I put my USB in with my windows 10 in and the USB stick lit up. So I thought my USB ports worked because of that but my mouse and keyboard don’t turn on when I plug them in. Also when I plug in my monitor to my pc nothing shows up.

Here are my parts: CPU - AMD Ryzen 5 1600

Motherboard - ASRock B450M-HDV

RAM - G.Skill Aegis 16 GB

Hard drive - Seagate Barracuda 2 TB

Graphics Card - XFX Radeon RX 580 8 GB

Case - Corsair 200R mid tower case

Power supply - EVGA BR 600 W 80 + Bronze ATX

Thank you in advance for the help.

  • Intel i5-13400F
  • Gigabyte B760M DS3H DDR5
  • Kingston Fury Beast RGB DDR5 16GB 5600
  • ASUS Dual RTX 4060
  • Gigabyte P650G 650W Gold PSU

Since almost brand new, the PC has had an intermittent issue: after power outages or sudden power loss, it stops posting and shows the DRAM debug LED on the motherboard. When this happens, the RAM RGB does not turn on at all. Sometimes it can recover after clearing CMOS or reseating components, but most of the time it only works again after being fully disconnected/disassembled for several hours or overnight.

Already tested:

  • CMOS battery removal/reset
  • full power discharge
  • RAM reseated in different slots
  • minimal hardware configuration
  • full disassembly/reassembly

Debug LEDs cycle through CPU/VGA/DRAM and usually end stuck on DRAM. The issue has progressively worsened over time.
