Nothing working on windows 7??

[IGoogleEverything]

Hello, I own a Lenovo G570 running windows 7 and recently my computer shut down to install some updates. After it finished with the updates I set my computer to sleep and when I opened it back up, the computer was stuck on a back screen with a blinking underscore on the left corner. After hours of googling, I finally figured out how to fix it. However, when I logged on to it and everything, the computer was stuck on a black screen with my mouse cursor in the middle.

I was fortunate enough to access task manager and run explorer.exe but I am not able to open anything. If I try, it'll give me an error saying, "explorer.exe no such interface supported" and such.

Any help or suggestions will be greatly appreciated, thank you.

try restoring to last known good config or just a point in time before the update
