I have a Dell Inspiron 7500 laptop for about a year and 4 months now, It never really gave me an issue but now suddenly it has started exhibiting an issue.
The screen turns to dark bluish(Not black but almost near to that shade) suddenly and then remains there, It doesn't shut off even on closing the lid, the only retort is to shut down and start over again.
I thought there could be a virus, So I reset the Laptop still the problem persists.
I am not sure about overheating issue, But it may exist,as I do observe laptop heating up at times.
Note: My laptop battery is in poor condition so it's always on AC supply, Something interesting to observe is that, Every time this issue has been caused, I was on youtube , watching a video full screen, I cannot say this only occurs on youtube but that's my observation.
