Why does my PC only boot after being unplugged overnight?
PC specs:
- 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.
Ist dies eine gute Frage?

Hi @joshuar346
When you removed the RTC (cmos) coin cell battery, did you test its voltage to make sure that it is OK i.e. >2.5V DC you never said?
