DVI and Graphics card won't display anything

[alinenache358]

So, about a week ago I've been casually playing games on my PC. Suddenly, on my both monitors, over taskbar, game, windows and everything it displayed some 4x4 pixel squares, some of them weirdly having some green on it. Then, I couldn't hear anything ough my headphones, and the image changed to some yellow bars and on the other monitor a solid color. It has done this type of thing where dots will pop up on my monitors, but then it will just stop, saying that "The Graphics Card Driver Stopped but has been successfully recovered", and the only thing happening afterwards was that the transparency was gone from my taskbar, but this time nothing was happening, and then, if I tried to restart, nothing will show up, not even the BIOS pc opening screen thingy. I noticed that the PSU wasn't that good and I later changed it. And here's the weird part (I don't know if it does this because I reset the BIOS using the CMOS battery while I was trying to make my PC work with my old PCU). After I connected everything to the motherboard, checked everything at least three times, only VGA worked. (Was testing everything on the motherboard ports, with no graphics card plugged in) I also saw that the DVI won't work, and if I had both monitors plugged in, nothing will show on any of them, even on VGA. Both monitors have VGA support and both of them worked with VGA but only VGA in. If i plug in the graphics card and plug VGA in, nothing will pop up there either. I also tried with VGA and DVI both, and with only DVI, but nothing worked.

Specs:
Processor: Intel Core i5 4690
Motherboard: AsRock Fatal1ty B85
RAM: HyperX Savage (8GB Dual Channel
PSU: Corsair TX550M
Hard Drive: WD Blue 1TB
Graphics Card: MSI Radeon R9 270x 4GB

What is happening, please help.
PS: The only thing I can access the BIOS, Windows and everything is by integrated graphics, else nothing will show up.

I tried:
Resetting the BIOS using CMOS battery (I don't know if that is OK or not)
Changing the power supply (the other one was broken)
Cleaning the PC of Dust (Components and everything)
Reinstalling Windows (On VGA on integrated graphics)

I have a feeling that it's a motherboard software problem, but I'm not entirely sure.

Check your GPU in another computer, his could be a faulty GPU.

make sure the mb has the newest bios. with those cpu and mb with ipgpu when you cleared the cmos the priamny display went back to auto. set it to peg/pci and make sure muilt monitor support is on so both video cards will be on.

Well I did and it worked how it should

Are you making sure the connections are tightly connected, and that the GPU is fitting into place firmly, sometimes when you screw down the GPU to the back of the case it could also knock it lose, just make sure this isn't the case. You could also try swapping to onboard graphics, then back to your GPU and see if that solves anything. Good luck!
