or like heat grease?

was cleaning it out yesterday and noticed little black solid stuff on top of most of my capacitors?

pc runs as slow as it ever did

runs quieter now

 

just a question on weather this thing might die soon

dont know the model

this was assembled and given to me buy a relative

parts all should be over 10 years old

The short answer to your first question is 'Yes !'. These capacitors are all on their way out and when they finally let go your mobo will stop working.

 

However, if your soldering skills are any good capacitors of this type - electrolytic capacitors - are not too difficult to replace as they are not surface mount. You would need to remove the mobo, source replacements - which should not be too difficult, remove the old ones by de-soldering carefully and solder new ones in place.

 

Sourcing replacements is made easier by the fact that electrolytic capacitors normally have the value printed on the case. There are two parts to this - the capacitance and the voltage. The capacitance is normally expressed as a number of uF (microfarads) and the voltage as V (volts). While the values are not normally too critical do not use a lower voltage rating than the one of the old one, but a slightly higher voltage rating would be OK. For example, if the old one was rated at 12V you could replace it with one rated at 16V but not with one rated at 5V. The other important aspect of electrolytic capacitors is that they are polarity sensitive. One terminal is always clearly marked either +ve or -ve and they must always be connected with the correct polarity. If it is to be used on a +12V rail, for example, the +ve terminal must always go to the +12V side and -ve terminal always go to the ground (0V) side. If you get this wrong their service life can be measured in milliseconds once you re-connect the power !

 

While it is your decision, as I said replacing these is not too difficult, it may be time to bite the bullet and replace the computer.

Continue using till it quits, all the while planning your next system purchase/assembly....

When you stop and think about these capacitors you may realize that the motherboard isn't the only component which uses these.  A PSU use much larger capacitors than those found on a motherboard and experience the same type of degradation.  At ten years of age I would be backing up every important file on the hdd and be planning to purchase or build another computer in the near future.  Ten years?!?  You've gotten your money's worth out of that and then some.  If all you use this computer for is email and online browsing you could still be satisfied with this computer.  But the technological leaps in components alone is incredible, but coupled with the software advances as well this computer is a dinosaur.


Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

The clue to the failures or reduced function is the oozing of dielectric paste  from the bottom, unto the surrounding board.  Evidence of failure is if the top begins to bulge.  The black material is the insulator inside the can.  Loud popping noises usually comes with the catastrophic failures and will spray the paste all over everything.  Some manufacturers us a dab of silicone between the cap and board to hold them in place during assembly.
