They're probably 3300uF (microFarad) and rated at 10 Volts, and are in parallel across the +5V output. Go read the thread loubob57 linked to, and any threads linked to in that thread. Somewhere you should come across what I say about Low ESR, high temp, and don't look for them at Radio Shack. Are you anywhere near Raleigh, NC? I gotta guy up there sells 'em. If you replace both of them and the ones on the +12 V output as well, that's maybe $10 in parts total, not counting shipping if you mail order. As un-soldering and resoldering jobs go, it's fairly simple, but you'll need a heavy enough wattage iron or gun to overcome the heat dissipating properties of the big areas of copper on the bottom of the board to which the capacitors leads are soldered. In addition to the obvious screws (for which you'll need the same #10 Torx bit you need to open the case) on the inside of the chassis holding the power supply board down, there's a small dark screw that goes into the plasic of the AC input socket from the outside, just above the actual pins, and you'll need a slightly smaller Torx bit for it, maybe a #8 or #9.
