There is a sporadic boot problem involving a DRAM LED.
There is a sporadic boot problem involving a DRAM LED.
No need to worry about when the issue arises. When I power it on, the POST begins and the CPU light flashes briefly before the system stays on the DRAM indicator until I power it off again. I’ve observed that the rear intake and bottom fan eventually cease rotation after a few minutes of gradual throttling, while the top two front fans continue to operate normally.
And that is the order of events involving two motherboards and two PSUs – correct?
But in general, the system will eventually (occasionally) start up.
Uncertain about the fan setup – how are the fans physically linked?
Check the CPU/ fan headers and the connections on the motherboard manual.
Which fans are attached to which headers?
Are there any splitters or adapters involved?
The main aim is to identify a shared reason behind the boot failures.
Just considering it – someone might point out a potential problem or concern.
Yes, the same problem occurs with two mobos, two power supplies, and two RAM sets. All fans are connected via Sys_fan headers, the CPU cooler to cpu_fan header, and the radiator fans to a PWM controller linked to the pump. No splitters are used; everything is plugged directly into the board. I also checked Windows last night and saw that fast startup was enabled. Is this the same as fast boot in BIOS? I’ve noticed some complaints about fast startup—could it be the cause?
From my system using PowerShell:
The current power schemes are listed, including Active, Balanced, Dell, High performance, and Power saver.
High Performance matches the Control Panel settings.

Updates may cause issues and can be unstable.
Review the update history for failed installations.
Consider switching power plans temporarily to rule out Fast Startup as a cause.
