I think the episode name is The Computer Menace... Maybe. The one where Homer gets a computer, makes his own website and spouts a load of "grade a bullcrap".
I can't name the exact episode without googling, but it's after Maude died because I remember one of the boys being so delirious from the fever the cold raised in them that he thought he saw his mom... And the artstyle is relatively early. Has to be from the 90s...
