Hi, I've just upgraded from a 7+ year old machine, so I may be a little rusty when it comes to trying to problem solve the following...
When I'm in game (Alien Isolation, occasionally GTA V, so far not X-COM), I'm seeing the occasional system freeze. I have to do a hard reset to clear the error, windows boots OK and it's like nothing has went wrong. Checking the event log, I'm seeing the following error, which I think is related (it is the last error I can find before the "system lost power" one, from the restart): Driver ACPI returned invalid ID for a child device (5). After a bit of googleing, I'm still not 100% sure what this is.
