I might've bricked my computer. Send help.

So I decided to install some fans and clean up a bit with some dust cleaner inside my pc. Everything was working fine prior to me doing this. I also did some cable management and connect two extra fans one to the HAMP fan connector and another to the CPU fan. I have a H100i connected to the CPU Opt header. So there's that and also I ended up connecting the graphics card cables on the wrong ends. I wasn't paying attention and didn't connect back the 2 8 pin connectors and end up connecting 1 8 pin and since one 6pin into the perif1 in the PSU. The only other thing I did was change the direction of some fans. This is what I am using.

i7-7700k
Asus Z270e Mobo
1080Ti FE
2 8gb Corsair Vengeance Ram
750 Nova PSU
2 Samsung Evo SSDs
Corsair H100i v2 AIO
Asia Blu Ray Drive.

When I tried turning it on after all that I heard a spark noise couldn't tell from where though. So I quickly turned it off. After that fixed the GPU connectors. It turned on for a while but turned off after maybe 30 seconds and restarted by itself. I didn't notice at first but my keyboard and mouse didn't light up and no signal was being passed to my monitor. So after that I removed the gpu and turned it on and it stayed on but I wasn't getting anything on my monitor by the hdmi on the I/O. Next thing I I did was connect the gpu back and it stayed on but I was getting no signal still and keyboard and mouse were still not lighting up. So my question is did I just brick my motherboard or my graphics card or (please please please no) both? I know this is long. I appreciate any help I can get. I'm going to try to get a DVI cable tommorrow and see if I can get a picture on my monitor but my keyboard and mouse aren't turning on even tho the Mobo power leds are turning on. I just hope its not worst case scenario.

I am a bit confused exactly what got connected to where? The fans that you added shouldn't matter. The incorrect plugging-in of the GPU might be bad.

So you connected one of the GPU 8-pins to an 8-pin VGA power and the other 8-pin to a 6-pin PERIF1 power. That PERIF1 is for 4-pin peripherals and does not supply the same voltages / amperages.

I am not certain if that would damage the GPU, it doesn't sound too good. You may have to test the components separately to know which is hooped.

So the cable I used the to the GPU we're 8pins but on the other side they have a 6pin+2pin. So I had forgotten which way they went and plugged them in backwards and instead of plugging in the 8pin sides into vga1 and vga2 I plugged in 1 8pin into vga 1 and the other which had the 6pin+2pin into perif1 since that's the only place it fit. I just left the 2pin hanging. Which is what I did when I built the computer the first time but it was the other way around so the hanging 2pin would be going out and so therefore I would have the 8pin ends connected to the gpu. The psu is more than enough to handle everything. I really don't understand what went wrong. Worst case is both my mobo and gpu are dead. Would this be under warranty for repair at least in anyone's experience?

Couldn't say, you would have to get in contact with the manufacturer.

I would try tearing the system down completely and starting from scratch but based on your story and symptoms I would suspect that there is some type of hardware damage.

Individual component testing would likely be required.

It's hard to tell as your explanation of events is still a bit unclear to me. But if you did manage to put the wrong end into the PSU and GPU, it's quite possible the GPU is fried. If you're worried about the motherboard, you should be testing it with the GPU completely removed and the monitor plugged into the motherboard to see if it works with the GPU removed from the equation.

Don't tell the truth to the motherboard / gpu for your warranty.

A simple, "it stopped working" should work.

We're telling people to commit fraud as advice now?

Well he is more like telling half the truth xd but yes it is wrong.

A lie of omission about a material fact that he is aware of isn't a half-truth. In law, it's what's called "silent fraud." If the OP's ethics don't bother him since it's unlikely he'll be caught, that's his business, but it sure as hell shouldn't be actual advice we're providing here.
