Recent experience: I assembled my own system and got it running. Updated drivers for GPU and motherboard, used the machine briefly then powered it down. The next morning it started up and operated for about 90 minutes, crashing three times. On the third incident, the PC failed to power on completely; the DRAM LED illuminated and remains solid orange.
I attempted:
- Reconnecting and disconnecting components in the case (PSU, GPU cables, fans, RGB, RAM).
- Reseating CPU, adjusting cooler, removing PSU, taking out CMOS battery, holding power button ~30 seconds.
- Testing RAM one at a time, moving it closer to the CPU, which caused crashes after ~2 minutes.
- Checking fan operation in both A2 and B2 slots; fans worked but RGB stayed off.
- Noticing DRAM light activation in both cases during boot.
Notes: All components were new and unused. Initially, RGB lights activated with fans on simultaneously. After a minute of normal boot, fans started before lights, then the PC stayed on without shutting down. It no longer powers off when the power button is pressed; it only cuts off after a long press, but RGB stays lit. When powering up, CPU LED flashed briefly before fading to DRAM LED. At first, one fan side shut after ~60 seconds, but later both fans and RGB came back on after a minute.
This issue persisted beyond 15 minutes of continuous operation. The DRAM indicator stayed illuminated in both cases.
Have you refreshed your profile info? It seems you can't start at all now? You're even worse off than before? Did any recent changes make things worse? If you manage to boot, have you turned on Expo? If yes, attempt a clean install. It's possible the issue isn't with the BIOS but with something else. You might want to reset the BIOS yourself. Simply remove the motherboard from the case using just cardboard and minimal hardware.
