    bought a new graphics card today to replace my aging 8800gt its a Powercolor Radeon HD6850 however when booting up its not getting a picture on the monitor it stays in standby..although the keyboard light comes on and dvd drive flickers so i think it is booting up..i'm not sure because i don't have a motherboard speaker so i cant hear the post beep.

    i tried 2 monitors and dvi and hdmi connectors..same problem on both monitors/cables.

    any ideas?

    You need to uninstall the Nvidia graphics drivers for the 8800gt before installing the Radeon HD6850 card. Also need to make sure a six pin power connector is plugged into the card.

    done that already mate i'm experienced with computers..i even used driver sweeper to make sure all nvdia drivers were gone and ofcourse i triple checked that the 6pin pci-e power connector is in the card.

    no but the mother board might have dust on it, if it gets in to the PCI-E slot its a chance that it wont detect your gpu

    and pulling the card out and reattaching it also helps making sure you got it full inserted

    hmm, could it be that your PSU is failing?
    or that your pci-e slot is broken?
    the card could also be defective

    does the 8800 still work when plugged in?

    if it does then i suggest RMA the new grafik card, they might have sent a defect one

    its compatible
    but the card wont run at full potential because the 1.1 has half the bandwith compared to 2.0

    if you got 1.1 then why spend 300bucks on that card?

    its probaly better to keep the 8800 and get a new mobo

    the 8800 is still one of the best cards out there
