I have laptop with 2 GPU, one of them has been dead.

I have laptop:
-chipset AMD 880G or 785GX ?)
-mobility radeon HD4200 and HD5650

The last one is dead. I have turned-off it in device manager via safe-mode, and now I can boot my OC (W7).

Problem: 1) HDMI output doesn't work 2) VGA-out refresh rate 85Hz max

Solution 1: replace broken gpu and don't use different series gpus in crossfire.
