Tech Studs,
I could really use some advice. While I was gaming with a seemingly normal PC, my screen flickered twice and died. Mouse and keyboard lost power too. Both of my monitors couldn’t detect my computer. After all of my troubleshooting, monitors will still detect that they are plugged in but will not display anything from the computer. All of my RGB and fans are still powered, motherboard debugger isn’t calling out anything.
Troubleshooting I’ve done so far:
- Unplugged computer and held down power button to clear voltage
- Reseated RAM sticks
- Attempted to reflash BIOS (did not register USB)
- Tested voltages of 24 and 12 pin PSU mobo connectors with a multimeter
- Replaced the mobo completely and replugged PSU cables
- Attempted boot with CPU uninstalled, still did not post
- Attempted boot with each RAM stick in DIMM A1 to see if it was a bad RAM stick in new mobo
- Boot with monitor plugged into mobo vice the GPU
I’m pretty much at a loss with where to go here. I’ve followed a lot of troubleshooting guides and I keep hitting dead ends. I thought for sure it would be the mobo, but the new one is also not talking to the peripherals. I really do not want to replace every component 1x1 until it works but that’s maybe where I’m at right now, any help is appreciated to turn my light-up box back into a computer!
Current build:
- CPU: Ryzen 3600XT
- GPU: Sapphire Pulse RX 5700 XT
- Memory: 4x Ballistix 8gb DDR4 3600
- Mobo: MSI B550 Mag Mortar MAX Wifi
- PSU: EVGA 850 G5
- Storage: Boot Drive is an M.2 NVMe Inland Premium 1Tb

Bit of a doozy… I’m not sure what to suggest, but how did you try reflashing the BIOS if your monitors were on but not displaying anything lol? Maybe I just misunderstood.
This seems like something you should go to a technician IRL about, considering how much testing and tinkering you’ve tried with no results
RESOLVED Keeping up in case someone else has similar issues with their peripherals. Computer booted perfectly after replacing the CPU. Initially replaced the mobo as part of troubleshooting, so I can’t isolate that it was just the CPU that was bad. Also, learned that you cannot access BIOS unless you have a working CPU installed to process the software built into the mobo. Lastly, buying a single stick of cheap RAM was a great way to verify my 4 sticks of RAM weren’t the issue. A stick of truth, if you will.
