reverb sound from my speakers!????

I recently bought a MUSICXPC computer which came with Acronis Installed on it. This computer has been optimized for producing music. I accidentally downloaded a newer version of Windows Media Player on to my computer and all of a sudden any sounds or music coming from my computer sound like its coming from a cave. It sounds like a reveerb effect(echoey, cave sounding) no matter what speakers/headphones I use. No matter which music program I use to play the sound or music.
Has this ever happened to anyone?
I dont know if its Acronis or my computer or what.
HELP!

 

try checking the control panel for ur sound card (or chipset). sometimes it will have setting to change the "environment" settings or effects.

alos check any equalizer settings for in your media players.
