Radeon HD6850, Hazro HZ27WC LED Problems

[ddmphoto]

I have disabled the on-board graphics card and have installed the Radeon HD 6850 Graphics card to use with my Hazro HZ27WC monitor, but i am getting intermittent interference on the screen.

The interferance is at its worst during start up then starts to settle down after the system is fully running, but it flickers every now and again with streaking lines across the screen.

my system details are as follows:

I am running Windows 7
System Model Packard Bell ixtreme M3720
System Type x64-based PC
Processor Intel(R) Core(TM)2 Quad CPU Q8300 @ 2.50GHz, 2499 Mhz, 4 Core(s), 4 Logical Processor(s)
BIOS Version/Date AMI P01-A3, 21/07/2009

What do i need to do to get it working

Have you installed the graphics driver for the Radeon HD 6850 graphics card? Go to this website http://support.amd.com/us/gpudownload/Pages/index.aspx and select the graphics card that you own and then download the appropriate driver for it to your desktop or anywhere and install it and reboot after completion and hopefully, this will solve the interference on the screen.
