Question could my motherboard burn out my gpu

[ibrahimvr1]

I upgraded my cpu and mother and ram last week and yesterday i was just browsing and my system shut down when i tried to turn it on pc led will turn on and the system shut down again so thought it maybe some heat problem soi checked if all the psu cable connected and i tried again to turn it on after 30 mins but the same thing light on and shut down without any post and at the point i start smelling some burn but for some reason at the time i thought its good idea to try again so i can see the debug led but my gpu started shooting sparks so i unplugged the pc
i did build more than one pc but its my first time to upgrade one so i am not sure what did go wrong
mostly think its the psu is problem but i want to be sure since i am going to buy new graphic card and psu at same i hope nothing go wrong

Sounds like PSU to me. Good luck
