PC boot up problem

Brudarion · Oct 25, 2016

Hi guys

I have encountered a weird problem. The past few weeks this rig performed amazingly but last week and today again I had a problem where it did not want to boot up. Last time it was as simple as unplugging the power cable and back in and i booted by pushing the power button on the motherboard but this time I had to almost undo everything and I followed steps on a site and nothing worked up until the end where I was about to give up and just buy a new PSU and hope for the best, I plugged everything back in and it worked again when I wanted to test it out one last time. I'm just afraid if there will be a next time it will be more annoying and I would like some troubleshooting tips.

The exact problems were as follows: everything was plugged in correctly and have used the computer for weeks without problems and then one random day it just refused to boot up. The motherboard still had lights on it (asus logo and power switch on mobo) but aside from that it refused to boot.

This is my current setup:
CPU: Intel Core i7-6700K 4.0GHz Quad-Core Processor
CPU cooler: CRYORIG R1 Ultimate 76.0 CFM CPU Cooler
MB: Asus MAXIMUS VIII HERO ATX LGA1151 Motherboard
RAM: Corsair Vengeance LPX 16GB (2 x 8GB) DDR4-3200 Memory
SSD: Samsung 950 PRO 512GB M.2-2280 Solid State Drive
SSD: Samsung 830 Series 256GB 2.5" Solid State Drive
HDD: 2x Samsung Spinpoint F3 1TB 3.5" 7200RPM Internal Hard Drive
GPU: MSI GeForce GTX 1070 8GB Video Card
PSU: Corsair Professional Gold 850W 80+ Gold Certified Fully-Modular ATX Power Supply
Optical drive: LG GH24NS90 DVD/CD Writer
OS: Microsoft Windows 10 Home OEM 64-bit
Case: Fractal Design Define R5 Blackout Edition ATX Mid Tower Case
Case fans: 3x Phanteks PH-F140HP_BK 2 88.6 CFM 140mm Fan
Mouse: Razer Naga/Razer Deathadder
Keyboard: Razer Blackwidow Ultimate

Would appreciate any help or advice thank you.

What is the exact PSU model?

Have you changed anything in BIOS setup?

Brudarion :

Here are some ideas,

-disable hibernation on your computer. lets start with that, as your symptoms sound like a pc not waking from hibernation.
1) open the command prompt (in administration mode)
2) type 'powerconfig /hibernate off' without the ''

-if that does not help, try hitting the MEMOK button on your motherboard

-you can always try a bios update if you haven't done one yet.

-remove the gpu and see if the problem goes away; not many things can stop a pc from booting, the gpu and ram are no.1 and 2 on the list though.

-replace the psu, if the ram and gpu are no.1 and 2 on the list of suspects, the psu would be no.3

-replace the motherboard, and this would be the next suspect if it's a hardware issue.

Hi guys

Small update here as I've had it happen yet again! I just went to a restaurant and came back (pc was in sleep mode) and refused to start up yet again. Had to switch contact plugs again to make it boot up. I actually tried booting without GPU and RAM and nothing worked when it refused to boot the second time.
I have not done a BIOS update yet as it confused me last time i tried it. I had to flash my previous mobo and from there on I had so many problems after that it broke down (granted it was 4 years old). I did do some minor tweaking so the RAM actually operates at 3200 speed as stated on the box. If not it was only in the 2000s. Something to keep in mind is the PSU is 4-5 years of age now but still it is a quality piece in my opinion. Not exactly sure how to disable hibernate mode because I'm on windows 10 and pretty new with this OS.
If I'll have this issue again tonight and or tomorrow I will write down my model number and would like to go further into detail. In any case this is pretty frustrating of this happening to my PC which isn't even a month old.

Right click on the Start button (opens the Start menu when left clicked), select Command Prompt (Admin), type in powerconfig /hibernate off and press Enter. You can then close command prompt. Restart to apply changes.

Brudarion · Oct 25, 2016

Sorry to sound like an idiot or something but for me it doesn't work and I get 'powerconfig' is not recognized as an internal or external command, operable program or batch file.

weberdarren97 · Oct 25, 2016

Okay, I'm going to leave this open to someone who knows a little more about cmd. It seems I've given you an invalid command.

Sorry I wasn't more helpful.

ingtar33 · Oct 25, 2016

Brudarion :

powercfg /hibernate off

that is the command

Brudarion · Oct 26, 2016

Ok I entered the command and I did not get any feedback. I guess its good because last time I got feedback that it could not recognize the command I gave it. In any case it happened again today but this time my pc was completely off and not in hibernate. I have to switch contact plug and plug out the power cable and put my psu off from the back then put everything back on and boot via mobo. Very inconvenient. I'm starting to think my PSU is starting to fail. Can anyone confirm this as a possible issue?

weberdarren97 · Oct 26, 2016

Yes this sounds like a possible PSU issue. Do you have an active warranty on the PSU?

JakAzz425 · Oct 26, 2016

Pull the FPanel Connection for power button and reset button, sounds to me like your front panel cables to your power button are messed up and causing the pc to freak out. Long shot but thats what it sounds like to me.

Also, do you have another PC that you can use as a test bench PC? One you can test parts in?

Brudarion · Oct 26, 2016

Sadly I do not have a warranty on this psu anymore as it is about 4-5 years of age. If i pull the front power switch cable off that might be very inconvenient too considering that i would need to open up my pc every time i want to boot it. Any work arounds I'm unaware of?

JakAzz425 · Oct 26, 2016

just for diagnosing the problem, if that ends up being the culprit, yea you would need to trace the wire to see why its bad, maybe a kink or broken wire, might be in the button itself, if so easiest approach, if you dont want to repair the wire, get a new case. BUT, this isnt for sure the culprit, just trying to knock it off the list of possible causes ;-)

Brudarion · Oct 26, 2016

Thing is my case is very new and I doubt this is actually the cause. Because when trying the mobo boot button it doesnt work either. I always need to kind of put all the cables out of the pc then redo it and also unplug it and just in general being sure the electricity is completely gone and then redo it, then it boots.

JakAzz425 · Oct 26, 2016

Did you use all the mobo standoffs? cause if your having to fully disconnect everything you might have a short somewhere

Brudarion · Oct 27, 2016

sorry for being a complete noob here but what exactly do you mean with the mobo standoffs? (english is my 3rd language, i might just not understand that phrase

)

JakAzz425 · Oct 31, 2016

Sorry for the late response, been hectic. Motherboard standoff's are the hexagon screwhead bolts that you put into your case, they are what you screw your motherboard down to to attach it to the case. They also are grounding points for your motherboard, so if there is one that is contacting the board intermittently, however slim the chance that this could actually happen, there is a chance things could go a little screwy, (pun not intended but im not going to remove it). So that would be the next check.

Also, you said you changed drives to no avail, did you clone the drive? or was it a fresh drive with nothing on it?

Brudarion · Nov 3, 2016

Sorry for the late response as well. I did use all the standoffs for the motherboard. I found a workaround for now which is whenever I turn off the computer I flip the switch off on the psu. Not practical or nice to flip it on and off every time but for now it works which confirms it for me that it might be the PSU.
