So i have a windows 10 acer aspire desktop for months now with no real problems. But now after an update it just starts into a black screen before login. The mouse shows when i move it but dissapears after a second and then it will always go back to the center of the screen. Ive tried logging in blind but it did nothing. Ive tried shutting off the computer during startup to enter repair mode but nothing. Ive tried alt f10 to factory reset but it says the pc needs to repair and gives an error code 0xc000000f. Any help is appreciated.
