The biggest majority of the time, a crash and a funky pattern on the monitor means one of a few things is happening: Graphics card is getting too hot and is shutting down to protect itself, Graphics card driver is buggy and either updating to a new one, or reverting back to an older one will help, or the card has been overclocked and does not have enough voltage to run at those frequencies and you need to turn it down, or back to default clock speeds.
Do you have another video card you can swap it out for to see if the card is bad?
Do you have a friend that would help you out by either letting you borrow a video card to test, or that would let you test your card in their system?
I would monitor your temps and google what the temperature threshold is on that card......if it is getting warm and throttling, take the card out and blow it out with compressed air, getting the heatsink and fans. You could try and install an older driver from AMD's website as well. Also, make sure after you get the driver downloaded, before you install it, go into Control Panel > Programs and Features > Uninstall your current ATI/AMD driver for that card. Always do that when updating your drivers, get the old one off first, then install a new one.
Other than that, I really have hit a wall with suggestions......maybe someone who knows more than me will chime in with a fix. If I have a moment of clarity and think of something brilliant, I will make sure to post it here.
