Root Preparing sd card notification then home screen loops till crash

[CTroxtell]

My fiance got a Ally and I put Velocity .4 on it just like mine. After installing apps on it it'll just randomly sound the notification and will say Preparing SD Card and the home screen goes into a loop then crashing and having to have the battery pulled cause after it crashes and reboots and just boot loops. Has anyone had this issue? Was also wondering if it could possibly be something with the sd card.

Here's the debugging I would try, in increasing levels of desperation. I'd start with the first, then work your way down each time it fails. Keep in mind that the first is the only "non-destructive" one.

o wipe /cache and clear the dalvik-cache
o wipe /data (and /cache) (this will erase user apps)
o reflash your rom (and re-wipe /cache and /data)
o flash a different rom (and re-wipe /cache and /data)
