Asus z77 Sabertooh
Intel i5 3570

My system keeps turning on and off repeatedly. Anyone else have this issue before or could provide a possible solution? I see a red computer LED light on the MOBO which is constantly on while the cpu fan is running. The cpu fan runs for not more than 3 sec and then shuts off. After it shuts off the mobo funs run for 3 secs, rinse and repeat.

I just purchased the components recently and am curious whether it is a mobo issue or cpu?

Sounds like a RAM problem to me. Try pushing harder on the RAM sticks to make sure they are seated all the way in the slot. Even if the clips are up the RAM might not be in far enough.

List the rest of your specs if you would, please.
