Computer boots twice, normal?

post #1 of 11
Thread Starter 
I just built a new computer specs are on sig.

No overclock done yet, so everything is in stock. When I press the power button it turns on for a second turns off and then turns on again and loads. So basically it boots twice, being the second boot when it actually loads and goes pass the Bios and into windows. Can this be a problem?

Sometimes ASUS boards do that. Mine does it too.

Really that's a sigh of relief so it's normal right? Your not having any problems with your comp other than it booting twice?

Yep mine did it too. It stopped randomly. I did do some of the things in this thread though to help fix it: http://www.overclock.net/intel-motherboards/1012874-official-asus-p8p67-p8z68-p8z68-gen3.html

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.

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

yes if you want to get ridd of it just disable PLL overvoltage from bios under A.I something in advanced mode. Also if you are having problems from dedecting your hardware if you are not using Marvell controller you cand go ahead an disable that too under pcie devices from advanced tab.

All my Gigabyte EP45-UD3P's do that, start-up for 3 seconds or so,shut-off,then start-up and finish the boot process.I never have looked into it.This is just like my ASUS P6X58D-Preminums always say "no hdd detected",then go ahead and boot. It does not bother me but I guess you really could not sell one to someone that did this (unless you can explain real well)

Yeah, I have the same mobo. It happened to me from time to time as well. It wouldn't POST twice, but it would power up for a few seconds, and then do a hard power reset and boot. I don't recall having the issue since I updated the BIOS, but to be honest, I've changed so many settings in the BIOS and tweaked my system so much I'm not sure what got rid of it. It didn't happen everytime, usually when it was down for while and was in a cold state. Are you overclocking your cpu? Your BIOS up to date?
