Video TDR failure (kind of)

[Soldierdude1234]

Hey, this is going to sound really weird but I've been trying to fix my cousins pc, at his house when it's plugged in every minute or so it will crash and get video tdr failure. The only thing that stops it in his house is if it's booted in safe mode of Uninstaller the drivers, I also used a different graphics card and it did the same thing. So I took it home to continue troubleshooting, as soon as I plugged it into my house nothing was wrong I played on it for hours, so I pinned it down to a faulty cable. This was not the case tried all new cables and no hope at his house, we tried different outlets and circuits too but all the same result, so I took it home and still absolutely no issue, so I took it to my friends house and it got the tdr failure I'm honestly stumped and wondering why the pc only likes working in my house.  Please help me
