Acer Aspire Z 24 Green Lines/Tint Problem Help

Today my computer screen was acting weird. Like there was a a tint that I could see and it was starting to turn green from the top and bottom of my screen and I don’t know why. I tried shuttting my computer and uninstalling programs but it wouldn’t work. I tried to unplug my computer and wait for a while but when I need that I got the blue screen of death and got a critical process died error. Also I noticed that with the weird green tíntate the top right there is like a medium or large black dot I’m not sure what that means. I think the issue is me being crazy and having so many tabs open that it made my computer gpu or something died. I’m not sure if I can save my computer but any help is appreciated since I’m so confused on what to do right now.
