HP Pavilion g7-2302ev ( in need of a custom bios)

[Penkata]

I would like some help with my laptop.The GPU is nearly dead. The AMD GPU is capable of displaying a stable image for 5 to 20 minutes. As I don't need it, a friend told me that I could install custom bios that allows me to disable the GPU for the most part and use only the Intel HD Graphics provided with my i7.

Main Specs:
Intel Core i7-3632QM
AMD Radeon HD 7670M (1 GB DDR3 dedicated)
I have 10 GB DDR3 installed ( I did that)
128GB SSD with caddy
1TB Hard drive

Thanks in advance!
