I recently purchased a second-hand DX79TO motherboard (and i7-3820 processor) but I am missing an I/O shield. How would I go about receiving a replacement I/O shield for this motherboard? Thank you!
Please get in contact directly with Intel through chat, email, phone or online support, you just need to select boards on product type and you will get those options, they will be able to check if they have the I/O shield available for your board:
Any questions, please let me know.
