Switching power supplies can be very dangerous, so be careful when you
are working on the unit. Given the prices of decent supplies today, I
wouldn't waste your time troubleshooting or replacing caps - just
replace the supply. Several supply manufacturers, such as Antec, etc.
offer excellent supplies for a very low cost. Go to www.newegg.com, or
other good online sources, and find you best price on a 300 to 400 watt
supply.
