Pc won't boot if shutdown for too long

[trexiic]

Hi, sorry for my bad English, I speak French.

My specs:
i7-4790k (No OC)
Asus Z97-E
2x4gb DDR3-1600 Avexir core
EVGA 750W bronze 
Bitfenix Shadow

The problems:
-If I shutdown (same thing with hibernation) my pc and and reboot it <8-10h after, it will boot normally, but if I wait more than 8-10h, the fans and the leds will work, but the screen won't show anything. If I hold the power button, it won't even shutdown! I need to manually reset the power supply at the back of the computer, and then it will boot correctly. It's been doing that for 2-3 weeks now.
-If I put my pc in sleep mode, the fans and leds will shutdown (normal), but 2-3 minutes after, the computer will boot by itself!

Except that, my pc is working fine, and can leave it open for 24h+ and play anygame I want and it won't shutdown for no reason. The psu doesn't smell like burn, I never dropped my pc, etc... How can I know if my psu is the problem? (I can't plug it into another pc).
I looks to me like a bug, and not a hardware issue, because when I hold the power button, it won't close, and except for the boot problem, it works perfectly fine. 

What you guys think?

Thanks!


PS: If there is something you don't understand because of bad English, just ask for clarification and I'll try by best to reformulate

bios updated?

[techguru]

to me that kinda sounds like a psu problem or a ram problem

[trexiic]

Yes I updated my Bios to the last version, still the same problem 

 

Maybe a ram problem, how could I troubleshoot that? (I have 2 sticks on slot 1 and slot 3).

 

I hope it's not a psu problem. The computer is working fine (except for that problem) for more than a month! (no bad smell, no random shutdown, etc...) How could I know if it is a psu problem? How could I troubleshoot that?

 

Thanks!

Can it be the Bios battery?

[techguru]

you could run memtest to test the memory

[trexiic]

Hum, let's say I'm really incompetant, and I forgot my 3 usb keys at school (Yea, really...), is there another way to run memtest on my pc?

Thanks!

I'm doing the test right now. By the way, the sound test almost killed me.

 

I'll post the results once it is done.

 

Can you tell me how to test troubleshoot my power supply?

 

Thanks.

[techguru]

if its the psu...only thing you can really do..without the proper equipment..is buy a new power supply...see if it works properly..if it doesn't you return the power supply..and try something else

[trexiic]

I'm halfway through the test, and I only received sound errors. 

Let's say the problem IS the psu, then why is it working if I shutdown the pc for 5h, but not for 10h? That's weird.

It's a memory issue, I had the same problem, I swapped out my RAM, and it got fixed.

[trexiic]

If I try each of my memory sticks alone, I should know which one is defective, right?

Or I need to try them in another slot?

Thanks

[trexiic]

And if I find that one of my memory module is defective, can I RMA only one of them? Or it must me both of them? Thanks!

RMA as a whole set

Try each memory stick individually in each slot on the mobo. That will help determine if it's a dimm issue or a mobo slot issue.

I'll do that!

But it will take a couple of days, because everytime I'll need to shutdown my pc for 10h to see if it works...

I removed one memory stick. I boot the pc and 2 minutes later it shutdown. I boot it again and it show the "anti-surge" error.

I tried the other memory stick, the pc won't boot.

I installed both of them like they were before, the pc won't boot.

I touch the motherboard heatsink (The golden cercle on the Z97-E, I think its a heatsink), the computer powers on for one second. I press it again, same thing. Now everytime I want the pc to boot, I need to press on the motherboard.... wtf....

I think the real problem is my motherboard now, should I rma it? CAN I rma it if I have already sent them the bar code on the package for a MIR?

thanks!

It's a possibility. Did you take each memory stick and try them in each slot on the motherboard one at a time?

You can RMA the mobo at any time. With the retailer you only have so many days, but after that you can RMA to the manufacturer within the warranty period.

Yes, but I haven't been past 2 minutes in windows (because the computer would not boot/or crashed at desktop) so I can't tell if the problem is due to my RAM.

I've sent an email to Asus tech support for the motherboard, and it tells me to wait 2 days for an answer, so in the meantime, I'll try each stick in each slot (It takes 1 day each to know if its the issue). Maybe my motherboard is deffective AND my ram is cause my not to boot after being shut down for 6h+, or maybe the motherboard is the problem for both.

OK when you've tried each memory stick in each slot let me know. It could be a combination of mobo and ram. Or just the mobo or just the ram, but to rule out the ram you just need to get the computer to post to the bios.

My computer can post to the bios with both stick of ram, the initial problem was that the computer would not reboot after being shutdown for too long. The motherboard is almost surely defective, because when the computer won't boot, if I move the board, it boots. But maybe its not the cause of the initial problem (pc won't boot if shutdown for too long), maybe it's a ram problem, in which case I'll need to RMA both the ram and the motherboard.
