radeon hd 6770m update bluescreen problem

[Senzai]

so i went to to amd and did an autodetect so i can get the newest driver for the HD 6770m video card..once i downloaded the new driver updated and installed it, i cannot open my catalyst and says that i dont have any hardware supporting it and i also get the blue screen crashing my computer..so in order to fix this, i had to do a system restore and rollback all drivers and im currently stuck with the driver version of 8.882.2.300 which was released in the year 2011..

i have a HP Pavillion dv7 -6195us laptop 
and i ill post up my gpuz so u can help me solve my question.. thank you

I managed to install a brand new driver  (14.4) after searching for months for my 5650m!!

Go here: http://leshcatlabs.net/

14.4 1.1 worked for me!

Hi, I have a 6770m as well, and Yah, it didn't crash, it worked. I would make a restore point before it too, just in case

so i did install the update from the website, it didnt crash but it did mess up the brightness..it wont let me change the brightness settings through the function keys nor on the windows itself...any fix?>

I have a HP Dv7 6197ca with the same card as you, so here is how you should fix it: Update your BIOS to the latest version, then in the BIOS screen (Press ESC then choose Bios Setup) and change the Setting for Graphics Mode from Fixed to Dynamic. This should fix your issue. If you  can't find that option after you update the BIOS, then try the UBR tool in the UnifL Installer. I suggest trying the values F840 and F940.

If the resolution is all wonky after you switch in the BIOS, you need to re-install the drivers.

Hello Mate.

I need your help... like you, I have a Pavilion Laptop with an ATI 6770m video card.

But I did screw it the GPU Bios, so i can't use it anymore, i'm just working with the intel One.

So I want to ask you if you can send me a copy of your GPU Bios.

If yes, there are several ways, but the secure one is using GPU-Z located in this link, http://www.techpowerup.com/downloads/2360/techpowerup-gpu-z-v0-7-8/

using this tool, easily you can choose the proper GPU at the bottom of the tool window, and just in front of the bios information it collects, is the download button.

So if you please download it and share it with me, I’ll really appreciate that.

My mail is like my user at aim.com

Thanks in advance.

Best regards.
