Dear Dell,

I've bought a new Inspiron N5537 Intel Core i7, 8GB, Intel HD and AMD Radeon 8850M, 8G DDR3 then installed Windows 7 x64.

I installed Intel GPU first, then AMD GPU with drivers downloaded from Dell website, using Photoshop CS6, try to edit a simple photo , then, the laptop crashes with the blue screen several times.

I tried to removed the AMD driver, downloaded the beta driver from AMD website, installed, opened PS6, still, nothing worked. It keeps crashing, even when I didn't launch any programs,I have to use system restore to reverted to the time Intel GPU installed (without AMD's ). It crashes with the blue screen again.

Then, I installed AMD driver from Dell again, still, it crashes. 

What should I do now?
