Hey guys!
I have just been away on holiday and recently got back to start my laptop up.

The predator logo appears fans run etc then it goes straight to a black screen. Have tried turning off and on reseting, connecting it via a hdmi to another display to no avail.

I did however an overheating issue about 6 months ago due to a fan dieing and since then have had random screen glitches/cracks. I am wondering if my graphics card has given up? Or is something to withthe cpu? 

Any advice would be great on what to do next.

Thanks

    Try doing power drain and BIOS default  and see, atleast the blackscreen issue might get fixed.
    power drain: Just check the back of the unit, you can find a pin hole , unplug the charger and turn off the unit. now put a paper clip in the small pin 
    hole and press and hold it for 30 sec.
    BIOS default: After power drain is done, power on the u nit, but as soon as you power on the unit keep pressing the F2 key so that it take you to BIOS 
    page. Press F9 and press Enter than press F10 and press Enter. the unit will restart

    Hi@picnic101,
    >> Try to perform a simple power reset and check the issue.  Shutdown the laptop. Disconnect the charger. Disconnect the external display. Please check for a battery reset PIN hole at the bottom of the device.The reset hole would have a battery symbol next to it. Insert a paperclip into the hole and press for four seconds. Let the computer sit for 5 minutes with no power. Reconnect the charger and power On the laptop.
    >> Try to do a bios default. Turn on the unit after the above process->as soon as you see the acer logo keep tapping f2 and you will see a Bios screen. press f9 for a default settings->hit yes,press f10 for saving the setting and hit yes.(use enter for confirming)

    Thanks for the reply christy and jack

    I tried both of your solutions and it still is giving me a black screen. Fans and the light for the disc are still running but nothing else is showing.

    Is there anyway to determine the root of the problem or am I going to have to take it to a shop 

    Thanks

    Hi there,
    Scratch that.

    The computer is now booting after i retried the pin hole technique. Yet it keeps crashing taking me to this screen.

    I have tried system restore, reset pc- says it can not do this, safe mode - still crashes, startup repair. All of them come up with these two errors when the screen stays on long enough.

    Irql not equal to or less 
    Kernal security check failure 

    I have googled solutions and found saying its my video card?
    How can i be sure it is this ?


    Thanks once again

    You can purchase a sata/m.2 to usb (whichever you need for your drive)and plug it into another computer to retrieve your photos.

    And when you manage to get windows up, go to power settings and disable the "fast startup" options. Most windows 10 problems stem from this setting.

    Hi guys,

    Thanks for all of your input, definetley appreciate it.

    So I have disconnected my D drive(2tb) and tried to do a fresh install of windows to hopefully fix the problem.

    Using a CD i go through the options then it scans for drivers. It says im missing a media driver and asks if I want to continue. I Click yes and unfortunatley it says i cannot continue without the driver.

    Any suggestions?

    I have reconnected the d drive but it still came up with the same error. When i try reset the pc it says drive partition is missing. Does this mean my C Drive is broken ?

    i think the drive(ssd maybe) where the windows is installed is needed to be replaced (maybe its dead)

    Try connecting the drive via USB using a cable to a different laptop (there are many convertors on Amazon for less than $10). This should help isolate drive working or not issue.

    Hi@picnic101,
    The hard drive is dead i guess. We can do a GW scan on it to check if the hard drive is working or not. since you have taken the backup you can take it to the local tech.
