[SOLVED] POST only after CMOS clear (QCODE 95 - restart)

Hi all!

My PSU has recently died. I've gotten it replaced with a working one, but I'm now having trouble getting my system to boot correctly.

Here are the symptoms:

1. It POSTs, but only after a CMOS clear.
If I enter the UEFI and then restart in any way (even power cycle), the subsequent boots will restart after QCODEs 68-79-91-95-restart.
The restart isn't full (the fans don't turn off), the boot sequence simply goes back to the beginning (QCODE 00).
Here's a video of the QCODE display when it's restarting ad infinitum: http://v9.tinypic.com/player.swf?file=21kmasy&s=9

2. When it POSTs after CMOS (this happens 100% of the time btw), it spits out two error messages. (http://imgur.com/NhpM4gG)
* "CPU Fan Error!" - this is because my system is liquid cooled an I need to set the CPU Fan Monitor to Ignore. (http://imgur.com/a/q5135)
* "When RAID configuration was built, ensure to set SATA Cofiguration to RAID mode" - this is because I have a RAID controller and need to set PCH Storage Configuration to RAID. (http://imgur.com/a/OurCC)

Here's what I have tried:

1. CMOS clear, boot into UEFI, exit with no changes. Result: goes into restart loop.
2. CMOS clear, boot into UEFI, make changes to CPU Fan Monitor & RAID config, exit with save changes. Result: goes into restart loop.
3. CMOS clear, boot into UEFI, power cycle the PC. Result: goes into restart loop.
4. CMOS clear, POST - do *not* enter UEFI, power cycle the PC. Result: POSTs again with the same errors.
5. CMOS clear, boot into UEFI, boot directly into Windows Boot Manager (straight from UEFI, do not pass go, do not collect $200, do not restart). (http://imgur.com/a/Fq3mX) Result: Get to the windows loading screen. (http://imgur.com/a/Zl7gF) After a few minutes, it BSODs with "INACCESSIBLE_BOOT_DEVICE". (http://imgur.com/a/xk9Qe)
6. CMOS clear, boot into UEFI, run memtest off a USB. Result: memtest is 100% successful.
7. Disabling different PCIE lanes with the onboard switch, CMOS clear, boot into UEFI, make changes to CPU Fan Monitor & RAID config, exit with save changes. Result: goes into restart loop.
8. Switching to the secondary BIOS setting via onboard switch, repeating above steps. Result: no changes.
9. Accessed the SSDs in the system (including RAID drive) via EZFlash tool in UEFI (just to browse contents). Result: was able to browser contents of SSDs correctly.

Have you tried flashing latest BIOS or flashing fresh version of current BIOS? BIOS flashback method.

I'd also strip system of any usb devices you can...maybe even strip all non essential drives...maybe try single RAM sticks...basically minimum system

You could reseat CPU...check socket pins...

try and flash the bios.

Thank you! I will try this first.

Sorry, forgot to mention. I'm running it with just USB keyboard + USB mouse and one DVI-D display plugged in.

maybe even strip all non essential drives...

maybe try single RAM sticks...

Will try - thank you!

Solved! Thank you for your help!

As I was trying to remove parts from the system and run it barebones, I removed one of the GTX 980 TIs and the system POSTed correctly after reboot!
Guess my PSU took out one of my GPUs with it - funny that it was showing up fine under GPU Post in UEFI/Tools.
