too computer savvy but can follow directions as long as you use "dummy" language and not technical computer terms.
