my xoom keeps making this screeching sound when im playing, i tried setting my kernal back to stock to end my overclock,to see if thats what was doing it, but it still does it. any ideas?

Hm, I have no idea why it would do that. Does the device's volume control affect it? Try going into Options->Audio and change the volume of either the sound effects or the music to see if one of those affects the noise, and then mute both to see if that helps.

nope,even on mute it does it, I have found the culprit I think. Every time I exit vendetta,before i replay, i have to clear the chache or it acts funny
