Cant run gtx 660 on HP envy 700-239

I bought a HP envy 700-239 PC and tried to change the GT 635 card it comes with for my GTX 660 and the 440 watt PSU it came with for my 625 Watt PSU, the PSU worked fine but then I try to put the GTX 660 in the PC wont turn on at all.

  1. Did you put the 660 fully into the pcie slot and lock it in? Did you attach the power supply cables to it?

    Yes, I did both of those but it still wont power on.
  3. Do you have a lot of experience upgrading PC's?
    Were you careful to de-static yourself and werent yknow... Licking the motherboard? :D
    Are you 100% certain you have connected up all the required cables.

    If you've done all the above...
    And you tested the 625w PSU with the old graphics card and it worked... and you swapped graphics cards and now the PC wont turn on...


    Sadly, if it's all connected up right, seems like you've somehow brick'd [destroyed] the motherboard or the PSU...


    Time to bite the bullet and:
    - try with the old graphics card again...
    If it works, you know its the graphics card. [if not, it's LIKELY the psu. But could actually [unlikely] be the motherboard, or processor.


    Ah the wonderful world of PC repair that is purely, process-of-elimination.

    When I put the old card in it works fine, also the computer is Windows 8.1 if that means anything.
  5. Then return the 660 to get it repaired or replaced.
