    Upgraded my GPU now my computer won't start
    « on: January 18, 2011, 10:56:26 PM »
    I tried to upgrade my gpu but I was stupid and didn't bother unplugging my computer or turning my psu off first and I didn't uninstall any of the hardware or drivers ahead of time. Now when I turn my computer on my screen just stays black. The fans all spin and the lights come on but that's it. I tried to reinstall my old gpu and it did the same thing. Then I tried to reset my bios, used different power cables, and switched pci-e slots but still no change. Did I just wreck my computer??? Help:(

    When booting, does your monitor have power?

    Did you properly connect the cable from your monitor to your VGA card?

      Are you saying that the computer was on when you installed the card?

        Not "on", but there was power going to the motherboard.
        I know, it was a retarded mistake. I guess that's what I get for trying to install hardware while sleep deprived...

          UPDATE: I just tried to boot my computer with no gpu installed and there were no error beeps. Does that mean my motherboard isn't working right?

              I attached my speaker but it still doesn't beep when I remove the RAM or gpu.

                What model is your GPU? Does it require an extra power cable from the PSU, and is that plugged in?

                  It's a Radeon HD 3870x2, so yeah, it takes two power cords. I've tried starting my computer without the gpu installed and it still does the same thing though(restarts after a couple of seconds of startup, no us devices turn on, ...etc.)

                  Congrats.
                  You've either fried the MBoard and/or the vid card.
