ok so i upgraded from a 9600gt to a gtx 460, i put the new card in and connected it to the psu , i still have only the 450 watt psu but it says thats the minumum so i expected it to at least start, although it doesnt even register with my monitor,so i put back in my 9600 gt and uninstalled the drivers i had for it cause i was told to try that by a friend,but its jsut the same thing, my monitor jsut goes into stand by cause it doesnt even register its connected, its not the monitor because it works fine with my 9600gt and i use the same DVI lead, so do you think theres a problem with the card or its just the psu, (i am upgrading it just not for a while)
