Devlin, a Pentium D is a dual core.

nfsworldrace, you can get another Pentium D for $1 if you look.

Chances are if you hurt the cpu, you hurt the motherboard too

Here there is a great reference http://www.tomshardware.com/reviews/power-supply-specifications-atx-reference,3061-2.html
The meters can be bought for just a few dollars and come in very handy anyway.

Your CPU well I would suggest trying a CPU that will be compatible with the board but that is up to you really and they can be got for very little these days but you take the chance of course of getting a dud .
note - this psu voltage measurement won't work if the ATX 24 pin is pulled off the mobo for testing. In that situation, you have to short the green PS-ON to ground to soft switch the psu. I wouldn't recommend this procedure to the inexperienced (too easy to short the wrong pin).

Capacitors are usually layers of foil and paper with an electrolyte solution in them. There were manufacturing problems in the plant/s making them some years ago that cause the bulging and/or leakage but haven't seen the problem in computers of the last few years, maybe the supplies have finally been refreshed and the issue no longer exists. It could also happen in power supplies. I haven't had to junk a computer because of the problem in the couple of years. Replacing a motherboard may be less cost-effective than getting a new computer if a board that will accept your CPU and Memory may not be available.
