So I built a Ryzen 7 1700x system paired with an EVGA GTX 1070 SC Black Edition a few months back as an upgrade from an old FX6300 rig I used to use to play my HTC Vive. Well, I had everything running just fine on the new machine for a month or so without issue and was able to enjoy my HTC Vive using a Displayport to HDMI adapter for video output to my TV and the HTC Vive's HDMI in the dedicated HDMI output on my GTX 1070. I wound up having to work virtually nonstop for about two weeks and never really was able to use the new rig until I downloaded Fallout 4 VR recently. I waited the 4 hours for the game to download and then went to play it, only to find out that i couldn't seem to get the PC to boot properly while the displayport was plugged in. It would show the Motherboard logo and all that but when it went to boot into windows it would go black and then my TV would pop up saying there was no input detected. I've spent a month now on and off trying to fix this issue so I can use my Vive, but NOTHING seems to work.
Things to note:
I get a signal when I manage to boot into Safe Mode.
I've scanned countless times for any viruses or other malware and get nothing.
Everything works fine through HDMI and the DVI outputs.
I'm only trying to use the single TV NOT a multi-display settup.
BIOS has since been updated already.
Exact setup worked previously with use on displayport.
Hardware:
CPU: Ryzen 7 1700x
Motherboard: MSI x370 Gaming Pro Carbon AC
GPU: EVGA GTX 1070 SC Black Edition
Cooler: EVGA CLC 280mm AIO
Boot Drive: 128GB Toshiba OCZ RD400 Series M.2(RVD400-M22280-128GB)
Storage Drive: Seagate 3TB BarraCuda HDD (ST3000DM008)
Power Supply: EVGA 750W 80+ Gold
RAM: 16GB TridentZ 3000MHz RGB (2 x 8GB)
TV: LG49UH6090 (2016)
Things I've Tried:
I've tried re-seating my 1070.
I've tried unplugging the power cords to my TV and PC.
I've tried various drivers from both Nvidia and the windows 10 updater. With and without using DDU.
I've tried setting the power management options to all prefer maximum performance.
I've tried countless Cables, both new and the ones that were working fine before.
I even tried to contact Microsoft tech support(non scammers) and was basically told they didn't know what was wrong and that many hardware issues are known on windows 10 version 1709 and that I should try reverting to a previous version, which I was then told that I couldn't do since it was installed with that version.
I'm more or less all out of options and am now looking for help! I just need more options to try because I've now tried the listed options probably like 10+ times on each. I personally believe its some conflict between windows 10 and my TV seeing as the most noticeable variable between the new rig and old rig was the OS.
