  1. Try re installing your old card and see if your PC boot or not if he dose it mean your new card has a problem.
  2. What's your power supply? Could be demanding too much power so as soon as it gets called upon for more resources to show you the windows screen blah blah it's sucking too much power.
  3. i have a 600 w, and the old card boots fine, the total my machine could pull is under 600w, so i should be good, i see a lot of other people having the same issue though
  4. Total wattage is not whats important, that is just a general guide. It is how many amps your psu can supply on the 12 volt rails when you need to really get down to whether or not your psu has enough power. A 600 watt quality unit usually does it. An inferior or cheaply made unit might not supply enough clean, steady amps.
  5. plus the gpu wont draw more than 50 w on boot!

    it wouldnt use that much power in the start anyways. if it had too little power, it would shut off, or reboot. not get stuck at post.
  7. Okay. If you say so. Newly released hardware can be buggy for early adopters. Could be a bad card, but I dont think so in this case.
