So, this is really bothering me. I am using windows 10 and When I boot up my computer and don't press ctrl alt del when the "enter bios" part comes, my computer will boot normally, but when on the logging screen, Im getting insane white flashing screen and cannot absolutely do anything. This is a gif of what happens: https://gyazo.com/1a8d852b1315e677c383aef1516a6057

But when I press ctrl alt del on boot up, my computer works normally, what the hell? I have a clean install of windows 10, because I had similar problems on the last windows, when I just upgraded to a new gpu, gtx 1060.

Need help!

Fast boot up doesn't work aswell. when I did a clean install of windows the fast boot up was automaticly on, so when I turned on the computer without pressing ctrl alt del, I didnt get the white flashing screen, but I got random black screen blinks and super laggy computer, and by normally restarting it, the computer worked fine again. but when I turned it off and back on, even with the fast boot up it does this bs

where did you get windows from?

you have 6 other threads on this issue and one specific thing caught my eye where u mention "watch dog key"----this links to a key generator or virus.

The watch dog thing is a scan by avg antivirus, and I do not get that scan anymore. I had a genuine windows 7, after that I did the free upgrade to windows 10, and a month after that I did a windows 10 clean install from the recovery tab menu. I have a genuine windows 10 which is activated. No viruses whatsoever.
