Get a needle nose pliers straighten the pins that are bent. Make sure they are all good and straight. Unplug the monitor and the computer. Plug the video cable from the monitor into the back of the computer. (Make sure its in the correct plug this time)It should be a blue connector if it is a pc (on a mac it will be black) Plug the monitors power connector into the wall or serge protector. Plug the computer into the wall or serge protector. Turn on the monitor. It should precharge and goto sleep. Turn on the computer and the monitor should come out of sleep and be on.
If it doesn't work it could have burnt a component in the video card (if you tried to connect it with a bent pin) or the monitor. It is unlikly that this will happen. If it does I suggest heading to the goodwill to get a second hand monitor or do what davespcr said. They are relitivly cheap these days. You can pick up a CRT (picture tube) monitor from staples,office depot or even walmart for under 100$ if they stock them in your area. Be aware that some states charge a disposal fee for electronics. So be prepared to pay a ew tax.

Your monitor uses a HD-15 type cable. There should be 3 staggered rows of (5) pins each. (Some cables are missing the 4th pin in the second row, this is normal). If you used enough force, it's
possible that a pin was bent or even broken. I suggest looking at the connector (if not both) and make sure all the pins are intact and perfectly straight! If pins are badly bent or missing you should replace the cable. Next, check to see that all the monitor and power cables are fully seated, and of course, the wall outlet you are using has power. Do you know if your computer has a video card installed? If it does you may be trying the wrong monitor jack. (you'll know if there's a video card because toward the bottom of the computer, in the rear, there will be a 'horizontal' monitor jack as well as the 'vertical' jack near the serial port - make sure you're using the horizontal one if this is the case).
If this has not solved the problem, there's a good chance the monitor is no longer working and should be looked at professionally or replaced. Nowadays you can buy a very nice LCD Flat-Screen monitor for under $150, and you will be able to use it with your 'next' computer as well. Good Luck!

restart your computer repeatedly tapping the f8 key to enter safe mode while the screen is black once in safe mode where the only things working will be your keyboard and mouse allowing you to attempt to repair your computer
click start control panel administrive tools computer management device manager scroll down universal serial bus controllers you could see a yellow question / exclamation mark? ! or a red X
you will need to update/reinstall drivers
right click to reinstall drivers
if you can see your usb drive but its not working
ports(com&lpt)right click update driver if this fails to fix the problem
check the USB leads that attach to the motherboard usually red white green black make sure they are securely seated and have no dust build up on them dust will cause static and a lot of unforeseen problems for a computer and its parts
hope this helps you
