parts list
I turned on but got no screen, so reset and it started fine but again, only sound on the right side. I downloaded and installed the newest audio drivers and chipset from ASRock website. Everything seemed OK (except still only sound on one side). A day or 2 later, I turned it on to finish installing the other drivers but no screen. I pushed reset and it started fine. At some point I restarted and it never came back. It was hit or miss if I could get into BIOS but now I can't get any screen at all.
A day or so later and I uninstalled everything and have it laid out on the kitchen table to run some tests and hopefully figure out the problem. The first thing I did was assemble it all like it was in the case. Same deal, no screen no BIOS but it did POST. I went ahead and switched out the GPU for a known good GT 1030 (fanless so it runs off MB power only). The only things plugged in to PSU are the CPU and MB main power. No mouse or keyboard plugged in for these tests. MB didn't come with a chassis speaker so I grabbed the one from my old computer to get beep codes.
Test 1 - no RAM, no GPU, no NVME drive resulted in no beeps and the CPU and DRAM error lights were lit.
Test 2 - single components only
- AMD Ryzen 5 3600
- ASRock B550 Phantom Gaming 4
- Corsair Vengeance LPX 16 GB (2 x 8 GB) DDR4-3200
- Samsung 970 Evo 500 GB M.2-2280 NVME
- Corsair RM (2019) 750 W 80+ Gold
- Gigabyte Radeon RX 5700 XT 8 GB GAMING OC

Test 2 - single components only
- 1 stick of RAM in slot 3 resulted in 5 quick beeps and the VGA and BOOT lights.
- NVME installed by itself resulted in no beeps and the CPU and DRAM lights were on.
- GPU only (known good GT 1030) had no beeps, CPU and DRAM lights.
- 1 stick RAM (the other one) in slot 1 and GPU resulted in no beeps and no lights.
- 1 stick RAM in slot 4 and NVME resulted in 5 quick beeps and then a single beep and no error lights.
- GPU and NVME resulted in no beeps and CPU and DRAM lights on.
