Hi all 
Since I've installed my new graphics card I've had quite a lot of random system crashes/freezes.
This happens a lot when I'm downloading or updating things especially on Origin or trying to play games, But sometimes nothing is even running!
When I start a game the screen turns grey and green & Purple colours flash at top of screen for about half a second
before the game starts and when I shut them down same thing happens!
But they usually just crash after a few mins of play (Need to reset PC).
I have all the latest drivers installed for the card and my motherboard plus it has the latest bio's installed.
I only changed the graphics card, everything else remains the same,
And I used amdcleanuputility to get rid of the old drivers before installing the new ones.
Another thing my bio's screen doesn't show up properly anymore big black blocks appear across the screen, I'm using a HDMI port on a lcd TV.
Anyone got any idea's
