I'm kinda freaking out cause I just spent $500 on a new power supply , Graphics card, and ram. I put it all together, started it up and it made a crackling noise and I smelled smoke so I switched it off and unplugged everything. I could see smoke (glass side panal) pouring out the graphics card so hope the mother board is fine. Really my question is why did this happen, I don't know computers and honestly I didn't check to see if the power supply was compatible cause I thought they were all the same (also completely possible that ive put in together wrong haha) but I know the graphics card and ram match. Any help is appreciated, Thanks
