How to find out why windows 10 takes so long to load?
Asus N56JR laptop (i7 4700HQ4 cores, 8GB RAM 1600, nvideo video card)
Initially it was win 8.1, then it was updated to 10, a year later it crashed (bootloader).
Recovery did not help, I had to reinstall ..
After reinstalling, it loaded for 10 seconds .. on the next. Day decided to reboot and this problem was found.
These are definitely not viruses, it is installed cleanly and no, this is not an update installation.
In safe mode , it also loads slowly, mostly hangs at the "welcome" stage. Sometimes when just the Windows logo and the bootloader circle at the bottom (Moves, but takes about 5 minutes or more).
Reinstalled several times, the situation repeats ...
update, update, after 2 reboots this story begins.
Microsoft is silent, Google did not help, you are the only hope.
The funny thing is that on win7 it loads in 4 seconds, there is no such situation.
Still, it seems that this is because of the drivers or the cache ..
But I don’t know how to check, maybe there is some kind of debugger that writes who hangs there ..?
Yes, after fully loaded there are no problems. But when the bootloader crashed, the same situation occurred when loading .. Right now, I decided to start it with debugging in safe mode with 8 cores (4 cores, 8 sweats) and max. memory .. still hangs. Turned off debugging too. What is in normal startup mode, what is in diagnostic. There is no difference at all. Someone writes that in laptops the bus is limited so that it does not get warm .. Maybe this is the case?

Answer 1

what is it because of the drivers

So install the drivers from the ASUS website for Windows 10. Remove unnecessary devices, remove unnecessary drivers (there is an article on habrahabr.ru).

Какой ноут? Модель?
