ok, i give.
this desktop unit was given to me, there is no motherboard box.
I respectfully request to disengage from the problem of the 2nd, damaged HDD, I have another issue that I feel is more upsetting...i've found a windows program that I downloaded to linux and don't know what to do with it now...it's an exe. and if i was anywhere but linux, i could handle it, here is what i see on dolphin: 7zip_installer_d793026.exe
it's supposed to be a version of windows 7 that I can install ...but i can't...
