Asus P9X79 Boot issues after forced shut down or power outtage.

First of all. This rig never made a beep on start. I've found strange in the beggining but didn't complain. Kind of felt like a all around silence update coupled with me having an SSD now.
Now, I actually suffer with it because I have no diagnostic beeps.

Ok, so the computer always boots fine. But when there's a forced shut down (pressing box power for some seconds) or a power outtage (some times people turn a lot of stuff at the same time) I can't boot the computer for like 15 minutes or more:
- Screen is black and enters power save mode after a while.
- Mouse and Keyboard have no energy.
- No beeps just like on a successful boot.

Today I got more worried since waiting didn't do the trick. So turned off the PSU, waited 10 minutes, opend the box and pressed MemOK and then it finally booted

Rig Specs:
Motherboard: Asus P9X79
CPU:Intel Core i7-4930K 3.4GHz 12MB Sk2011
GPU: Asus GTX760 2GB DirectCU II OC
RAM: Kingston HyperX Blu DDR3-1600Mhz 2x8GB
PSU: Corsair Builder CX600W

It hasn't been an year since I bought it. Should I contact the vendor? I didn't meddled with overclock or anything. Mostly stock, only change the boot order. The CPU seems to be OC, 3.9? Not my doing though, I usually OC nothing, in favor of durability.


Thanks in advance

Cheers

I'd send Asus a note about your motherboard, as sounds to be contributing (or the factor) to the issue.

Damn today computer freezed up. Forced shut down. An now I cant turn it on for the life in me... usually after 15 without power it works ok.

Red light shows... nothing happens. Seen some threads. Took of battery, pressed memOK, nothing. Ram sticks are in the correct place... dunno...

I can't work... =;(

Ok, so apparently I better wait 30 minutes now 😉

Posted. The image shows the sequence of a successful post. When I find myself in this stretch it doesn't go beyong 1.

Do you have access to a better PSU you could try with it? The CX series is noted to have weak caps, which might explain having to wait to start back up
