Soundcard Latency - Delayed sound

Soundcard Latency - How do I get rid of the delayed sound coming from my computer?

OS: Windows XP/windows 7
Keyboard model: Yamaha PSR-175
MIDI connection: M-audio MIDI-USB Uno
Recording Software used: anvil, cakewalk

What I Want:
I just want to connect the keyboard to the computer and play. The sound should be generated by the MIDI virtual sound canvas through the PC speaker. In this way, I can play more instruments other than those in the keyboard.

How do I correct the delay of sound? There is a tendency for me to play very slow just for the computer to catch up the sound.
