Vista - Black screen during booting.

There are many problems regarding black screen on boot.
I've researched and surfed for over 4 hours, that is not an exaggeration, but found no use.

When the vista passes log-on screen then it is time ti display desktop on boot, there simply shows a black screen with mouse cursor at the center.

Task manager works, and it seems nothing is using huge system resource at that time. After few amount of time, the desktop finally appears.

I never installed driver, but in case one of them got corrupted, I installed the same version again to try to resolve the problem. It was no use.

It's a OEM version that came with my laptop and this laptop has no pirated software. Not a single one.

Why is this happening?
Can somebody help?


Vista Home Premium 32bit
2.66GHZ @ Dual 2 Core Centrino 2
4.0GB DDR3
130M GT 512MB DDR3

it may well be vista searching for another monitor although it doesnt normally take that long you can disable it see if it helps

goto task sheduler

On the left-hand side, click "Task Scheduler Local"

Expand "Task Scheduler Library," then "Microsoft," then "Windows," then click "MobilePC."

you'll see a task called "TMM." Click it, and on the right-hand side, click "Disable."

Nope. it doesn't fix the problem at all....
Anyone can help?

Boot into safe mode to see how long it takes.
This is a diagnostic test.

On safe mode, the black screen doesn't appear.
I never installed any drivers ... also tried to remove and re-installed them again.

Still no use ...

Type msconfig into the start menu.
This will give you the option of disabling startup programs and services.
go through them 1 by 1 to see which one is causing the error.
