I am hoping someone can tell me whether or not I should have these caps replaced, I have been having random shutdown issues on my pc and after alot of tests I have kind of narrowed it down. These caps were the only ones that looked like they might be going bad, but keep in mind they look worse in the pic here. But for a cap to be good does it need to be completely flat on top or overtime do they always swell a bit? Also Im not sure the brand, I can see TK on the sides of some or ATWY not sure if that helps....
