Ok, so I've seen some forum posts with similar problems but none seem to help. So, I recently bought a new CPU, Motherboard, and GPU.

Specs:
GPU: EVGA Nvidia GTX 650ti
CPU: Intel Core i5-3570 @ 3.4ghz
MOBO: ASRock Z77 Extreme4
PSU: HP 450w
HDD: Hitachi HDS721010CLA632 ATA
OS: Windows 7 Home Premium
Monitor: Acer X191W (VGA)

I also have another GPU (GT 530) in my pc, because whenever I plug in the 6-pin cable from my PSU to my New GPU (GTX 650ti) the onboard graphics to my motherboard seize to work. Like its nonexistent, and then my GPU (GTX 650ti) will not display the boot screens.

So I need the other GPU to investigate the problem, and then (miraculously) I got it to be recognized by windows, but then the other GPU (GT 530) took over, reinstalled, and then deinstalled the GTX 650ti, then I tried turning off the PC, take out the GT 530, remove the 6-pin power cable from the GTX 650ti, and then plug my VGA cable into the onboard graphics, and now it wont recognize the GTX 650ti, even though the correct drivers are installed.

I'm honestly so confused at this point... It's either the Onboard Graphics thats taking over and not letting the GPU work, or the PSU. But I don't understand how the GPU is working (fan spinning) and seems to be fully powered and it not work. So the only way I got it to recognize is when the other GPU is plugged in with it, but obviously its going to continue to deinstall and reinstall and fight over each other.

Any suggestions are helpful.

Try this go into your CMOS battery setting or BIOS setting and there should be something like that "init Display First" set it to pci-e. It should either be in CMOS battery setting or BIOS settings.

New Cpu, mobo, and GPU, right? I assume this means you had to install a new OS due to the new mobo. If so did you partitionthe windows boot off your hard drive ( I am assuming you are reusing the same HDD or SSD.

This could explain why your PC is recognizing the 530 especially if you used that GPU on the build the HDD/SSD came from.

I am suggesting that in case the BIOs set fix does not work.

Yeah I totally forgot to take that into consideration.
