Help me please.

So awhile back i built a kaveri computer with the a10 7850k, and recently i decided to upgrade and get a discreet graphics card, and r9 270x. It worked for a couple days, then one day, the computer screen wouldnt even boot and my keyboard and mouse wouldnt light up to indicate it had power. The computer would work just fine if i unplugged my graphics card and removed it from the pci slot, but it doesnt work when i try to use it. I went to my friends house to test the graphics card and psu that i recently got, and they both worked just fine. So i suspected it to be a motherboard problem. I replaced the motherboard, and still the same problem. Now when i unplug the 270x and try to use integrated gfx, it doesnt work and the mouse and kb doesnt even light up either. When I switched back to my old motherboard, i couldnt even use the integrated graphics card. The mouse and keyboard didnt light up either, and I tried multiple times. PLEASE HELP ME FIND A SOLUTION :c

Did you install the drivers?

what's your PSU? Could be a power issue?

Sounds like it's eating up a whole ton of power. How many watts is your PSU, and how many amps are on the 12V rail?

psu is an antec vp550f and it should be plenty. it doesnt even work anymore with my integrated graphics. my keyboard and mouse and monitor doesnt even power on, i switched back to my old setup and still nothing worked.
