Hacking a game has absolutely nothing to do with a motherboard frying/failing unless you try, saying overclocking (at most).
When devs use PC's for their games, that may be more of a good thing for you (since it may not be a proprietary piece of equipment which can be defunct, unlike other PCB types). Can you pull the specs from the game or request from (what's left of) Roxor as to what it is?
I'd say maybe check all your connections or see if you have a loose board connected in the box to see if maybe all the cards/connectors are secured, but I'm sure you've tried it already. |
