A couple picked up the system from my house today. its a i7 3930k box with gtx 560ti. they were intending to play games on it. We tested the system everything worked when they picked up.
Tonight they claimed after playing a game the system shut down and never wake up again. they have tried many means the box just does not light up their screen anymore.
I am not sure what to do. they seem genuine and who knows what went wrong during transport.. by their diagnostics I suspect the motherboard or cpu is now dead. The system is 6 years old and never had any issue before. they paid $700. I asked them to bring it back to have a look. but i know someone is going to lose $700 and most likely its me.
That threw I'm not responsible option out of the window
