So I've tried SEVERAL different threads' solutions and haven't been able to get anything to work. The issue I'm having is strange, though, because of the lack of common factors.

First off, I bought a new graphics card, an ASUS nVidia GTX 760, and it's the second graphics processor this computer has, the original being an AMD Kaveri 7860k APU.

So I plug it in, only to find out that my case is too shallow to fit it. So I remove the screws holding it into the case, lay the case on its side, and plug the card in. Side note: I forgot to plug it in to the power supply at first.

I start up the computer, and it immediately shuts off. Confused, I turn it back on again. This is when all hell breaks loose. A loud CRACK, a spark from the opposite end of the motherboard (right between the keyboard/mouse ports (which I never use) and the mobo's built in monitor port, and I smell gunpowder. Reminded me of the cap guns kids play with. Smelled just like that. Anyways. I panic, and turn EVERYTHING off. After a few seconds of collecting myself, I turn it back on. No crack, no smoke, but no display. I can't see anything on my screen. Now I realize that the new graphics card isn't plugged in to the PSU, so I plug it in.

Still nothing. I try connecting an HDMI directly to the new card, maybe it has to use the new gpu's ports. Nothing. So I figure I must've fried my motherboard. SUcks, but fortunately, I still have my old motherboard, along with the Richland 6800k APU that it had. So I pull everything out, and put the old MOBO in. Everything is connected, including the new nVidia, and I turn it on. The EXACT SAME THING is happening.

I try everything I tried on the old motherboard. Nothing. Everything gives me the same results. Computer is on, fans are running, no display. Side note: The USB mouse lights up, but the USB keyboard is unresponsive, even when switching between USB ports.

I remove the nVidia. Still the exact same problem.

The ONLY common factors in this situation are the case, the PSU (which is a brand new 750w Rosewill, and is not the problem), and the RAM. I've used two different mobo's, each with their own APU, with and without the nVidia, and I can't get my computer back up and running. I'm at a dead end, and the only solution I can think of is that somehow that pop (which was far from the RAM slots, too) fried both of my RAM sticks.

I don't know what to do at this point, and I'm very frustrated. Can anyone give me some advice? I don't want to go out and buy new RAM, just to find out that it's not the RAM, but I don't see what else could possibly be wrong.

It's defiantly not your RAM's problem. Although I would really upgrade it if I were you. That ram just ain't gonna cut it with more demanding games. And I feel like its most possibly your PSU's problem because you said it's brand new. Either that or the card just doesn't like APUs. Another possibility is that your hard drive/ssd corrupted during the first boot up so now it doesn't recognize anything. My suggestion is to take it to a IT specialist and ask them because I don't know your situation and cannot see your computer so I have no clue what other problems there might be. It would be the wisest choice to bring it to someone who can physically see and tinker with your pc to get it working again. Good Luck!

Thanks for the advice guys. I actually fixed it by putting in a THIRD (my first) motherboard. So, to summarize:

3 Motherboards.

1: Fried from the spark
2: Just randomly dead. Possibly the APU.
3: Much older board, but still compatible with my nVidia. Works just fine with RAM as well.

Problem was two separate mobo issues that just happened to present in the same way. Have tested all aspects with this new card, all RAM shows, the nVidia is running at full capacity (just scored a 7.9 in both graphics and gaming graphics in the windows index!) and everything is up to par. Thanks for the help, and I hope my solution helps others who may have similar issues.
