Red DRAM LED Light BLINKS ONCE

iVoltage55 · Dec 30, 2013

Hey all, I have encountered a problem whist re-building my pc. I got a new case for Christmas and took all the parts and transferred to new case. When pressing the ON button, the DRAM light blinks once and the PC stays on. Fans spinning, Fan LED on, although no display

If it's an Asus board, that probably means the RAM is okay (the light stays on if it isn't).
Reseat any / all connectors. Make sure the CPU power cable is plugged in. Did you mount the motherboard on standoffs OR raised bumps molded into the case (but not both), and only put a standoff where there is a mounting hole?

Onus :

Yes, it is an ASUS board. And I mounted via standoffs

Well then, perhaps reseating will help. Also make sure the front panel reset switch isn't shorted.

If it worked before it is probably something you simply overlooked. This list is for new builds, but it can't hurt to go over the steps to verify you got everything!

Onus :

I have reseated multiple times.I will try front panel reset switch.

Still, not working

What MB model, CPU, GPU, PS, do you have? DO all the other three LED post lights come on and then off. Each of the four lights is supposed to come on until the CPU, GPU RAM and HD is detected and then they go off. DO you have another PS? DO you have a volt/ohm meter. Can you check the CPU and GPU six pin plugs ( if you need them ) to verify 12 volts on the appropriate pins. Have you tried an alternate input on your monitor? HDMI, DVI or VGA?

Mine flashes red once on startup too, not sure what to do about it - I think I've been having some stability issues with mine (undervolted it by accident) resulting in occasional freezing. However i usually works just fine. I've just reseated mine and corrected the voltage, hopefully its all gravy. The PC is stable most of the time.

Anyone know what to do about the red dram_led flash?

Just fixed issue when powering on machine that would blink once dram led and then not power on at all by pressing the CPU 8-pin cable so that it would click.
