HP G62-455TX Graphic Card malfunctioning

[Rock997]

Problem is the laptop screen flickered and went off several times, displaying error message that AMD crashed. I reinstalled the drivers replacing the older with the older version and then with the latest version given on the website.
But in both cases, the laptop screen totally went blank not even showing the BIOS screen. I connected it to the external monitor to get the output. It shows a bluescreen dead screen and restarts. However, it boots up on the safe mode (but on a external monitor).

However, The laptop screen is off blank throughout.

I tried booting it up with Linux-Fedora 20 XFCE, but it gave error in loading Radeon graphic card, and it did not even boot up.

The laptop has the following specs:-

Hi @Rock997 ,

Welcome to the HP Forums!

I would like to take a moment and thank you for using the forum, it is a great place to find answers. For you to have the best experience in the HP forum, I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.

I see that the display flickered several times and then displayed a black or blank screen.  You connected an external monitor and on startup a blue screen displays and restarts.

You tried booting into Safe mode but nothing displays on the external monitor.  Notebook display remains blank.

You tried booting with LInux but it also gave the graphic card error.

Here is a link to Troubleshooting Black Screen Displays with No Error Messages During Startup or Boot to assist you.

Here is the HP G62 Notebook PC Maintenance and Service Guide.  You will notice there is no recommended replacement graphic cards.

You would need to replace the motherboard or system board.

I hope this helps.
