Picked up from where? Radio Shack? You need to use low ESR caps rated for 105 degrees Celsius/centigrade. Most, and likely all of what you'd find at Radio Shack won't be low ESR and will only be rated for 85 degrees. The uF needs to be the same. To replace a 10V cap, you could go with 16V, maybe 25, 35's kind of pushing it. When not operated near the rated voltage the oxide layer that works as an insulator between the conductive surfaces doesn't get and remain fully and properly formed, or something like that (been a long time since 'tronics class) And of course you have to observe proper polarity when you replace. You may have another cap that went, or is going, bad, that isn't showing visual signs, so checking the +5V and +12V outputs with a voltmeter is recommended.
