Windows 10: PC suddenly got very slow overnight

Basically I turned my PC on and the boot time suddenly got significantly slower. Not only that but opening programs on it takes a while too. And of course it interferes with gaming performance giving it more stutters and that is not ideal at all lol. It happened the day after I shutdown my PC using the timed shutdown command on cmd shutdown -s -t . Boot times take about a minute and a half now which normally takes less than 20 secs before. Same with shutdown speed which is significantly slower as well.Here's the list of things I've done to try to fix it: System file checker sfc /scanno

PC suddenly became dangerously slow!

I don't have enough time to analyze the boot trace now, but at first glance your problem is related to your second disk (HDD).

Does your HDD contains systems files? When you unplug it does your system boot correctly ?

I'll look indepth to the boot trace this evening;
