PC No Display AKA Black Screen

[BlackScreenProb]

Hello HP,

my gaming PC is facing some issues. For one, I can't get it to display anything or POST. The PC was fine until a couple days ago when it started crashing a few times (static noise then black screen). The PC is an Envy h8-1549.

Parts:

Mobo: Pegatron (?)

PSU: 750W EVGA Supernova NEX750B

SSD: Samsung Evo 8 250 GB

HDD: WD Blue 1 TB

CPU: i7 3770k

GPU: Gigabyte R9 390 WindForce 8 GB DDR5

RAM: 2x 8 GB 1866 MHz Corsair Vengeance Pro Series + 8 GB 1600 MHz G.Skill + 8 GB Micron MT16JTF1G64AZ-1G6E1

I have tried resetting the CMOS to no avail. I unseated & reseated everything except the PSU and CPU, and swapped RAM around a little bit. I could probably get my hands on another PSU to test it out. My screen's main input has always been DisplayPort, but I can also do HDMI. Unfortunately the mobo only has DVI-I (Dual Link) output, for which I don't have a cable. But I do have a DVI 24+1 to HMDI adapter.


Thank you HP, I'm really in the dark here.
