Specs:
GPU: Sapphire radeon r7 260x
Motherboard: ASRock 960gm/U3S3 FX
CPU: AMD FX-4130
RAM: DDR3 8GB
And a 600 watt power supply
Windows 7 64bit

So I ordered a Video card a sapphire radeon r7 260x

And in my computer theres a onboard video card a ATI radeon 3000.

I disabled and removed the ATI radeon 3000 drivers. and installed the Sapphire radeon r7 260x drivers like a million times but I can't get it to work I only get a black screen when I connect the sapphire r7.

I also put in a sapphire radeon HD 3870 and I un-installed AMD catalyst and installed it again and the radeon HD 3870 worked fine,

So I put in the Sapphire Radeon r7 260x back in and did the same thing uninstall and install.
But still no signal.

And now I'm at a point that i uninstalled something from AMD and now when I try to uninstall AMD catalyst trough ''Control Panel\All Control Panel Items\Programs and Features'' It says ''Error applying transforms. verify that the specified transform paths are valid.''

Why are computers so freaking complicated??! Every time I change something to my computer it goes wrong, every d@mn time.

I already did this of course. I already put the power connection in the gpu and it was connected good. :/
