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.
