Fix Partition Names

Something changed all my partitions names to local disk.All the drive letters are ok and in disk management all the right names are there.If I try to rename a partition it does not change and stays local disk.What would cause the partition names to change when I open computer,but disk management all the names are there.How can I make them go back to the names I chose instead of local disk.Anyone have any ideas.I also checked in safe mode and after opening the computer icon all the disk names are there like they should be,just in windows it showes local disk.Update..I installed a new windows 7 this morn and even on a fresh install all my named partitions showes as Local Disk but in disk management all the names are correct the way I had them.
