Default [Q] Random Memory Card Disassociation

Something odd started happening with my Sch R950. After, but not immediately after, I installed android 4.3 my phone seems to disassociate with my 32 gb memory card. When I try to access the directory through "My Files" there is a long lag whenever I switch between device and card storage. When I try to install bigger games (e.g. hungry shark evolution) I get a message saying "cannot write to card" other than games my ringtones will revert to stock, my music will take forever (sometimes it won't) come up. It doesn't seem to be everything on my memory just somethings. My device is rooted no custom recovery, no custom roms. I have deleted a few stock apps but non that I think would affect my device operation.
