Right-click on My Computer and select Manage. About half way down the list should be Disk Management. Click on this, and see if your drive appears in the right-hand pane. It may have been allocated a drive letter already in use. If so, right-click on the drive and select Change Drive Letter.

Try updating your chipset drivers. You should find them at your motherboatd manufacturers site.

You are just updating drivers - the same thing as updating video drivers. It should not affect your machine in any adverse way. Worst case, you can roll the update back using RollBack driver or System Restore.
