r9 270x problems( sapphire toxic edition)

[bxstatic]

mobo: M5a99x r2.0
psu: corsair tx-650
gpu: sapphire r9-270x toxic edition
cpu:amd fx-8320
ram:gskill sniper 1866 (2x4gb)

whats up guys, i've just run into a problem while installing my new gpu, btw i upgraded from nvidia 7900gs to the r9 270x. I installed the hardware and then installed the amd software, then uninstalled the nvidia software. When i thought everything was done, when i tried to play games like BF bad company 2, the game attempts to start and i guess it crashes in the process with no error messages or anything. If you guys could give me some insight as to what the problem might be that would be great,

yeah..this is software related error..

actually you can install amd driver along with nvdia driver without any issue..

so, try to clean any nvdia related driver with driver sweeper..(http://www.guru3d.com/content_page/guru3d_driver_sweeper.html)

and install your amd driver once more again..

it should fix the problem..
