Hi @xxghostbusterxx
In my previous experience, a WSOD (white screen of death) in Emulation Station is caused by too low a GPU Memory. You didn't specify which guide you followed, is there a chance that you changed this when trying to overclock the pi?
If you exit to the prompt by pressing F4 (even in a WSOD) and run:
sudo nano /boot/config.txt
modify the gpu_mem line to:
gpu_mem= 256
Then press Ctrl+X, Y (to save the file)
then type:
sudo shutdown -r -t 0 now
This should reboot the pie. If you still get a White Screen of Death, try changing to a different theme in emulationstation (press start on the controller, the menu will still appear).
