I have a laptop (ProBook 4720s) with Windows 10 that started booting to a black screen and becoming non-responsive some days ago.
When I boot, I see the HP splash screen, then the Windows logo loading and then an unresponsive black screen without a cursor.
The only way I can turn off the computer is by holding the power button.
Sometimes it'll boot to a "Windows could not start correctly"-screen and I've tried that start-up repair, which couldn't solve it, I've tried System Restore to the latest point which failed twice and I've tried booting into Safe Mode with Network possibilities and then it froze while trying to enter the password.
The only thing that worked was just booting into Safe Mode, the computer worked perfectly fine then.
I've also tried booting with a HDMI cable connected to a TV to make sure it's not just outputting the video to the wrong place, still a black screen though.
Since the laptop doesn't really "support" Windows 10 (there aren't any drivers for the laptop from the official site for Windows 10), I've downloaded some of the Drivers from [here](http://www.driverscape.com/manufacturers/hp/laptops-desktops/hp-probook-4720s/1020).
As far as I know though I think I've only installed the drivers that were necessary to make the webcam and fingerprint scanner work, though the latter still doesn't function.
Do note though that the computer worked fine after installing these drivers, it was only after a month or 2 that this suddenly happened.
Any ideas how to fix this?
Thanks in advance!
[Update]: I've started in safe mode and removed the AMD driver.
I restarted and got the same black screen, though now after a minute I got a CLOCK_WATCHDOG_TIMEOUT bluescreen.
After googling and finding that it might be related to a USB device driver not functioning correctly, I viewed the hidden devices and removed the USB drivers of the devices that weren't connected.
Now I get a MACHINE_CHECK_EXCEPTION... I don't really know where to go from here...
