So I decided to buy a R9 280x to replace my old graphics card. After installation I put my system back together and when I powered on the case fans lit up as well as the mobo lights. The problem is that no display comes up on my monitor and I receive no beep code feedback from the Mobo speaker. I immidiately tried swapping back out the Graphics card with my old one and the problem persisted.

I usually come lurk in these forums to solve my PC problems so, after troubleshooting some of the megathreads on TH, I came to the conclusion that my Mobo probably fried somehow. I ordered a new mobo and set my build up and same problem. So Plan #2 was that the PSU was probably giving out on me. Bought a new 750w power supply a put it in my build. Same problem again.

I really don't know what else to check. I troubleshooted the RAM but even then if that was the case I figure'd i'd atleast get a beep code, so I ruled that out. I reseated the CPU. I know that's getting power because it heats up after the power being on a few seconds. I've tried breadboarding, no luck.

Now when it does power on, all the mentioned above power on as well as all my usb peripherals except for the keyboard. I'm not sure how significant that is, but i thought i'd mention it.

My anxiety is shooting through the roof right now because, besides gaming, i need my PC for college. This graphics card replacement is turning into a whole PC upgrade and i'd appreciate any help you guys may have.

Thanks.
