Xfx radeon 5770


i have an xfx radeon 5770 running as the second card in my crossfire setup, but whenever i start up my computer it will run it's fan at 100% and not be recognized. after a few quick restarts, it works fine. i was just curious if anybody has any ideas as to why it does this. Should i exchange it for another?

  1. Make sure you have a strong psu that can handle 2 cards
  2. Apevia ATX-WA1100W Warlock 1100-Watt ATX Power Supply

    i think it can handle it
  3. i guess system specs would be in order

    intel q6700 processor
    gigabyte EP45-UD3P
    8 gigs ddr2 (2gigx4)
    crucial c33 128 gb ssd
  4. Already have the latest driver?
