try to reinstall your windows, it is like your windows have some problem

Something is having a problem loading. Usually these are drivers or the last program installed.

When you boot start pressing F8 as soon as you see something. This is before the windows screen so you have to power on and start pressing F8. Then select Safemode. This will boot up windows without loading any drivers. Once you are in safemode then you can go to control panel and uninstall the last thing you installed. sometimes just booting into safe mode and then shutting down and rebooting normally will clear the error.

Having said that this can also be casued by a virus that has damaged windows files. You can repair your windows setup if you have the windows cd. If you have to use the system restore it may allow you to repair or attempt to but usally will try to wipe out everything and set it back to factory.

From your brief description, it seems that your hardware is starting correctly, and then it tries to load Windows. Windows then fails to load fully, and so Windows forces the computer to restart.

So, turn the computer on.
Immediately press F8 (again and again) until a "start-up" menu is displayed. Select "Safe Mode" and see if Windows will start.

If it does, use the "System Restore" application within "System Tools" within "Accessories" to go "back-in-time" to a date/time when your computer *was* working correctly. Restore to that date/time.

check your RAM and hard drive to make sure they are still inplace. they may have been damaged when you dropped it

try turning off screen saver gl

There is a program that is failing to shut down in general, which is delaying the computers ability to shut down.
The next time you shut down, make sure you have no programs open. Then, while attempting to shut down, wait until Windows pops up window asking you to close a non-responsive program. When it does, take note of the program that it mentions, then close it and see if Windows shuts down. Note: sometimes this takes a really long time.
Try re-installing the non-responsive program and see if your computer can shut down normally again.

I had the same problem, I went to the keyboard and shut down the beep there is a check mark next to it and take the check mark off, the beep will stop

You should go to the BIOS and load the default settings. Also, check your device manager to check if all hardware is installed and functioning properly (no conflicts, etc).

start up windows in safe mode and see if you still get the problem. did you use the same vga cable???
