Apple Hardware Test with aftermarket GPU?

[Jayson A]

Is it possible to run the Apple Hardware Test without a boot screen? My Mac Pro has been acting weird lately. Random shutdowns, random restarts... there's no log information that actually tells me that anything is malfunctioning, so I'm assuming I have a hardware issue (power supply... ram...?) I don't know, but I'd love to figure it out.

Has anyone run Apple Hardware Test without a boot screen?

AHT will need Mac EFI GPU to view. Do you still have a stock video card on hand? What GPU are you running, is it drawing too much power (random shutdown)?

For what it's worth, AHT is pretty bad at testing things outside of ram, it might not be of much use to you.

Every time my computer has shut down randomly is when the gpu is not being stressed. Sometimes it shuts down when putting it to sleep and I had a random restart the other day when trying to enable FRTC in windows.

Check your NorthBridge temperature.
