I do have XMP active and i have overclocked my CPU, managed to push it about 17% over frequency spec and about 10% over wattage spec.

Yes DOS commands are not always accurate.
Did you, perchance, have a USB stick in the system when these errors occurred?
 

Snaked this from MS's website
___
The command list disk will let you know the index number of the disk.
 
Follow these steps to format the drive using the Disk part command:
 
a. Click Start, type cmd in the Start Search box.
b. Right-click cmd in the Programs list, and then click Run as administrator. If you are prompted for an administrator password or confirmation, type your password or click Continue. 
c. An Administrator command prompt will open. Type in diskpart. Your command line will look like this:
     d. Then enter this command “list disk” without the quotes to display all active disks on your machine.
 
post a pic of what you see

Ok, we need to find out which disk the OS thinks is Disk 5.
Control Panel to  Admin Tools to Computer Management to Disk Management
Right click on each drive partition and choose "properties" go to hardware tab, highlight the drive and down below is "Location" which *should* give you drive numbers.
 
I AM WORKING FROM MEMORY HERE (at work with a system with only 1 drive) SO I MAY BE WRONG ABOUT THIS....GOOGLE WILL HAVE MORE ACCURATE INFO FOR YOU
 
Once we can find out which disk is "disk 5" we can go from there.
 

You may have one, if your drives are partitioned (and the C drive will typically have at least one partition) then each partition is seen as a drive.
Look in event viewer and then the subsection for Windows Logs and then the subsection for "System" and look for any Red X errors, especially associated with "disk"
 
If you find any, post a screenshot here

Will need full system specs please, also list what things are attached via USB.
