Windows 10: Weird pixels showing up after booting from USB

Hey! A few weeks ago I wanted to install Windows from USB but it wont work. But the only thing I see is this: Any Idea how to fix that?

:)

 

Line of pixels on startup preventing windows to boot

Yes I've tried both suggested steps. Unfortunatly the problem is still there. It doesn't happen as often as before, more like 50/50. But when the pixel line is there, my pc does not boot up anymore. First when I waited for a while, it did boot up. But
now it's just a black screen and nothing happens.

 

USB boot for bios update

Did the first step. It already doesn't work. Note the capacities and drive letters M:/N: The HP utility is about to format my raid-1 volume containing my 2 750gb drives. It thinks it's the usb stick. I can not select any other drives in the HP utility. My 512mb usb stick is U:.

Any other suggestions?

 

Help with USB Boot Image

Yes, I checked the box and showed it the folder where I unzipped the USB Image file. And then it started formatting the USB memory. Then after it completed I copied the rest of the files from the zip file over to the memory stick. Then tried to boot computer to the USB device. After restarting I press F12 to enter the boot menu and select USB Device from the list and it reads the USB memory cause the green light flashes but I get the Non-system disk error message.
