Computer turns on then off then on again?

I have an asus Maximus vi hero, I have an overclocked i7 4770k @ 4.3 ghz 1.26, I also have a RAID 0 set up. Which I did around 2 weeks ago, the I install a new fan a couple of days ago, a case fan. And then when I turn on my computer it will turn on for a couple of seconds then will turn off for 4 seconds then automatically back on and will boot fine and the computer will have no problems at all, this happened all of a sudden, my computer has been functioning perfectly since November and now I don't know what wrong with it, I don't want to clear CMOS as I will have to set up again. I tried reseating ram and it didn't do anything. I Rama. Mem test and I got no errors?

  1. You probably installed the fan wrong. Some motherboards have safety features to protect against overheating - they won't boot unless the fans are properly installed (especially the CPU fans).

    I have a corsair h80i which works properly the problem was before I installed the case fan yesterday, the idle temp is a cool 25 degrees Celsius, it's not over heating or anything. Should I try reverting my overclock?

    Yes, I would set your BIOS to default settings. Make sure you know how to change everything back though. This is just a hopeful fix.
  4. Will clearing CMOS erase my RAID array? Will I need to format my drives to get it back to RAID?

  6. Thanks, I'm going to wait for more answers for a while
  7. I had the same problem a while ago. Try booting with only one stick of ram and on the farthest slot from the CPU
