Hello everyone, here is my build and I will now proceed to ask a couple questions: https://pcpartpicker.com/list/bsB3D8

1. So I finished building my PC, double checked and everything is where it should be, and whenever I try to use both the GPU's and the MOBO's HDMI ports my screen will stay black and won't give any signal, at first I thought it could be my mobo's bios needing an update, and took the PC to a shop, when they were updating the bios they noticed that only the DVI port would give signal to the screens, so my question is, could this be a driver issue that once I install them my HDMI ports will be fully working or is there something wrong with my mobo? Worth noting I live in a 3rd world hellhole where finding a DVI-D adapter is difficult but I would like some input regarding my issues before proceeding

2. Back when I was building my PC I had to unscrew the front metal plate from my r9 280 so it would fit inside the case, and while I was doing that there was a small spark in the place where I was unscrewing one of the screws, below one of the DVI ports in the front plate, could that have been static electricity? and if so, what are the odds that broke my GPU? The fans still spin and it seems to work normally but that's been concerning me.

Thank you to all of those that offer their advices/input.
 
Solution
get into BIOS and set IGPU Multi-Monitor to enabled.
so onboard graphics and dedicated video card will work simoultaniously

hdmi should work out of the box (if the 280 is not installed in the motherboard)

latest intel graphics and amd drivers installed?

BIOS version is now on 7.0?

in the FAQ of this board was mentioned for the onboard graphics:
Please set "Package C State Support" to "Auto" in the BIOS.
(BIOS -> Advanced -> CPU Configuration -> Set "Package C State Support" to "Auto")

the spark could have broken the video card

1. I have the necessary pins. 2x 6+2 are just as good as 8 pins as indicated by literally any source on PCs I've seen, as well with my PSU being able to handle it because the total wattage output of my build is around 420W if I remember correctly, many people who have 500W PSUs even use 280x's given the other components do not use too much power

2. Of course I never handled any of my components with the power on or while plugged in, to call that moronic would be a huge understatement, that happened when the GPU was not attached to the MOBO or connected to the PSU, while it was on top of my case.

Thank you. Your suggestions were spot-on and I did everything you recommended and I got my system up and running, however you were sadly right about my GPU, the PC won't even recognize it's plugged in despite that the fans are spinning and everything, am I completely screwed or is there anything that I could do?
 
try the card in another system

if it´s broke, you would have to replace the damaged components on the card, analyzing and soldering. That´s not a job for someone who doesn´t know the schematics and without test equipment it´s nearly impossible to repair it.

Besides that, it´s possible the 280 won´t boot because of insufficient power or a fault in the power supply. Try a better power supply if you can. 500W are fine, if the PSU is a good one. This Thermaltake is made of low quality.
