PowerPoint error message: No Disk

Hi folks and friends,
I meet an error every time I load Microsoft PowerPoint. The error message goes Windows – No Disk. I pasted below some additional text of the error for better view of the scenario.
Windows – No Disk
Exception Processing Message 0xc0000013 Parameters 0x75BE023C
0x8343FCBC 0x75BE023C 0x75BE023C
I already checked my computer for some virus, but nothing was found. I also found out that, when I use Microsoft Word this error is also present. That is why I assumed this error is general to both applications.
I am wondering what disk this error is pointing out. I did not remove any storage medium in my computer.
Please help me get rid of this error message.
Thanks a lot.
