Black Screen At Boot.

[JJL Computers LTD]

if my computer has been turned off overnight when I try to turn it back on the system posts and then starts loading windows for about half a second and then stops and 2 of my 3 monitors say no signal and the system won't do anything, if I then use the reset button the system boots up normally into windows like it should.

this happens whether I leave the PSU switch on or off overnight.

I have also reset the bios which makes no change.

Specs

• Intel core i7 8700k
• 16gb ddr4 (2x8)
• asus Z370f
• asus Strix gtx 1060 (6g)
• 2x m.2 250gb SSD
• 1x 500gb SATA SSD
• 1x 1tb HDD
• Corsair 850 watt psu

Any help would be appreciated.

It's an option in your UEFI/bios, usually you find it in the boot section, though on my board it's listed under hardware configuration, so you might have to hunt around for it. 

 

Good shout by @0x1e, I've seen people ask about stuff like this before and be told to update their bios or reinstall windows without folk even attempting to identify the problem. 

 

Just for reference, fastboot is a UEFI option that tries to boot the OS before fully initialising all the hardware, trusting the OS to initialise hardware itself. If even a single piece of hardware has an incompatible/incorrect initialisation sequence (GPU drivers are especially bad for it), fastboot causes the exact issue you described. 

 

If a fastboot fails, restarting forces your machine to do a full boot, which would be why resetting fixes it for you.

You can disable it in windows as well.. 

I thought that you only had to do that in the bios until I was troubleshooting a computer that wouldn't go to sleep the other day and had to mess with this option.

 

going by memory here..

but hit the windows key, type power and sleep, open that menu, click "choose what the power and sleep buttons do" in the top left, click the top option in this new screen to allow you to change settings that are locked, and uncheck the first option that unlocks there to disable the windows side of fast boot.

 

I don't think that's it though.

You have a multi-monitor setup.

Could be linked to that.

Maybe try opening up your Nvidia control panel and make sure your main monitor is your primary one and all of that.

Reset everything under manage 3D settings to defaults.

Maybe do a CMOS reset as well.

 

Get back to us if it's still happening.

Disabling it in windows fixed it thanks for the help.
