Sabertooth Z77 not starting with new GPU

[James Wood]

I've started my newly built PC up before without a GPU as it came a little later. (I'm breadboarding ATM due to a faulty case).

It worked completely fine before. Now that I've inserted my GPU - a Palit GTX 670 2GB GDDR5, it won't start up.

Does anyone have any idea if there is some sort of incompatibility between these two components? Or if there's something I'm doing wrong. I have a 750W PSU, and it's all connected properly.

As I said, it still boots perfectly without the GPU inserted.

It bios issue with the asus mb and video card. Asus dropped a bios patch for it a long time ago. Use your USB flashback port and flash the newest bios to the mb.

James don't forget to turn on xmp profile for your ram or it may default to 1333 speeds.
