Why does my SCREEN go black after the Windows screen logo appears when I boot?
and when i try to log in using safe mode, it works fine in safe mode and i have tried to adjust using safe mode.
Right click on the desktop and click Properties, and then on the Settings tab.

Now click and drag the Screen Resolution slider to the FAR LEFT ... you want the smallest settings that your screen will support. Typically that'll be 640x480, or 800x600.

Also change the Color Quality dropdown to 256 colors, or whatever is LOWEST. (You probably don't NEED to go as low as 16 colors, if that's presented as an option.)
click ok then i reboot it but still the problem is not solved?
please help me, i have tried this for 2 weeks, but still the problem is there?
thanksMain suspect would be your video card.
When you boot to Safe Mode, your video card driver are NOT loaded, Windows uses its generic VGA driver.
Do you have separate video card, or it's on-board?
Try to update your video drivers, first.
If that doesn't work, borrow video card from a friend, and se, if it works.
