it could be because it has dead ram in it, you should check if all ram is working
if used wet tp with water to clean screens (though you should use microfiber towels lol)its fine. but if you spray something onto the screen you risk forgetin it up if it drips down.
it actually hasnt happened since i made this topic so it's kinda weird.
sounds like an issue with your backlighting, check your power settings for any wonkiness
it is pretty old. how would i check that?
you can check if your ram is ok by taking it to a professional, like computer fixers or computer part stores, as laptops are hard to do so without loving up. i suggest not trying it yourself.
try doing a ram testuse windows memory diagnostic tool, as explained here
