when i started my computer it went up fine :) but it didnt give any monitor signal :( . so i thought the 8 pin connector near the cpu(i dont know what that is please also tell me plz) was a power cable for the onboard grpahics. so when i plugged it in the computer didnt start but when i unplugged it it worked, but still no signal. So here is my build plz help

  1. When you've got an add on GPU like the 5770 installed the onboard graphics will be disabled.

    Ensure you have the monitor cable plugged into the 5770 and not the motherboard.
  2. The 8 pin connector near the CPU is the power for the CPU, that needs to be plugged in. Make sure you have another power cable (6 pin or 8 pin, im not sure what that card has) for the graphics card so that the dedicated card has power; the plug is on the side or back. As Rusting In Peace mentioned, make sure you have the video cable plugged into the dedicated card and not the motherboard graphics.
  3. So even if the graphics display (5770) driver is not downloaded i can still plug it in and get signal? Also when i plug power into the cpu power the power doesn't switch on. (i have 850 watt) i hear a click but when its not plugged in it starts up. So am i supposed to use the cable that came in with the power supply for the CPU or use the one that i think came with it.
    Btw when i start i here 2 beeps i think one is from the mother board and one from the optical drive which has the mother board disc in....
    I try what you guys said

  4. The driver you're talking about is for the operating system only. The card will display content on startup then when the OS starts it will use generic drivers to control the GPU. So in truth you can get away without ever installing GPU drivers however you'll want to as these drivers are far more performant and reliable than the generic OS ones.

    I can't really figure out what you are doing with cables but, for me, just do whatever makes the machine start successfully. If that means not plugging everything in then so be it.

    One beep from the motherboard is probably ok. You may want to check your motherboard manual. I don't think I've ever heard an optical drive make a beep, perhaps some clicking if it's been powered on and has a disc in the tray.
    It finally started up!

    i should of use the PSU CPU cable instead of the other one.......................................................
