Really BIG GPU Problem.

First off, let's start with specs.

AMD A6-5400K Dual-Core 3.6GHz (3.8GHz Turbo) Socket FM2 Desktop APU with DirectX 11 Graphic AMD Radeon HD 7540D

Now, the problem... I started it up, installed an OS and continued. Got all the drivers, and the AMD GPU integrated with the CPU burned out and now only supports VGA graphics adapter... As I install the AMD Driver, it displays absolutely NOTHING after the Windows Boot Screen and before the logon screen. So, I went out, bought a NVidia graphics card. Here is the card.

Now, I stick it in. I go into the BIOS and switch integrated graphics to PCI-E Graphics, and it runs.. After the POST and the BIOS, it freezes in the middle of booting up on the Windows Logo. It freezes my display, and no log on sound occurs. Now if I try to reinstall windows, the same thing occurs. It freezes on the Windows Logo.

Now the funny thing is, I switch back to Intergrated Graphics in the BIOS, and the computer SOMETIMES freezes my screen and reboot while the graphics card is plugged in. When the graphics card is plugged out, it will never freeze.

]The computer shut down on me once, I couldn't turn it back on. I had to pull the PSU plug out from back and plug it back in.

So there is my story.. Hope if anyone can help me..

Hopefully, that poor quality PSU didn't damage the PC. Did that come with the PC? Was the PC a prebuilt?
