my computer is about 3 years old now :S. it was pretty decent when i first bought it, but as of recently it seems to be acting up a bit. i've always played a game called 'warcraft 3' fine on my computer. i've never had a problem with it before, but as of lately, when demanding situations happen. ie, playing on big maps with a large number of people. or playing specific games that have a large amount of units attacking each other, my computer starts to get choppy. occasionally its terrible. i've also noticed that some flashgames that i've played on the internet have started to slow down when demanding scenes come up.
would this be a videocard problem..? could it possibly be RAM (i want to replace my RAM anyways, so this would be the better of the two). could there be some other problem? if it was one of the first two, would there be some sort of test or something that i could confirm it with, hopefully one that doesn't require me to sub out my videocard/ram with working videocard/ram.
i look forward to your answers
