My gigabyte z77x-ud3h motherboard is hanging on the motherboard's splash screen. The debug LEDs are showing the code A3 which is 'activated all currently connected IDE devices'. There is a line a cross the top of the splash screen that doesn't look normal, there is pink pixels through it.

I cannot get into the bios settings at all, it freezes as soon as the screen comes up.

Before it broke I was cloning a hard drive with acronis true image. I had one ssd running Windows with 2 other hard drives plugged in that I was cloning from/to (one using SATA, one using usb). When it was done I turned off my computer, unplugged them both and put in my other hard drive with games on it And after that it would not boot.

I have tried unplugging all hard drives and everything plugged into usb ports. I tried resetting the CMOS using the button on the board and by pulling out the battery while the power is off for an hour. I unplugged my graphics card. However, nothing changed.

Any help would be great thanks.
 
No, I have tried unplugging all hard drives and everything plugged into usb ports. I tried resetting the CMOS using the button on the board and by pulling out the battery while the power is off for an hour. I unplugged my graphics card. However, I still cannot access the bios.
 


Its to the left of the front panel headers. It says it in the manual somewhere if you have it.
