I have built several computers in the past and this build is the first to have ever given me any kind of grief... https://pcpartpicker.com/list/dPvW9G
for parts list.
- When booting with both my monitors, PC starts, fans run, power LED is on, but no graphics are sent. I don't think it even goes post-Post, since pressing the power button to restart does nothing. The only way I can get out of this situation is to switch the power supply off
- When booting with my main monitor (32" Samsung S32D850 at 1440), same exact situation
- When booting with my secondary monitor (24" LG 24GM77 at 1080), the PC boots fine
I've tried pretty much everything, and this is the only situation I can get it to boot: with my secondary, vertical monitor. I then plug my main monitor after I hit the Bios screen and it's fine from there.
PSU is a Corsair AX850 which worked perfectly in my previous build and has plenty sufficient power.
All drivers are up to date; Windows update, BIOS, graphics. The Device Manager doesn't show any unknown devices. Once booted, I plug my other monitors and everything works just fine.
I also tried the same exact setup down to the cable with my old GTX970, and it worked/booted just fine with either/both monitors. Only the 5700 shows these symptoms. No post, no boot.
Nothing is plugged into the monitors; no USB stick, peripherals etc... That's about the only tip I found for similar-ish situations I found while looking for my symptoms.
Thanks for any tips on how to fix this! This is my first AMD build and it's had nothing but trouble getting started, so I'd love to get it running and for it to maybe change my mind.
