Need Help with Clockwork Mod Recovery and my CM11 G2.

[Symbianblack]

Hey I want to know the exact steps to COMPLETELY wipe my G2 in Clockwork Recovery WITH OUT deleting the new ROM and GAPPS. I've been having horrendous sound search errors and now out of no where the system glitched and a lot of my options are missing. I'm on cyanogenmod CM 11 using 6/13 nightly.
