    New video card, now pc won't start up
    « on: August 05, 2009, 04:48:32 PM »
    Okay now I'm kinda a real noob when it comes to computers and how they work. But so far for the 6-7 months I've had my computer (nothing fancy, just cheap at bestbuy :D) I've had 0 problems, none. Now I just bought this video card... it's called GeForce 8400 GS (I know still nothing super good but better than the current.) So yesterday I installed it and set up everything according to the disk it gave me. I was playing WoW and everything normally. When I woke up this morning I wiggled the mouse to bring my comp away from sleep mode, but nothing happened. It showed the pc was currently on, but wouldn't respond. When I  pulled the plug (wouldn't shut off otherwise) and tried to rebooting it, all that it does now is start up for about 5 seconds, nothing shows up on the screen, and then it shuts off again. It'll continue doing this forever basically without me even needing to touch anything after the first try. If any of you know how I can get my computer working again so my parents don't rip my head off, that'd be very helpful :D. Oh btw, my system currently runs 250w, and the card says it needs 300w minimum, could that be it?

    Maybe ... if you don't have enough power supplied to your computer, it simply will not boot up.

      Probably new card disabled on-board video in BIOS. Enter BIOS, and check.

        How do I do that in about 4 seconds of the computer being on? =/ Nothing shows up on my screen so I can't really enter anything that I know of.

        If you're able to, look at the bottom of the screen for something like:
        Press some key to enter setup
        Pressing "some key" will get you to BIOS.

          Unable to, the thing isn't really that the video card is messed up, it's the actual pc that doesn't stay on long enough to get to that part.

          Did you triple check, you didn't messed up some cables inside while installing/removing video card.
          Try to re-seat RAM.

            new PSU. sounds like  you might have pushed your old PSU a little too far...

              Sorry, may I ask what a PSU is? Does that stand basically for power supply?

              yes, power supply. most are designed to give out a bit more then their rating... but not for long.

              Make sure to check your +12V rails, 19A would be a safe bet, as that's what I have and I used to use a 8500GT now using a 9500gT which worked fine with that type power supply which was a Hipro at 300 watts.

                How do I check those? I bought a 450w power supply and it still does the same thing lol =(!.
