Thank you both for your replies.

During the pause, bring up Task Manager and find out what processes uses
most of the CPU resources.
I can't. I press Ctrl+Shift+Esc during the pause, even several times, but it
doesn't show until the pause is ended and rest of booting process is
continued.

There are some errors at the top of the list complaining about expired SSL
certificates, but they are dated in 2059 (!)... I remember changing the date
accidentally some weeks ago, so this may explain it. Anyway, I don't think
that is part of the problem.
The only "real" error is a "NetBT" one repeated in some days ago, but not in
the last 3 days. Sorry about it being in Spanish, but you can see the event
ID, 4307. Here it is:

Are any devices malfunctioning? Select Start, All Programs, Accessories,
System Tools, System Information. Open Components under System Summary
and click on Problem Devices. Is anything listed there?
There is a RTL8168C network interface in that section, but that is because
it was disabled by me. I have a dual-NIC motherboard and since I am only
using one, I disabled the other. There are no more malfunctioning devices.
Are there any yellow question marks in Device Manager? Right click on
the My Computer icon on your Desktop and select Properties,
Hardware,Device Manager. If yes what is the Device Error code?
If I enable "Show hidden devices", I can see "parport" and "serial" with
code 24, but I guess that is normal since the parallel and serial ports are
disabled in the BIOS (the BIOS supports them, but they don't phisically exist
on this model).
This "I removed several unneeded services" may lead to problems at some
time!
I disabled some services to find out if one of them could be causing the
problem. I mean, the problem was there already before disabling them. Anyway,
I disabled really unneeded things for me, like Bluetooth, Themes, Bonjour,
and some other non-Windows services that I didn't need (EPSON monitor,
nsclient...).
Here are some other things I tried but had no success:
- sfc /scannow
- disabling wallpaper and logon sounds (I once had a similar problem with a
corrupted WAV file!)
- updating drivers: nvidia, audio, network
- flashing a new BIOS (not related but I needed to do it anyway...)
- starting computer without anything but keyboard plugged in
