Volume Label Disappears

hi everyone;
there was no problem until i was found that there is 7 x64 sp1 integrated version of MSDN.after i was install that version(by the way cd is orginal.)my drive volumes suddenly dissapears.i can see them at disk management bu not in my computer..i was tried few tweak problems, also option in the folder options which show or hide drive letters,try to rename it with f2 od rename option it renames but when i got enter turns backto untitled or local disk.searched hole over the net about 3 days but nothings to find only i found 2 problems as same as mine but they were unsolved too..i tried to install diffrent version of the windows (vista sp2 xpsp3)still the same.only strange thing is when i get in to safe mode windows is able to write volume labels in my computer..
pls if some knows it help me.gone crazy soon.
thnx from now on...
best regards...
