Solved Laptop display turns off at welcome screen.

[Imrankhan]

I own a HP pavilion g6 2132tx. For last 2 days, my laptop screen turned off on reaching welcome screen. So I decided to clean install Windows 7 again, Since I thought its because of virus problem and Avg and Norton didn't detect anything. After clean install formatted my whole hdd after backup. I am installing drivers and restarting after each driver. After installing Amd driver from hp, the same problem occurred again. So I went into safe mode and uninstalled amd driver. My laptop became normal. I also tried with latest driver from amd, Problem occurred again.

My laptop spec:
i3 processor
4gb ram
amd Radeon 7670m + intel hd 3000
Now Intel Hd 3000 driver is installed any my laptop is working fine. It shows Standard VGA Adapter in device manager since no driver is installed for ATI Radeon graphics.

Please help me.

It could be possible that your AMD Radeon HD 7670m is failing because it has got physical problems (the card is faulty).

Also when I download amd autodetect tool, it said unable to detect.
If this is a physical problem, is there a way to change mobile graphics with a same one. I heard that graphic card cannot be replaced.
I am out of warranty, I have to fix this myself or use my lappy without amd graphics without Aero themes.

You can't replace the HD 7670m because it is part of your laptop's motherboard, so you should replace the motherboard.

However, you can use your notebbok only with Intel HD 3000 Graphics, which provides smooth desktop features and it is capable of HD videos.
Also it supports Aero themes, so you will be able to use your pc normally but with less performance in 3D games or apps.

Simply go in control panel/device manager, disable the Radeon HD 7670m GPU and keep running only Intel HD 3000 Graphics.
