Windows 7 startup problem

I've been facing this problem ever since i formatted my computer,, at first it loads normally, then just after the windows starts up (right before the Welcome screen), the screen goes black, the computer lights stay on, as if the computer is running normally, but the screen stays black,, i tried to install the graphics driver, i've also tried formatting the computer a few times and changing from x64bit to x32bit,, but no good,, there are 3 ways i use to make the computer work fine:
1) Safe mode
2) running on low resolution mode
3) Restart on command (restarting the computer instead of shutting it down, or pressing F8 and then pressing Alt + Ctrl + Del)

So can anyone please help?.......
