".it stopped working after I unplugged it when my computer hang..."

The next time that happens, hold the power button in or down for at least 4 seconds until the mboard shuts off, or remove the AC power to the computer, when the computer hangs, to minimize the possibilty data on the external drive could be damaged.

External hard and optical drives require that the USB port(s) they are connected to can supply 500ma (1/2 amp) of current.

If the external drive is plugged into a USB port it can actually work with properly, you probably damaged data on the drive yourself by NOT using Safely Remove Hardware to STOP accessing it when you unplugged it while Windows was running. In most cases you can use certain programs to repair the data damage and have access to your data again.

Troubleshooting USB device problems including for flash drives, external drives, memory cards.
See Response 1:

...."now everytime I plug it in...its either my computer shuts down and reboots ...."

That has probably got nothing to do with the external hard drive.

Windows is set by default to automatically Restart when it encounters a fatal error - an error it can't recover from.

Press F8 repeatedly while booting, don't hold down the key, and when the Windows loading choices menu appears, choose
Disable automatic restart.......

When you see a blue screen with a message on it
- quote the STOP: 0Xx0000xx error (we don't need the stuff in brackets beside it)
- if there is a problem file named, tell us what it is.
- if the text mentions it made a mini dump file, that can be analyzed..

On some computers, they have a different use for the F8 key while booting, e.g you'll see a menu of devices to boot the computer from.
If you see that, read the text on the screen, press the key that exits that menu, then immediately press F8 repeatedly to get the Windows loading choices menu.

Connect the drive before starting the computer. If the computer boots into Windows then go to Windows Disk Management to see if the drive is listed there. You may have corrupted the file system on it.

If it is listed, highlight the drive listing and then post everything stated about it.

thanks for the immediate reply, I'll try what you've said and reply what happens

that's another problem, I tried connecting the drive before the computer starts, now after the windows loading screen it only shows a black screen..if I remove the hard drive it immediately shows up the cursor and shows up the login screen.....

Did you connect the drive to a FRONT USB port? I ask because the front ports are connected to a header on the motherboard. If the wiring is connected wrong there is no problem until you connect a device to that port/s. The result can be a fried device or a fried USB controller.

This same condition can happen with rear USB ports that are not directly integrated onto the motherboard.

If you had/have the problem OtheHill mentions in response 4, assuming you haven't fiddled with wiring for USB ports since you had problems with this external hard drive, you would have had problems when the drive is plugged into the same USB ports previously. If anything else works fine when plugged into the same wired USB port, there's nothing wrong with that wiring, other than it may not be good enough to handle the 500ma the external drive the external drive requires from the connection. .

Having the wiring from front USB ports or from an adapter plate with two or more USB ports on it installed in a slot space at the back of the case connected to the wrong pins on a USB header probably at worst causes the external drive you plugged in to not work.
However, some mboards, e.g. some Asus ones, have double row headers for two USB ports AND one or more headers for (a) firewire port(s) that have identical headers - 9 pins, 5 on one side, 4 on the other, one pin is missing in the same corner position. The plastic at the base of the header for the two uses is usually colored differently, but sometimes people connect the USB port (or firewire port) wiring to the wrong header.
You have no problem when nothing is plugged into the USB port that is wired to the firewire header , but when you DO plug in something into the mis-wired port, all hexx breaks loose ! You usually immediately get an error message from the mboard's bios, and the cricuits for the device you plugged in and the circuits for the firewire port and possibly other circuits on the mboard will be damaged in a short time if the USB plug is plugged in for too long.
