"incorrect number of threads records" in verbose mode, reinstalling, reformatting impossible

after the install of an update of civilisation 5, a few hours later my iMacsuddenly switched for a millisecond to a blue screen, and went black.Since than the iMac i7 27' under yosemite freezes when the restarting bar under the apple is half full.It took me a while to be able to come to the disk utility.A reinstall is apparently not possible (HD protected-message), also formatting doesn't work.

option-D diagnostic online by apple didn't find any hardware problem.Only after starting up with command-V the machine admitted (after the order "reboot") an



"incorrect number of threads records

(4,1962333)"

than searched to repair the HD again and stays in this cycle.

I have no clue what that means.Is it a hardware problem, though apple diagnostic didn't find anything?Is it only the software or do I need a new computer?

The startup drive is failing, or there is some other internal hardware fault.

Back up all data on the drive immediately if you don't already have a current backup. There are ways to back up a computer that isn't fully functional—ask if you need guidance.

Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

Apple also recommends that you deauthorize a device in the iTunes Store before having it serviced.

*An SSD doesn't need to be zeroed.
