" rel="nofollow - This board is great. stuck an i7700 on there and 16gb of corsair ram. has a 960evo. 600 bronze evga and 970 evga ssc so the problem is that if I ctrl-alt-del from bios, it will reboot. any other time it tries to reboot (software install, windows reboot, shutdown, paragon boot disc reboot or shutdown, etc) it freezes right at the point it is going to reboot and NEVER DOES. Is this typical for this board? Is there something I can track down/change to get this behavior to correct? Thanks! |

" rel="nofollow - Never CTRL+ALT+DEL to exit from the BIOS. That is asking for problems. As for "any other time' , look closely at the wiring leading from your case to the System Panel Header on the MB that the polarity of each wire/connection is correct. Too, is it freezing, or maybe entering hibernate or a sleep mode? Is anything still spinning and or lit up when it freezes? |

That I spoke is assuming this is a new build. |

1. new build 2. os not installed yet, just observations of when it tries to reboot when installing os (still messing around with partitions from old drive) 3. ctrl-alt-del from bios was just a test to see if it would reboot 4. polarity correct. I can power down with the button and reset with the button, this is only when "software" driven 5. HELP! :) I know this will get annoying down the road so I hope someone can point me to a solution!!! |

That! Instead of booting from a drive with drivers and apps from your old board, use another HDD/SSD to test with a fresh OS. Or if your familiar try using a Live Linux distro to boot from and see if it behaves the same. My guess is it doesn't and instead shuts down properly as every install file is kept in memory. |

" rel="nofollow - I guess I need to post more info. so I've installed from scratch just to get the drivers cloned off to apply to the old partition. here's the drill on the experience: 1. booted to win10 installer 2. installed and after 10sec timeout to reboot, it froze 3. hard shutdown (hold power) and turn back on 4. continued windows installation. windows wizard. desktop. 5. start --> reboot = freeze 6. start --> shutdown = freeze it always happens right when I would think the board should be "popping" it back to post bios. I haven't finished the driver clone swap and have paused in hopes we can figure something out before I finish?!?!?! :) THanks for helping! |

additionally, when I boot to an ultimate boot cd or paragon, the "software" reboot/shutdown does the same behavior. :) |

I'm sorry, but your descriptions of the situation are confusing. No, what you are describing is not typical for this or any board. So you have a 960 EVO, which I assume will be the OS drive for the H270M-ITX/ac? What is the Windows 10 installation media you are using? Optical disk, ISO file on a USB flash drive? What entry in the boot order are you selecting for the Windows 10 installation media? There should be two. You need to select the entry that is, "UEFI: <installation device name>", for a proper OS installation on an NVMe SSD. Then you said this: "so I've installed from scratch just to get the drivers cloned off to apply to the old partition.". What does that mean, drivers cloned off to apply to the old partition? Are you trying to clone a partition from another OS installation to the 960 EVO? If you installed Windows 10 on the 960 EVO with any other drive (besides an optical drive) in the PC and powered up, then the Windows installer will put the boot/system partition on another drive. If the other drive had an earlier OS installation on it, who knows what you ended up with. I do know it would be a complete mess. Even worse, if the other OS drive was from a different chipset board, cloning drivers or whatever you were doing is a big mistake. Given what this all sounds like, I wouldn't be surprised that some of the things you described are happening. You should either install Windows 10 on the 960 EVO with no other drives in the PC during the installation. If you are hoping to clone a Windows installation onto the 960 EVO, unless you had another NVMe SSD in that PC, you won't have an NVMe driver installed, and the result will not work correctly. Please try to explain what you are trying to do with your new OS installation. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

" rel="nofollow - OK. I do not mean to sound confusing. So I have the following: H270M-ITX/ac motherboard 2x8gb corsair vengeance LPX DDR4 3000 intel 7700 h80i v2 corsair 960 evo m.2 600b evga ps 970 evga ssc video -------------- Lets set aside me bringing my ssd to m.2 (which I've done several times, completely unrelated to this) to boot from gpt instead of MBR. -------------- empty system. insert the usb windows 10 installation. lets set aside the issues installing because it doesn't reboot. now we are in windows. I've loaded the inf drivers. let windows update handle the rest. (i've tried this with all the drivers from asrock as well) so now that we are in windows, no device manager devices are missing or errored ok. begin the troubles. -------------- If I try to go to start --> reset, it says "shutting down" then black screen and it freezes. bios does not repost and it doesn't reboot if I try to go to start --> shutdown, it says "shutting down" then black screen and it freezes. the machine does not shut down if I hit the power button to initiate shutdown, same thing happens as above. if I hit the reset button, it resets properly. if I hold the power button, it shuts off properly. -------------- What do you think could be causing this? Thanks! apologies for all the confusing things on the sidelines of this build. :) |

it was the placement of the reset switch. if you look at the front panel header pins, there's a row of 5 and a row of 4. the row of 5 contains the reset + hard drive led. hard drive led and reset were tightly linked. putting the reset switch over one "peg" to create a peg of space between the two fixed the problem. Thanks! |

That is weird, the reset switch would only short if it was pressed but hey, glad you got it working  -------------

" rel="nofollow - Hi Guys! I have boot problem as well. New h270m-itx/ac board. No additional vga, i5 7600k, kingston ddr4 16gb 2133mhz (in one slot)... Can't boot from dvd, can't boot from pendrive. When i try the result is the same: Windows dows logo appears and the machine gets frozen.. tried Windows 10 and 8.1 bootable usb made with rufus... Reset switch not connected...

I have the same issue - but I think the problem is with the motherboard. I recently purchased 40 of these motherboards, building identical units. Ram = corsair 16gb, i5 kaby lake. out of 20 builds, i have two units that will not software reboot. They will software shutdown - but will not restart. i have tried unplugging the reset switches on these two problematic units. Other units are identical (all machines are clones) and the others reboot properly. my next step is to swap out RAM on the problematic units / then swap out the CPUs. However, I strongly suspect that the problem is with the motherboard. |

" rel="nofollow - Kid and Bama, If you make it to the Windows "loading' screen IMHO that implies POST has finished, leading me to believe this could be maybe a one off flaky install Are your BIOSes up to date? The latest is 2.00. Bama, where these parts bought at the same time? Swapping out the mem in those two would be what I'd be doing too. If swapping corrects this, fire up the offending sticks and using Thaiphoon Burner look to see that the offending sticks are the same IC's. |

thanks wardog. I ended up having 9 motherboards (out of 50) that would fail to reboot. This effectively ruled out hardware issues because no company could possibly have such an abysmal failure rate without a recall. Our shipment was a mix of 1.10 and 1.20 BIOS. 1.20, oddly enough, was the version that would hang on restart. Updating BIOS to 2.00 fixed the restart problem. hopefully that helps anyone else with that experience.
