Computer won't boot after BIOS updated, please Help!

[giftedPenguin]

I was attempting to install Windows 8.1 as a virtual machine on Virtualbox.

System specs:

AMD FX-6300
ASRock 970 Extreme3 R2.0
MSI R9 270X
Win 7 64bit

Virtualbox would not allow me to make the machine 64bit. This is usually caused by a setting such as hardware virtualization not being enabled in th BIOS.

I went hunting for these settings, and could not find anything, but did find that my BIOS was out of date.

So i used the built in Flash Utility that downloads the latest BIOS and installs it.

Now my computer won't boot.

It begins booting, and I have a backlit keyboard, and the lights turn off as soon as the Windows splash screen appears. The screen almost does its splash and then i get a BSOD for half a second and it restarts.

I have tried Startup Repair.

I have tried bootrec/fixmbr

I also tried downgrading the BIOS to what I believe was the previous version.

If the SSD (primary drive) is set to IDE mode, the computer boots to a black screen with a flashing hyphen.

If it is in AHCI mode, it boots to the above symptoms (BSOD, restart)

I have reset the BIOS settings to default, Fast Boot is off, XBoost is off.

Any help will be appreciated, I can wipe the SSD if needed but I would prefer not too.

Clear the CMOS, there is jumper, or a button located on the motherboard, look at the motherboard's manual to be specific.

Attempted that, switched the jumper over, switched it back, powered on the machine. Initially it booted to that black screen. So I went back to the bios and changed the Sata Mode to AHCI

That allowed me to begin booting and then it BSOD again.

Quite frustrating, I can't go into advanced boot options or safe mode or anything. Any other ideas?
