Vista was known for this performance. I just gifted an Acer 5570-2977 with similar specs and so I can commiserate that it's a dog. Fortunately we replaced it with a 250 buck laptop later and that laptop runs circles around that Vista laptop.

There was a few reasons to gift this to a student such as the student was a good one and their laptop was dead among we wanted to move it out of the office because engineers would waste hours trying to fix it.

It did run Linux much better than Vista so if you just need a web browser and media player, maybe it's time.
