Here are the steps I followed...

- removed old caps using soldering iron and de-solder suction device.

- removed all old solder

- cleaned pads and remover residue using 98% isopropal alcohol.

- soldered on new caps.

- put board back in system to test. Heard system beep, system booted, played 2 sounds. All was well. Shutdown, removed board.

- washed board with warm water and small amount of dish soap with a soft Roth brush.

- dried board in a warm, dry area for 2 days.

- put board in system, boot with no beep. Tried to play sounds, none.
