PC only starts 1/10 times

[culzone]

Have gotten this problem for 2 weeks. I turn on the PC all the fans spin up but my keyboard and monitor does not start, also I have my headset connected and can hear that im not getting into windows.
So i restart, restart, restart and then one out of ten times it starts. And when it starts there is no problem at all, heat is fine can run all benchmarks and stuff, PSU is 1 month old.

Here is my full system aswell so you can see all my components!

Run some stress tests once it boots to see if it's a power supply issue, and disconnect your non-boot drive just to remove some factors to narrow down the problem.
Is it thermal related?
When you CAN manage to boot, check your CPU temps, could be that the cooler is not making optimal contact with the CPU IHS.

I get 72C in prime95, ran it yesterday for 4 hours and played games for like 6 hours. the computer never shuts down while it's finaly turned on. Also I got the same cooler as you! 😀 kraken x61

Aaay, great cooler! 😛
This sounds like an issue with your boot drive, are you running it off the v300 or the 850 Evo?
The v300 is a very poor quality SSD, and can be extremely unreliable.
Do you have any HDDs? 😵

I run it off the 850 evo and the v300 was my boot drive some year ago, and no I don't have any HDDs.
I've been thinking about reinstalling windows do you think this might help me?

 

[Chugalug_]

No it wouldn't help. 🙁
You DEFINITELY need a HDD for any build for storage for games etc.
Your SSD should only be used for OS and software with the exception of maybe a few games like CS:GO where you may want faster loading times.
Try boot without the v300 attached and see if it works.

Tried without the v300 attached and it did not boot :/
I have like 10 games on my 850 evo and like 5 games on the v300 and ALOT of programs. 40gb/250gb free space
EDIT: But feels weird since my computer had no problems with this for several months

I assume you haven't changed anything before getting this issue?
Double check that all wall and cable connections are fully plugged in, and replug them as often this can be the cause of boot instability.
Are you getting a splash screen on these failed boots?
Or does it just start and then die?

it starts and never goes off. It's just that my screen and keyboard does not light up.
No blue screens.. well nothing at all on the screen
EDIT: one weird thing is that if I unplug anything in the PC like a ram stick or something then it boots always one time, and if I plug the ram back again I can start it just once again, and if I reboot without unplugging or pluggin in something then. it's F**ked again

 

[Chugalug_]

Wait wait, please explain what you mean.
Are you unplugging components WHILE booted?
That's extremely dangerous if so. 😱
It may be a faulty RAM module, is it always that specific one?
Remove that single stick, and try booting multiple times.

Hahaha XD no I turn it off while unplugging components haha. doesn't matter if I unplug the video card or a ram stick (any ram stick) or like the v300. It always boots one time. And then after I press "turn off" and try again to boot it won't work

 

[Chugalug_]

Very strange issue. :/
I've never encountered anything like this so the only solution for now seems to be to continue unplugging and replugging components or doing a CMOS reset of your motherboard which will revert any settings or overclocks.
That's the only path I see unless anyone else has any suggestions. :/

well now that we have spoken about it, it does really feel like the boot drive is the problem here, so maybe I should try to put an OS on the v300 and try if that one is having problems booting the PC

 

[culzone]

Still got this very annoying problem, any other suggestions? Tried to reset CMOS so all my settings went back to default. That did not help either.
Today the computer didn't even want to turn on and I tried over 30 times. (wihtout pulling any components out), So I think the only thing to make it start now is to unplug a component and then start

Nope, i'm all out of luck, very strange issue. 🙁
You can contact your mobo manufacturer for help I guess, but I'm not sure what the issue is.
I think I forgot to ask, but what PSU do you have?
