Overclocked my CPU, a day later I get "System has experienced boot failures"

So I overclock my i7 2600k using this guide:

http://www.bit-tech.net/hardware/cpus/2011/01/07/how-to-overclock-the-intel-core-i5-2500k/4

Because I have the same motherboard. As I go through it I realize that I don't have the same BIOS version as the guy in the tutorial. So to keep it safe (I thought), I simply made my clock ratio to 40x (.5 lower than the tutorial) and didn't follow the rest of the tutorial, thinking I wouldn't need to since I only raised it by a little bit. I saved, booted to Windows, ran Prime95 for 10 minutes and thought everything was fine.

2 days later I leave for work and leave my PC on sleep mode. I come back home and boot my pc only for it to shut down and turn itself back on over and over again. I try unplugging and plugging my power and it does it again. I leave it for awhile and it does boot but greets me with this:



so now I reverted back to my default BIOS version and here I am.

My questions are:

-Is overclocking more than just turning up the clock ratio?
-Did I just do some serious damage to my system?
-I admit, I didn't do the rest of the tutorial because I dunno what half of it does so it scared me, do you think the tutorial above is safe and I should follow?

Btw as you can tell I have never overclocked before.

    -You can just change the clock multiplier for "little" overclock, but normally you change the voltage drawn by the CPU to gain stability and sometimes directly the clock ratio.

    -No, it does not seem to. But you could cause some serious damage if you don't go step by step and don't know what are you doing. Try to gather all the info and experience you can before jumping into OC your CPU.

    -I don't know if it is really safe or not, but i don't recommend you to do what it says withouth checking with other sources. Each CPU is a different, and maybe your CPU needs more or less voltage to get stable at certain frequency. Even it could be that your CPU can't reach the frequency the tutorial says.

    Before doing any OC, try to gather all the info you can and draw your own conclusions. Go slow and adjust the multiplier and Vcore little by little to get the best results and avoid this kinf of errros.
  2. Did you clear your cmos by powering off the pc unplugging it set the jummper next to the battery to "clear" position. remove the battery power it on then off and put the jumper back to the original place, battey back in place. I think that is how its done been so long lol

    I didn't raise the voltage at all. I'm too afraid to fuck something up and blow up my PC.

    This is too hard for me. I've read so many different tutorials and every single tutorial mentions things that aren't even in my BIOS so I have no idea what to do. I really want to overclock as well but I don't even know what most of the stuff in my BIOS does.

    Do you think I should just get a non-K CPU?
