I am truly sorry to hear your mobo stopped working! Please remember that you have the option to check your warranty options with our support over the phone, chat or email.
In terms of compatible boards, I can recommend the following link: http://intel.ly/2guuZkJ
There you can find both Intel and third party boards that are compatible with your Intel® Core™ i7-3770K Processor
Some things you can check while choosing a new motherboard:
-Form factor (size), depends on your case and requirements
Please remember that the best option for you is to get a board that has PCIe 3.0 available so you can get the best out of your PICe 3.0 GPU!!
If any additional inquiries come to mind in the future, feel free to contact us back
