good day friends from bleepingcomputer.com, i come to this forum to ask for assistance on my apu desktop. i have recently installed a gpu "hd 6450" on my apu desktop, installed a program to check my gpu info "cpu-z" and reconfigured my bios to allow me to perform a hybrid crossfire. after my reconfiguration on the bios my apu desktop booted and continued to perform well just untill it was stuck on a black screen and a white cursor. i have read many threads about this black screen and knew that this is maybe due to just 2 causes, either hardware issue or software issue.
i ask for your assistance in pointing where the problem could have started. i cannot pinpoint if my issue is wether hardware or software.
btw, i had this error message showing after my apu desktop tried to perform a disk scan "replacing invalid security id with default security id for file #####" and it started from 1 up to 100,000.
tried startup repair - failed
tried system restore - failed
