Computer won't boot after you overclock

[kamijager]

Could someone help me out. My computer won't boot even to bios after I tried overclocking my you. It doesn't even boot to bios! Just a black screen everytime I try to start my computer. The last thing I did before it crashed was trying to boost my memory clock then my screen went grey then that's that.
