I'm using Windows 10 v1709, i5 6600k and GTX 660. All drivers are updated and Windows is up-to-date.

So basically, clicking restart or when Windows crashes (talking about in-game crashes when it stutters for a second, then freezes for ~5 seconds and then just reboots, no BSOD or any message), takes longer than two minutes to reboot. My OS is on a new SSD. Shutting down the computer and then immediately powering it on takes ~12 seconds.

In those two minutes, it goes to the Windows logo in the same amount of time, and then just keeps spinning on the logo (powering off my peripherals in the meantime, a couple of times) and then finally arrives at the login screen.

The shutdown-and-power-on scenario is relatively quick because Fast Startup is enabled by default:

How Fast Startup Works

Fast Startup combines elements of a cold shutdown and the hibernate feature. When you shut down your computer with Fast Startup enabled, Windows closes all applications and logs off all users, just as in a normal cold shutdown. At this point, Windows is in a state very similar to when it’s freshly booted up: No users have logged in and started programs, but the Windows kernel is loaded and the system session is running. Windows then alerts device drivers that support it to prepare for hibernation, saves the current system state to the hibernation file, and turns off the computer.

When you start the computer again, Windows does not have to reload the kernel, drivers, and system state individually. Instead, it just refreshes your RAM with the loaded image from the hibernation file and delivers you to the login screen. This technique can shave considerable time off your start up.

As a result, your shutdown-and-power-on procedure will typically be much faster than a reboot (which isn't affected by Fast Startup).

You can see the difference first-hand by temporarily disabling Fast Startup and then timing a few shutdown-and-power-on cycles for comparison.
