Namco System ES3 problems

[MostVerticalPrimate]

Hello all, the OKC Round 1 has been having issues with the Tekken 7 cab. Initially it was having slowdown on certain stages, but now it's not booting at all. It throws up this error message when trying to boot. Any ideas as to what the cause might be and how to fix it? Does the GPU need reseating, or thermal paste need to be reapplied?

This could be a bad update but it's mostly a broken GTX760.
I got bunch of memory error, directx error, and other strange stuff related to broken Geforce.
