I get error code 124 after going from the OCgenie oc which is a factory overclock to my new overclock that i did myself after taking notes from this video from youtube, Overclock 4770k. I noticed that I when I opened youtube it gave me the blue screen, I'm not sure if this is a hardware issue or a temperature issue. My cpu cooler is an Hyper X Evo 212, I suspect that its a temperature issue but my cpu core temps when i check before i crashed were in the 40c's so I believe that is normal temps according to the overclocking guide on this forum.
