I had a cap on a relatives PC go out. It was not under warranty anymore. We stopped by rat shack (radio shack) and they had what we needed. Soldered it on and was up and working same day it died.
Funny thing his video died a few months later. It had a bad cap on it too!!! First time I saw a video card with a bad cap. We put a new cap on that and it is still running after 4 years. (PC needs replacement though, but all he does is ebay)
