  1. Did you uninstall your old graphics drivers and install the latest driver from ATI's website for HD5770?
  2. 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.
  3. i reinstalled window 7 so i got only my new grafik driver nothing else
  4. DDR3 at 533 MHZ?
    And yes, reinstall drivers. Or maybe OS if it doesn't work see here for instructions.

  5. 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.
  6. it was a ati radeon 4600 series it sucked so i dont think 5770 is worse
