Solved Fresh PC only has issues with 'warm' reboot or power-on?

January 26, 2015 at 04:24:28
Specs: Windows 8.1 Update 1, Core i7 4770K / 8GB DDR3 1600
Hello all,

As of late my system seems to have a very peculiar and reproducable complaint when it comes to rebooting/powering on.

Does not work:
- When the PC was powered on and i hit 'Restart' in Windows for a reboot. It will no longer POST after having been shut down.
- When i try to power on the PC again immediately after this happens it will fail to POST as well.

Does work:
- Resuming the PC from sleep mode works fine every time!
- When i power down the entire PC (hit the power switch on my PSU), hit my power button a few times until all the LED's turn off... then wait like 5 or 10 minutes. Switch the power back on, on my PSU. Hit the power button again. The PC will boot up flawlessly!

I have seen this complaint a number of times years ago (back when i was still in the repairing business). This was usually solved by replacing the mainboard or PSU (assuming it was caused by some bad capacitors or something). Then again... my build is around 10 months old, so pretty 'fresh' and all the hardware is A-grade.
So, I wonder..... if this is a very 'common' complaint one of you guys have heard about before or seen very often as well?
(I think when i was still working with repairs like 8 years ago... i saw this complaint for about 1 out of every 25 PC's that i repaired and they were usually quite a few years old).

Troubleshooting:
If any of you have a better idea of where this complaint would come from exactly, i would love to hear so!
So far my idea of troubleshooting would be systematically replacing one of the components i consider as the culprit to see if the complaint will go away.
If one of you has a better hunch, please let me know!

System specs
To give you some more info about my rig, here are the system specs:
CPU: Intel Core i7 4770K

Mainboard: Intel Desktop Board DZ87KLT-75K
RAM: 2 x 4GB G Skill Ripjaws-X DDR3 1600MHz
PSU: Seasonic X-850 Watt PSU (80+ Gold)
GFX: MSI R9 290X Lightning edition (I do wonder if this heavy graphics card could be a cause of the complaints as well?)
HDD1: 4 x Sandisk Extreme II 120GB SSD's in RAID0
HDD2: 2 x Seagate ST4000VN000, 4TB in RAID1

The system has never been overclocked in any way.

I've seen similar problems here but none that I recall had a specific solution.

One thing to check; if you have any USB devices plugged in when you do the reboot, make sure they're disconnected. Sometimes there's boot problems when they're attached even if they aren't boot devices.

Other than that it's probably as you suggested--power supply or motherboard.

A long shot is to discharge the motherboard, like this:
Turn off computer, disconnect power and remove the main battery if it is a laptop, then hold the Power Off/On button down for at least 20 seconds before reassembling.

I've not run into the symptoms you describe.

Always pop back and let us know the outcome - thanks

I seem to recall driver issues sometimes causing that. See if you can boot to safe mode and then try a warm boot from there.

@ Derek: Thanks for your suggestion, but how exactly does that help me? My first post already states that i have problems warm starting my PC. After any type of proper discharge the PC boots fine (i have already established that), but this is in no way a permanent solution to the problem. :)

@ DAVEINCAPS: Thanks for your reply, i have hooked up a seperate drive to my PC and did a clean install in some cases the machine already failed too boot during a restart (so this is without any additional drivers or software installed... installing all necessary system drivers did not change the situation).

No one here, that has seen this specific complaint before? :)
I still feel this is a definite fault with a hardware component such as a capacitor or PWM regulator...
