Stuck on efi shell

[s4nuj]

Hello,

I recently did a computer build which started up all fine and manage to install windows 8.1. I recently decided to activate the windows 8 features in the bios menu and now every time the computer starts it is stuck in the 'efi shell' and no devices are mapped to it. Keyboard is unresponsive and switching the hard-drives to a different sata ports has not work.

MB: MSI 970A-G43 AMD 970 (No internal graphics) How would reset the CMOS safely as MSI do not provide a Jumper?
GPU: MSI GTX 750 2GB GDDR5
CPU: AMD FX-6300 3.5GHz Socket AM3+

If anybody has any ideas to solve this, be much appreciated?


Thanks

The clear bios jumper is on page 1-28 in the motherboards manual

Thanks Joe, I have located the two pins but do not understand what the black rectangles mean. Do i have to short it with a screwdriver?

Yes...turn off the pc and disconnect the power from the wall, use a small screw driver and short the pins together, then remove your screw driver and from there you should have the bios at the factory defaults

^ In addition to Joe's suggestion, after you unplug the PC, press the power button a few times to drain any residual power left in the PSU's capacitors.
