so i recently did a first time build and all was well until i noticed that if my computer loses power it wont boot and all i get is no signal and the fans gpu and cpu all running fine, this usually happens until i try to turn it on and off a few times usually the solution is pretty inconsistent and it seems to fix itself . I think it may have something to do with the cmos battery possibly because i lose my date and time settings and have to manully select my boot drive also if the pc loses power. Im no expert though so i wanted some thoughts on what this could possibly be caused by. Other than these problems this computer has been running great for a few months now and runs fine when i get it up and running so i would like to think the solution would be something simple and not damaged hardware.
Pc wont boot after losing power completely

hi
I encountered same problem, losing boot drive, loosing the bios profile, date & time, whenever the power was cut or the psu switch was off (e.g. when working on the build, adding drive, etc).
This was on a new asus rampage formula x48 (new as in manufactured in April 2008, bought in Aug 2008).
Took me some years to change it
but after that, all was was ok, no such issues since then.

im gonna try that, it seems to fix itself after trying to turn it on and off a few times and holding the power button for about 30 seconds when its unplugged, but sometimes that doesnt work. I got it back up and running today by unplugging some case fans from the molex adaptor then holding the power button for 15 seconds, but sometimes that wont work and idk if thats what even did the trick, im just really hoping its the cmos. If anyone knows a definitive way to force a POST on a pc with this problem in the meantime that would be awesome.

mine is an asus m5a97 r2.0, did you ever have issues booting after power loss, such as monitor getting no signal but all fans on cpu gpu and case are running fine?

Sorry wilikers, never encountered such behavior.
Not really familiar with your specific motherboard, but from pictures i understand it is not having onboard video.
By any chance do you have multiple graphics cards? maybe video signal goes crazy during first boot after a power loss?
Multiple monitor setup?
If that's the case, try to simplify your configuration till you identify the culprit.
Does it boot into windows even if no video signal on the monitor?
Anyhow, take the problems one by one, fix the first issue (hope it's the battery) then only aim for this video signal issue...

yes your correct it has no onboard video, and im only using one monitor and one gpu. and like i said it loses all the bios settings so i have to manually select a boot drive when i do finally get it running so im pretty positive it doesnt boot to windows. Im going to get a new cmos battery asap and hopefully that fixes this shenanigans.

This is what is exactly happening to me, power but no boot, same motherboard
No i never got around to installing a new cmos cause it hasn't been a major issue anymore since i figured out an easy workaround, if you unplug your computers power cord and the power strip its plugged into then re plug everything, it usually starts up first or second try, idk if it has something to do with there being electricity still flowing through the cords when they are left plugged in but this seems to work like a charm every time.
Same problem dude.
I fixed it by playing with Jumper pins on MB (motherboard). You know the tiny plastic thing that only covers 2 of 3 its pins. It has tge size of an apple seed. It's color and location may vary deppends on the MB brand, sometime near the graphic card and sometime near the processor.
Here's what you should do (according to my experience) :
1st, turn the PC off
2nd, find that Jumper
3rd, move the plastic thing from the 1st and 2nd pins to cover the 2nd and 3rd pins
4th, turn on your PC (there should be nothing apear on screen)
5th, wait till it shuts down itself
6th, return the plastic Jumper to it's original location
7th, turn your PC on
8th, play games, do some work, and do anything you usually do
9th, thank me
PS : this may or may not work on your computer so please do it on your risk.
If that won't work it may have something to do with your PSU but I don't know how to fix that
I hope this will help
