Xbox One X Crashing to Dashboard

Hiya All,

Im hoping anyone can help me out as I am out of ideas what to do with the box of junk which is on my desk at the moment.

Its a One X 1 Tb Model 1787 which i have bought via Marketplace (seller claimed everything ok...) which in various games keeps crashing to the Xbox Dashboard.

This happens somewhere between 10 or 15 minutes ingame

What have I tried?

Replacing Harddisk, tried 2 different drives.

Replacing Sata Cable

Replacing PSU

Re-Applying thermal paste

Multiple Hard en Soft resets of the console

But none of this seems to fix the issue…

While replacing the disk i used the latest OSU1 downloaded from Microsoft.

These problems were also present on older updates.

Is there anyone who can point me in the right direction to get this resolved?

Thanks a lot!
