    I don't really know where to start with this. This is also my first in here for years but anyway, I have a problem with my laptop that I would like you guys to hear.

    It started when I simply close my laptop to put it to sleep. The next day I see that the laptop actually never shutted down but is stuck on a black screen. When I restart the laptop, it not longer boots into Windows 10 and I only get a black screen.

    When throubleshooting, I removed every part of the laptop one by one ( GPU, RAM, USB, Drives ), updated the BIOS, but that didn't fix the problem. I then tried to plug in a bootable usb key to reinstall Windows 10, but even that didn't work, it stays stuck at the windows logo, same thing with a windows 10 dvd.

    I then tried to put in my old Windows 8 dvd and to my surprise it works. I can install Windows 8, install my applications, play games with my graphics card and everything works fine super fine. It seems that my Windows 10 is simply totally broken and I don't know what I can do to fix this.

    Did you make sure to set the uefi/csm/legacy settings the same in new bios

    Yes redownload win10 image would be something to try

    Also play some more with swapping ram around to check a stick or slot hasn't gone bad (memtest too to check for errors)

    Might be worth opening it up and giving it a clean (around pch mobo traces sata ports etc)

    Well you seem to have found the solution of your problem, possibly some windows 10 update which messed somethjing up.

    But I don't know what's the real cause of this. I can't boot Windows 10 from a drive, a bootable usb key or a DVD so I'm pretty much locked out of Windows 10 entirely

    Edit: Also memtest passed at 100%.

    Edit2: Tried the Windows 10 bootable usb key on a second computer and it works well.

    Edit3: Did a reset of the BIOS, same problem.

    So now when you try and boot windows 10 from the installer you just get a black screen?

    Yeah that's pretty much it. Sometimes I see the logo but it hangs everytime, so right now I'm pretty much stuck with Windows 8.1.

    One thing I noticed, when it hangs, the NumLock light indicator goes on.

    When did you create that bootable pen?

    Is it the most recent Windows version?

    It is with the most recent Windows version and I created multiple versions with the Media Creation tool and Rufus with the iso.

    I tested the bootable usb key on my Windows tablet and it works well but on the Sager laptop it simply doesn't boot.

    Sleep is garbage on W10 so I recommend never using it no matter how convenient it seems. That said, I've noticed that sleep/hibernate issues are related to the Intel graphics in many cases, so make sure you're also reloading those if you're doing anything with GPU drivers. There's something about how they hand off/take control of the system graphics that does not always play nice with sleep

    This seems to makes sense, since it always started when I my sleep went on sleep. By reloading do you mean by updating the drivers? Or should I do something in the BIOS?

    I'm currently using the laptop on Windows 8.1
