Question Random letters/numbers in system information from a PC bought of a marketplace

[kelvinchilli]

I recently bought a PC from a marketplace and I saw in system information were random numbers/letters in the baseboard name etc. How can I fix it? (Can I still upgrade CPU without any problems when its stuck with those letters/numbers?)

a system from unknown seller. do a fresh os install
about upgrading cpu, full system spec?

I think it's just a prebuilt from NZXT. The player two specs probably. I got it for 1000$

That's no information we can't go off of I thinks.

First thing to do is wipe all drives and do a fresh install of windows.
I would never trust anybody on the marketplace.
