Blood Sacrifice
Back on the day when building PCs for myself or for $company
I found that the razor sharp, nay these things put cut throat razors to shame
would exact a not insignificant amount of blood as payment; these machines would always work fine. On the odd occasion where tired from the blood loss and looking like I'd lost a fight with a possessed helicopter made of razor wire, those machines would always have issues until the appropriate blood sacrifice was made.
The old gods always require payment and will not be satisfied until the bill is settled
