That's the problem.
I don't have a serial number on a back panel (it's erased and in the bios too), just found this:
Nachine type10110
Configuration number 57310941
MO: CS02120315
CPU I3-3220
HDD SATA 1Tb
RAM 8G DDR3
GPU Intel
And on MB found that numbers:
3000025600584
10E2
4619KA38L02
B888E39B6456​
MB: VBA00 LA-9301P REV:1.0
EEPROMS: Winbond W25Q32BVSSIG and W25Q80BVSSIG...

Thanks for help, but I'm afraid this too complicated for me....
