Windows 7 - Blank screen after booting if turn on computer with power button

OS : Win 7 Ultimate SP 1

Problem :
I can not log on windows with power button.
So, for the detail :
1. When i turn on my PC (use power button)
2. It's on then go to dual boot menu then I press enter on
windows 7
3. Then, the normal boot appear (windows logo with "starting
windows" text)
4. After that, the screen goes blank, just black screen
without cursor

my vga and ram is ok, I already use the latest driver for my
vga card

I can start my win xp normally (my dual boot is win 7 and
win xp)

I can start my win 7 with safe mode and low resolution

I also can start my win 7 normally after I force restart my
PC with reset button

Any help would be appreciate

sorry for my bad English, I'm Indonesian

Try disabling the display adapter in safe mode.
Safe Mode
Why is my screen black when I start Windows 7?

@theog : do you mean disable via device manager in safe mode ?
Sorry for long reply

GOD BLESS US

@theog : Yup, Thank you it worked for me, I disable my graphic adapter from device manager and my pc can run without restart if I want logon to my win 7, thank you for the advice. By the way, how to fix my problem, I mean I need my graphic card, then if I enable it again my pc can not logon to my win 7 without restart it (back to my primary problem).

Are you sure you downloading the right display adapter drivers?

@ theog : yup, i download it from asus (my vga asus EAH4650/DI/512MD2) global website, is it okay right when I download my driver from global website ? (I mean not download it from region or country website of manufacture)

@ writhziden : thank you for the advice and reply, yup OK, Thank you ^^

If you are sure, you are downloading the right drivers, you may have a overheated display adapter, Try changing to the onboard.
