    Cannot boot into windows 10


    Pc specs:

    EVGA Classified k Z170 motherboard

    2 asus turbo gtx 1080's

    Intel 6600k cpu cooled by noctua d15

    32gb Gskill ram @2400

    Windows 10 home

    Samsung 950pro 256gb OS drive

    2 Sandisk SSD Plus 480gb gaming drives

    Corsair RM850x PSU

    *

    Yesterday I was playing a game and it froze. It was a complete system feeze not just the game. Did a forced shutdown (held power button). When I*tried to turn it back on it took several attempts to start up. Afterwards I started the game back up to see if it would freeze again and it did after about an hour*of gameplay. Same shutdown method as before but now it will not boot into windows. The motherboard seems to be POSTing. It gives no error codes/beeps just CPU temp as it should and the normal beep at startup. The PC locks up at the "classified k" screen before loading windows. I CAN get into the BIOS. Game was farming simulator 17 which I have played several hours previous to this issue. I havent added any new hardware either besides a new monitor about a week ago. Predator x34 if that matters....

    *

    Things I*have tried:

    1.* *I isolated just the motherboard, CPU, OS SSD, PSU and just one stick of ram and still had the same issue.*

    2.* *I then bought a new PSU and tried that with no luck. Used the new wires as well just to be sure.

    3.* *I then bought a new SSD and tried to boot from original windows 10 USB stick with no luck. I can choose which version of windows I want to use but then it stops at the same screen.*

    4. I have used clear CMOS button and switched the physical BIOS switch on the motherboard.

    5. All wires have been disconnected and reconnected and I*know they are attached properly.

    First thing I have to ask is: Have you been overclocking the computer?
    Second question: If you overclocked, did you push RAM, CPU and GPU to their limits?

    To me your issue sounds like either a RAM or storage controller issue.

    I see you have tried a lot already, but just to make sure do the following:
    1. Disconnect all from your MB expect one RAM stick, PSU and CPU.
    2. Reset BIOS
    3. Disable everything in BIOS you do NOT need, including extra USB ports, audio, LAN/WLAN, if possible (you want absolute bare minimum devices enabled)
    4. Boot up using your USB stick from an USB 2.0 port if available. (USB3.0 may have driver compatibility issues and may freeze)
    5. Can you get past the select OS edition screen into select install location?


    Try booting up to this state using a different RAM stick if previous attempt failed until you get to the state where setup media does not find a drive where to install.

    Now connect a disk drive to SATA0 (or SATA1, depending on the numbering scheme. Has to be the first port for best compatibility)

    Could you get setup media to find the drive?
    Could you install the OS to that drive?

    It is possible that something is halfway fried on your MB so that the MB self diagnostics can't find any issues.

    Thanks for the reply...
    I just went through and disconnected everything from the motherboard but psu, cpu, and 1 stick of ram. I disabled everything in the BIOS and then reset with the USB stick inserted. Clear CMOS was already done multiple times and everything was running stock for test. I chose windows 10 64 bit and hit enter. It goes through two "loading files" screens and then freezes at manufaturer logo screen. I tried all four sticks of ram in all four dimms (Tried the correct one first) and still no luck. Same thing everytime.

    So didnt try SSD as I cannot get to that point. Does this leave just the motherboard as culprit since I have tried a new PSU? Only thing left would be CPU...

    As for your first question, everything was overclocked.
    Both GPU's running a moderate overclock.
    CPU running at 4.6GB but never reaches 60C.... ever. Highest Ive seen is 58C. Even during stress testing.
    Ram had XMP profile enabled so it wasnt really a overclock just what it is meant to run at.

    All temps are always monitored and everything stays well within safe bounderies.

    Did you try these steps with the new PSU or old one?

    It seems like either a MB issue or CPU issue...

    Only thing you could try is to remove CPU, clean MB and CPU, re-install CPU and RAM and finally test again with minimal setup. (the removal of CPU is just to see if it helps solve possible lose connections which sometimes is the ussue)

    Make sure you do it properly or you might fry your CPU.

    If this does not help then trying another CPU would be one option and last one is to replace the MB.

    As a side note: Make sure your wall socket is grounded properly. This can also cause a lot of weird behavior. If possible try to eliminate all possible static electricity from case and MB. (static electricity builds up easily in systems with a lot of fans when the system is not properly grounded and weather conditions are optimal)

    I contacted EVGA and luckily the board is covered under warranty still so they sent me a new one. I will try the new board when I get it and hopefully that will fix the issue. I did pull the CPU and re mount it with no luck. I will update this post after the new board is tried.

    Thanks again for the help.
