  1. For an LCD monitor, set the refresh rate to 60.

    Also make sure your power supply can run the video card a 5450 should not use much power at all, but if you have a weak or cheap power supply, can bring it over the limit.

    Also, is that a new or used card? If used, it could have been damaged already. I've run into used video cards that don't work when the drivers are installed but work on the VGA drivers.
  2. my card is new i have a power suply of 600W i tried to download new drivers from amd but when i instal them my scren goes on and off when i turn on my computer i can work on ih like for 30second and it frezes
  3. Try a different card, if it's new should be covered. Also make sure the PCIe slot is not a 1.0 rev, and the video card is not 2.1, some 2.1 cards crash or don't work on 1.0 PCIe slots.

    Can try a BIOS upgrade for the motherboard also.
