Was a working system for 4 years never had a problem, let computer on over night and when I went to use it I had a black screen so I rebooted it, then from there it would not post, I have tried every component except cpu in another PC all working. I got multiple qcode 90, 98, d6 and a few other I cant think of at the moment , I was just going to repair the mobo but it's out of warranty so I bought a new broad and still getting the same codes, I flashed bios 1 with latest version. Bios 2 is wht the board came with so no clue what version it is.
