so my screen has had some wierd issues in the past. sometimes when i close it the screen is a bit unreadable. there are vertical lines all over it that makes seeing anything impossible, if you closed it and opened it the screen would either be normal or it would be lines again. this was like this for months. well just now when i turned it on it took many many more attempts than usual to get a stable screen. i had spilled some whiskey on the pc months ago but cleaned it up and the screen issue had been happening before that. im a bit afraid to turn my screen off now. now the background sometimes appears burned into the screen when i change tabs. what do I do?
