If your PS has trouble starting because of faulty caps, it's probably
not because they are draining---on the contrary, they are probably worn
out and leaky (electrically), causing trouble for the startup circuit
which wasn't designed for the extra losses. Often you can identify the
failing electrical capacitors because their casing is swollen or maybe
even burst open and leaking the actual electrolyte.
You'd have to disassemble the power supply to see that, however, and
there are possibly dangerous voltages inside even for some time after
disconnecting the power, so I don't recommend doing that.
The bottom line is that the power supply is probably on the fritz and
likely to fail altogether. Decent power supplies aren't that expensive,
I recently got a nice, quiet one for around $30-40.
