Did you uninstall your old graphics drivers and install the latest driver from ATI's website for HD5770?

A good rule of thumb is to uninstall your old drivers (using the driver software like AMD Catalyst). Then run a program like Driver Sweeper to clean out any residual drivers that it may have missed. Reboot and install the new drivers. See if that works for you.

It was working ok before so...what was the previous graphics card you had installed? maybe what you thought was an upgrade, actually was not.
