After reseating my CPU, my computer doesn't post the first time but restarts and posts the second time, lolwut?

So yeah, my ASUS P8Z68-V Pro (Although I don't think this problem is motherboard specific) posts the second time after I press the power button. So like after I press the power button on my case, the computer turns on for 2 seconds, doesn't display anything and turns off, and then turns back on and posts. All I did was reseat my CPU because I wanted to reapply my MX-2 because I over did it last time and now my load temps are 20*C cooler. So yeah, anybody know why this is happening and what should I do?

Does it keep happening over and over? Or just a one time occurance?

Reseat your memory.
Also try resetting the CMOS.

Isn't that the cold post issue or something.
I had the same thing on my ASUS P8Z68-V Pro

From the ASUS thread 2 possible fixes.
Quote:
Some of you may have been experiencing a double POST on your P8P67 series motherboard whereupon after powering on the system from a cold boot, the board will power on and then immediately reset itself before it actually POSTs and shows any display on the screen. I’ll explain the fix below and give some information about why this happens.

First, I would like to stress the importance of flashing the BIOS to the latest BIOS revision as listed on our support website, http://support.asus.com/download. You can access the ASUS EZ Flash tool from within the UEFI (advanced options, tools) to flash the BIOS from any removable device such as a USB flash drive.
From time to time we needed to implement full resets in order to maintain stability due to the architecture of the Sandy Bridge platform. For instance, the system may require one full reset when the PCH power has been cut during S5 power state. To fix the most common additional reset (double POST when powering on from off state), enter UEFI BIOS -> go to ‘Advanced’ tab -> go down to ‘APM’, press Enter -> enable the “Power on by PCIe.” function. Then press F10 to save & exit. After save & exit, let the system boot into Windows or other OS, then perform a proper shutdown: Start button -> Shut down. You will no longer have the double POST. We will fix this in an upcoming BIOS release.

Another possible solution.

Was having a problem with cold boots, would power of and on and off and on then finally post. I was almost positive it was my power supply because the same thing happened with my UD7 low and behold it was the setting highlighted by the cursor below.

Internal PLL Over-Voltage-Disabled , no more cold boot problems !!!

I am stressing this right now!!! If you are having cold boot up problems with system looping on and off, disable this and it will more than likely solve your problem, although it is sometimes needed for high 48+ multi clocks!

Same thing happened to me after ocing, specially after a cold boot. clearing cmos fixed the problem, unplug the power cable, and turn off the psu, the idea is to drain all power from the mobo's capacitors, then restart your system

also, you might have actually screwed you heatsink on too tight, which happened to me before

I had this happen to me too. I had my Video card burn out (literally... there were scorch marks on the board). I completely disassembled the entire rig, then found out it was the video card. I reinstalled everything again (sans teh card), and powered it on. It kicked on (fans spun up), then shut off 3-4 times before it finally indicated that teh PCI slot was empty. After putting in the new card, it did the same thing, then after that, she boots normally.
I'm running a P8Z68 Deluxe/GEN3 btw...
TL;DR It does that a few times for me, working fine now

I think it has to do something with my heatsink being on too tight. Can there be any permanent damage done from screwing it in too tight?

Rep to all of you guys once I get home wink.gif

There could be if you screwed it really tight you should look for any bend pins thats where the damage will be if it was damaged. If the pins are bend the only thing you can do is try and bend them back. But i doubt they will be bend.
Keep us updated

no, not unless its just insanely tight, when mine did that, i slowly loosened it by about half a turn on each screw until it my OS would boot, however, if that doesnt work, pop your CPU out and check for bent pins, realign them, and reseat
