Hi, I've just tried overclocking for the first time on my 4770k with a CM Hyper 212 Evo Cooler. I did it in the MSi Z97 PC Mate BIOS, and everything looked alright. I exited out of the BIOS, making sure to apply the changes I'd made. Then I restarted my PC, and all of a sudden, my monitor wouldn't show anything. Apparently there was no connection or something. I made sure everything was plugged in and tried again. Still didn't work. My lights on my keyboard and mouse didn't turn on either when I tried restarting the PC, so that's also an issue. I opened my PC up then and looked inside. It wasn't hot, and nothing looked fried. Tried again, didn't work. What should I do? Please help, and thanks!
