PC Build Problem P9X79 PRO
Posted on 2012-04-06
problem with a new PC Build:
Motherboard P9X79 PRO
Case: corsair 400R
Disk: intel SSD 500 series 120GB
CPU: Intel i7 3820 3.6Ghz
VGA: asus GTX 560 PCIe
RAM: 4XDDR3 1600 G.Skill F3-12800CL10D8GB PSU - 650W ANTEC
PSU: ANTEC Truepower 650W
When I power on, some times it posts, sometimes it doesnt (7/10 times it won't post). when it does, i verify that it can see all RAM, and the correct CPU and Disk.
when it doesn't post, the QCode lights on the mother board show AF (EXIT BOOT Services Event)
I have upgraded the BIOS to Version 0802, I'm unable to upgrade to the latest version.
I have changed the video card PCIe port, same results.. the RAM isn't on the compatible list in the manual, but when it posts,
I have rebuilt everything on outside the chasi to make sure it wasn't short circuit.. same issue.
when i try to boot windows from a USB, it loads the files but once it gets the windows screen, the qcode returns AA and everything freezes...
also, the "boot_device_led" remains constantly red for a long time after it posts..
