My build:
3rd gen i7-3770
Gigabyte z77-Ud3h
Nvidia 650Ti
16gb ripjaw ram
WD 1TB 7200
240gb chronos ssd
cosair 600w

Scenario:
I bought all the part above off newegg. Assembled the computer works fine. Installed windows 7 via a clean boot off a thumbdrive. Computer works great! ... until i plug the nvidia gpu into the 6 pin psu cable. Computer boots with gpu attached to mobo (but not connected via the 6 pin from the psu), but the gpu fan just goes crazy. When i try to boot with the 6 pin plugged in the system boots, i can hear the window sound starting and everything but there is no display on my monitor.

What ive tried:
-disabling the internal gpu (on the BIOS and the Control Panel) but this result in no display on my monitor what so ever.
-switch the graphic boot to pci (havent tried peg) but it just goes back to auto
-pluging the monitor cord (vga) in to the mobo vga and the gpu using the DVI connector that came w/ the gpu. both result in no display on the monitor
-downloading the the driver off nvidia (with the card plugged in to the 6 pin after boot up) but the download fails because it cant detect the gpu supported by the driver
-unplugging and replugging everything into the mobo
-computer work fine as long as the gpu isnt plugged into the 6 pin psu cable

As of now i cant use my nvidia gpu which really sucks. need help please:/
 
Solution
Using the GPU, you must plug your monitor into the GPU. and you must have the 6 pin power connector plugged in.

Does your monitor have a DVI port? If so plug it into there.

I tried booting the computer with the gpu plugged into the 6 pin PSU cord. My monitor only has a VGA output but the gpu came to with a VGA to DVI adaptor so I can plug my VGA cord into the gpu. The monitor is connected to the gpu and the gpu is plugged into the mobo and the PSU, but still nothing on the screen. I can't even get to the bios screen. I don't think it's a power supply issue bc 600w should be enough. Is there anything I can do in the bios? I tried door sing driver for the gpu but it doesn't detect the hardware so the download fails.

My mother boards is reading an A9 error (won't post) only when the gpu is plugged into the 6pin. Idk if that information would help solve the problem.

Thank you for the quick responses! Any further advice is greatly appreciated.
