Solved Laptop and Dead GPU

[Montmorency]

Hi.
I have a HP G62 laptop with a ATI HD5470 and Intel's iGPU.
The dedicated ATI died and my screen is always black (everything else works and I can boot and blindly type my password and hear Windows starting).
Using safe mode (where Intel's GPU work by default) it's impossible to install/access AMD's drivers/Catalyst center; this poses a problem because I can't switch to Intel's iGPU (it's done in the Catalyst interface).
If I completely uninstall AMD's driver in Device Manager and reboot the computer works because it doesn't see AMD's driver and so uses the integrated Intel's but... immediately after boot Windows starts to install AMD's driver and the screen goes black again. This happens without internet connection, so the driver is somewhere in the PC.
In the BIOS there's no video card options.

How can I impede Windows from installing AMD's drive?

Can you access bios and disable ATI gfx or switch to select iGPU first on boot ?? not sure how many options you would get on a HP bios screen

Thanks for the link, but the problem is not the uninstall but Windows installing it again right after reboot.

There are no options at all in the BIOS related to GPUs.
HP BIOS is so basic it makes you wanna cry. It is also the latest version.

Yes I understand that but if all traces of the Driver are removed that should not happen ...

yeap, that makes sense. I'll give it a go and post back.

It didn't work, after reboot Windows started to install the drivers even without internet connection.
I'm giving up, been with this for the last two days. I'll use an older machine until buying a new one.
Thanks for the help .

Do not give up just yet .... Go to the Device Manager select the Graphics Card that has the Issue ...

Does it state Standard VGA ? ... If not right click and select Property's / Drivers Tab which Version is Installed ? ...


Also if you know the full Model Number of your Laptop could you please Post that ?

The card states ATI Mobility Radeon HD 5470
The driver is 8.741.1.1000
The laptop is HP G62 b10sp

nope, the card is dead.
I went through the uninstall utility again... safe mode, run the tool, reboot and... "Windows failed to install device drive..."
So the bloody AMD driver wasn't there, I installed the Intel one and run Windows update: I looked for the inevitable Radeon HD update and hide it, run the other updates, reboot and things are working fine.

Thanks again for your good will.
