You are very welcome bulldog43!

I seem to having some problems locating your product.  Could you verify that product number for me again?  Also, what is the model name of the notebook?  Having both pieces of information will allow me to locate it based on one or the other.

Hello bulldog43.

I would like you boot into Safe Mode and attempt to reinstall your video card driver.  You're currently unable to boot into regular Windows.  So, you'll need to make sure to boot into "Safe Mode with Networking" in order to download the driver.
This Microsoft article covers how to boot your computer into safe mode.  Once you're booted into Safe Mode you'll need to visit this site and select your operating system.  Once you have your operating system selected you can choose "Driver - Graphics" to locate your video card driver.  Once you installed reboot the notebook and verify whether the issue has been resolved.

I will await the result.  I hope you enjoy your evening!

Hi there,

I have tried through locating the right driver eventually after 3 attemps of trying, because first 2 attempts to install was failed, anyway I found right driver at the end I think because this time it didnt fail to install, then after rebooting while it is in safe mode unfortunately still didnt work, same thing again, windows is loading but still in black screen, I can only hear sounds of it. I dont know what else I can do, hoping your helps,

thanks,

Hello bulldog43.

Which version of Windows are you running?  

If the graphics driver didn't fix the issue I feel that next you should look into the system files.  Windows is telling you that it needs a repair in order to start so it is possible that a necessary system file is damaged or corrupted.  The command you will use is called System File Checker and will have to be used from the command prompt.  Try the following.  

1. Boot your notebook back into Safe Mode.
2. Click Start, type "cmd.exe," and press Enter.
3. type "sfc /scannow" and press Enter.  This will begin the system file check.
4. Allow this to run.  It may take a little time.
5. After the process is complete note any results and post them here.
6. Reboot and verify whether the issue is still present.

Hi there,

I have just done exactly in safe mode using these prompts, and  I had a message saying " Windows resource protection did not find any integrity violations."

Then I booted up and nothing has changed, still I got the black screen coming out and I only hear windows starting,

and I got windows 7 pro operating system

Good afternoon bulldog43.

I believe you may be experiencing a problem with your graphics card.  It could be failing or maybe the cable for your LCD screen is loose.  You should try to hard reset the notebook.  This forces the notebook to reinitialize the hardware and can solve a lot of issues.  Here are the steps.

1. Power down the notebook.  
2. Remove battery and AC power.
3. Press and hold the power button for 15-20 seconds three times.
4. Replace battery and AC power.
5. Boot notebook and verify whether the issue was resolved.

Do you have an external monitor?  If you are able to connect to an external monitor and see a picture it implies the graphics card isn't (completely) dead.  If you can hook it up to one let me know the result as this will be very important information.

Would you be comfortable opening up your notebook to check the monitor cable?  If so, I am more than happy to provide that information for you.

I will await your reply.  I hope you continue to have a good day 🙂

Hi there,

I just tried taking battery and AC Power off and on again with the instructions, but nothing changed and I noticed windows is loading more slower than before, but still black screen anyway,

I got a CRT monitor and a laptop which I am contacting you with, are these any good and how do I connect my notebook to any of these,  with usb cables or what else,

And just wondered, would it still works in Safe Mode, if anything is wrong with video card, and loose LCD Cable

Thanks again,

If you're looking at your notebook's LCD monitor there should be a VGA port on the left side between the HDMI and the vent.  This should allow you to connect it to your external CRT monitor.  I would suggest connecting the monitor before turning on the notebook.  Then power up the notebook with the lid up and monitor connected.  If you don't get a picture after a few minutes try closing the lid.

Let me know how it goes.
