After i install the driver and restart my computer windows is loading but at the logon screen the screen goes black and shows a message that says unsupported input

The OS-loading screen is a stong indicator that thee is nothing wrog with your hardware, but it is a driver issue. You need to press F8 as your computer starts up and enter SAFE-MODE.
Windows 7
Using the F8 Method:

1. Restart your computer.
2. When the computer starts you will see your computer's hardware being listed. When you see this information start to gently tap the F8 key on your keyboard repeatedly until you are presented with the Windows 7 Advanced Boot Options screen as shown in the image below.

3. Using the arrow keys, select the Safe Mode option you want.
4. Then press the enter key on your keyboard to boot into Windows 7 Safe Mode.
5. When Windows starts you will be at a typical logon screen. Logon to your computer and Windows 7 will enter Safe mode.
6. Do whatever tasks you require, and when you are done, reboot to go back into normal mode.

In safe-mode remove & delete the drivers you installed. If you can, revert to your old driver set.

if the message you recieve is no input signal if only means that you have a problem with your video card, the monitor is fine but you need to have your video card check

Get a new OS Installer, I suggest you take Windows 7

Press F8 continuously while starting the computer. When black screen appears eventually (right before Windows loads), choose Last Known Good Configuration.

This has happened because of a Microsoft update:

In Safe mode (F8 at boot up)
Start-search for cmd
With search result -cmd- right click choose option Run as Administrator
type in- net user administrator/ active:yes
type- exit
restart- pc logon screen should show administrator account
if you can logon through this account, alter any accounts you want through control panel

Are you able to go windows safe mode if yes ... Start > Run > Msconfig > Ok

in the general tab you have option to seleect Normal Start up > Click on apply and ok and restart yiur computer that should work

From what you say, I'll assume you see stuff on the monitor like the BIOS info,and the Windows splash screen. Then it goes black.
This happens when Windows loads the video drivers for your video card. Up until that point, you are using generic VGA drivers. I would guess the drivers are corrupt and the video card just stops working when it tries to access them.
You'll need new drivers for your card (you'll need to determine that--you can ask me directly by clicking on my name if you need help there). Then you'll need to start your computer in safe mode and remove the video card from the device manager. Depending on the directions you have for your video card, you may have to tell the computer not to install drivers when you restart your computer, but run the install program first.

your windows prolly crashed because your hard drive is going bad, and thats why your getting error messages when reinstalling.

Did you install some program lately?
If yes,

1.- Start up your computer and before windows start hit F8
2.- You will see a black screen with many options
3.- Select "Safe Mode"
4.- After Windows loaded up, uninstall the last programs.
5.- Restart in normal mode
