So today I decided to overclock my CPU. I followed a video tutorial step by step for my ASRock Z77 Extreme4-m. After completing every step in his video, I selected save changes and restart.
Now the computer will not boot up. If I turn it on and touch nothing, it stays at the Motherboard screen (where it says F2 or Delete for BIOS, etc.) but when I click on F2, F11, or anything nothing changes.
If I spam F2 while the computer is starting up it goes to a black screen with only 2 characters at the bottom right (B4, A9, etc.)
I am extremely worried that I screwed something up. Is it possible to fix this? I just built the computer myself a few days ago. How do I know what went wrong?
