I had a formula DVIII Maximus motherboard under warranty. It failed post within three weeks of owning it. I sent it in they sent it back saying it passed all tests. I then had to purchase all the components to troubleshoot; CPU, PSU, RAM and sent to professional shop since all components resulted in same issue. They concluded it still was motherboard. I called and explained this to ASUS and they said they didn't have a board to replace it, couldn't tell me when one might be available. Frustrated with the month long ordeal and unknown availability ( from the company that manufactures it)
I bought another board, same type. And, it fixed the non-POST issue. If ASUS had tested it correctly, I would have been back up within a week. No apologies from ASUS. Very expensive ordeal for me. Crap customer service for a 300 billion dollar company.
