Spent about 2 hours online yesterday with ACER helpdesk and the guy just managed to help me to turn the laptop into a more unresponsive paperweight. We did a reset that was successful but the reinstallation of the OS fails at 9% The laptop is now in an infinite loop of starting up; trying to load; getting a BSOD (now yellow screen and pink screens of death) with a DPC watchdog violation error.
I tried to create a bootable USB device with the older version of Windows 10 on it (I succeeded in that at least) but when I try and boot from the USB it tells me that there is no option to boot from a USB device. I also tried to roll back to previous version but it does not allow me. I tried to install from the 3 different windows versions it has stored in the secret partition but it runs into issues each time and aborts the installation. Does anyone have any advice?

    You dont need same windows 10 version tho, and I would advice against installing newest version, especially since its this version which created problems for lala.

    Rest of advice is top notch :)

    Thanks for the detailed instructions. I was reading a few older posts and found that most of the guys recommend RUFUS to create the bootable USB and that seemed to have done the trick.

    Another possibility to convert the pendrive to boot is using powershell as administrator! To do this, just enter the following commands: diskpart, list disk, sel disk x (x is the number of pendrive), clean, convert gpt, create partition primary, format fs = fat32 quick, assign! After typing these commands, simply paste the windows files to the pendrive and to boot, press the f12 or f2 keys on the notebook! You do not need rufus!

    OK installed all the ACER drivers now and everything worked fine. Left the Nvidia driver for last. Even did a reboot before loading the Nvidia driver. The Nvidia was version 388.31 as suggested and after it installed I did another reboot and it froze and gave me a BSOD, and back into the loop we went. I am going to uninstall 388.31 and just stick to the ACER drivers...apparently I am not allowed shiny Nvidia drivers :anguished:

    try this.
    Also - try to install first old drivers for intel graphic driver, if it doesnt help try with newest - its common that on windows 10 nvidia and intel gpu dont work well together.
    If everything fails you can always try windows 8.1, it could also save your skin.

    Also if your computer is on warranty i would consider sending it to repair.

    Also, what bios version do you have on laptop?
