PC Workshop has seen all sorts of Mac problems over the last few years, but the one we tend to see quite often is listed today which in certain cases is the most worrying as it wont allow users to retrieve data!
A flashing folder with a question mark at startup time means that the machine cannot find a valid boot volume.
This doesn’t necessarily mean that the hardware is broken; it may just be that the contents of the internal drive has become corrupt or erased.
One way to restore it is to use the recovery partition, if its still viable if not then we can still probably recover your data.
If you have an external USB hard drive with a bootable copy of Mac OS X on it (e.g., a backup that you created with a cloning program), you might try booting from it.
