Black screen with "loading cursor" and no login screen on Boot.
Hello everyone,
First of all, I will divide my statement by sections so it would be easier to read.
Section 1: The problem - description of it.
Section 2: How I manage the problem.
Section 3: Things and methods that I have tried - all unsuccessfully.
Section 4: My own findings to help with further analysis.
So here we go
Section 1
Whenever I start windows it will boot normally up until Windows logo screen(where 4 balls meet to form windows 7 logo) at this logo screen I can already notice slow pace as it stays in it for a good minute. Afterwards it will be just black screen for a minute. Then mouse cursor will appear(with faster sensitivity than my usual) and it will transform into a loading wheel cursor after another minute. And now it reached state in which it can stay for hours. Only black screen and loading mouse wheel(note that it is always spinning and I can always move it, it is not frozen).
Section 2
So the only way for me to login is to leave it be for at least about 5 hours and it will start itself. Usually I do this overnight and in the morning it is already at the desktop and works like nothing ever happened. I can do whatever then, everything will work perfectly fine. Crysys 3 works fine, YouTube works fine - no trace of any problem. So while I can always just Hibernate and sleep my PC, I need to restart it sometimes.
EDIT: Now after those 5 hours or more, it will simply display ordinary mouse pointer on a black screen and act as if I am in login screen. For example it will sleep after 30mins of no movement and instantly wake up on activity.
Section 3
So far I have tried those methods:
1. Clean boot
2. All of F8 advanced boot options. (Only safe mode and repair windows work)
3. sfc /scannow in Safe Mode.
4. Uninstalling video card driver and reinstalling with the latest compatible.
5. CCleaner while in normal mode.
6. Other anti virus and malware softwares.
7. Windows restore (no back up point).
8. Deleting network drivers.
9. Reinstalling them.
10. Disabling all network related devices in the Device Manager.
Section 4
While Fail Safe mode works neatly. Fail safe mode with networking support loads but freezes after about 30 seconds. And won't unfreeze, only mouse will be movable, but everything will be irresponsive and will give me errors like shown on the post 10 here, below in the replies.
It appears to be happened after I downloaded windows update for Virtual machine support. During the update I went away from my laptop(when I left it was restarting itself to apply updates) and when I came back 1 hour later I found my laptop on the same black screen with loading mouse cursor. I waited 20 minutes more and forcefully restarted it. And it was black screen again. Since then I have uninstalled everything regarding that update and virtual machine through programs and features in the windows updates tab.
There were few times when I saw a BSOD after black screen stood for about 2 hours. But was unable to read them fast enough.
Sometimes the laptop monitor will change its brightness during black screen.
The laptop will restart itself after about 1 hour of black screen and go into it again.

EDITs: Sorry for the edits guys, I am using Android to write this and I want my post to look both informative and easy to read.

I usually solve problems like this myself through hardcore researching and analysis, but I fail on this one.
Thank you everyone who will try to help and suggest anything.
Thank you for your time,
