Windows 10: Can't Boot PC Stop Code 00021a

I shut down my PC as I had to leave, and when I turned it back on I get constant BSODs with the 0000021a stop code.My PC will boot with Driver Signature Enforcement disabled, but at this point, I'm not too sure what to do next. Because it will boot with Driver Signature Enforcement off, I think it's a driver issue but I just need further help.

BSOD - Inaccessible Boot Device

The reset save files equivalent if successful should be the quickest method to get you backup and running.

The backup files then clean install is the best option as you fix many problems and start fresh.

The command prompt commands are all trial and error.

Post code 99 at boot; help

This morning, to no avail, I tried a new power supply.

At this point I have tried all of the following:

• Disconnecting HHD (SATA and POWER)
• Disconnecting Opitical Drive (SATA and POWER)
• DISCONNECTING ALL F-PANEL (PWR SW, PWR LED, HDD LED, RESET SW)
• Disconnecting the USB and HD AUDIO
• Disconnecting ALL fans.
• Mounting and remounting the motherboard
• Mounting and remounting the CPU
• Attempting to use a new video card
• Attempting to use a new power supply
• Placing MOBO on a different surface
• Reseting the CMOS via the on board button and removing the battery
• Using only 1 stick of ram to boot
• New PSU

Basically I am booting the PC with the power button on the MOBO and the only things connected are the 8 pin MOBO power, the CPU, 1 stick of ram, and 2 different working video cards.

After doing all of those things, the MOBO stills post code "99" on the screen and on the MOBO itself. Additionally, keyboard does not work. Furthermore, I cannot access my BIOS or boot screen.

The original video card and the replacement video card both work on another PC therefore they are not the problem.

Thus, at this point, I have narrowed the malfunction down to either the following two components:

• Motherboard
• CPU (which I doubt, but do not have a AM3+ mobo on hand)

Any suggestions or advice are more than welcome and needed.

I am considering RMAing the motherboard... This process will most likely be 2 weeks and they may send it back saying it works it is my CPU... *Bang Head :banghead:
