NEW crashed primary site - datediff-function overflow

[mecmnub]

Hi guys,

i hope somebody can help or just say, that i can build up a new server.
In october last year suddenly i cant access the sccm management console. I figured out, that the database CM_... was flagged as suspicious. At this moment i don't have much time to do much research and of course there are no backups, so i just did some repair attempts wich doesn't work.
Now i have actual a bit more time. The errorlogfiles of the sql-server filled up the drive. I tried to rapair and it worked! (DBCC CHECKDB)
I can access the management console and see my softwarepackages and computers, but no collections or provisionings. Every time when i click on "Assets and Compliants" i get the following error message:

ConfigMgr-Fehlerobjekt:
