Hi,
I have recently applied Supee-9767 to my Magento 1.7.0.2 platform. We use a custom template so I added the formkey code to each required element.
<?php echo $this->getBlockHtml('formkey') ?>
All works great and as it should except for the payment.phtml side of the checkout. You select your pyament method, hit continue and nothing happens. I have disabled all methods one at a time and still the same, so it's not the methods.....

You should uninstall SUPEE-9767 and use SUPEE-9767 v2.
Do you have form key validation enabled on the checkout steps under Magento admin
System > Configuration > Admin > Security > Enable Form Key Validation On Checkout
You should add for key to any custom payment.phtml also check if you have app/code/core/Mage/Checkout/controllers/OnepageController.php overridden in any custom module. If yes, than you need to make changes in the file as per patch file.
