Question PC has no video signal anymore after cleaning. (Yellow DRAM light)

[Pixcellent]

Hello everyone, I'm looking for some help regarding my computer I built, up until now it has been working great and it's less than a year old.

As the title says, after a recent cleaning it stopped sending any video signal. I also noticed a yellow Q-LED on, which my manual says is for DRAM. So I believe that means my system won't POST anymore for some reason.

I've already tried moving around the memory sticks and using just one. I also tried disconnecting the GPU, HDD, and SSD to see if any of them were the issue and I still wasn't able to get past the yellow Q-LED.

So far I'm guessing either both RAM sticks suddenly broke (which seems unlikely) or it's actually the CPU or motherboard that's busted? I would appreciate some second opinions though, as well as any advice on what else to troubleshoot before I jump to any conclusion.

Most likely related to the last thing you did. Check that all cable connections are secure - you may have bumped something in the process of cleaning.

When you cleaned the PC did you keep the fans from blowing freestyle, that is if you used high pressure air to blow it out.

I use a electric duster and I hold the fans with my hand to keep them from spinning.

Also some stuff I forgot to mention that might be relevant. I already gave all the cables a quick look/jiggle and they seemed all secure. Also all the fans and rgb leds seem to be working still (GPU, RAM, case fans, and motherboard).

I'll still double check all the connections more throughly as DaleH said though, gonna try the ol'unplug replug in a bit.

Unfortunately this doesn't seem to be the issue. I unplugged and replugged everything; and I still get no video signal along with the yellow DRAM Q-LED light.

Any other ideas?

You might need to clear the bios. Unplug from wall and than hold down the power button for 20 seconds. Than remove the motherboard battery. Leave out for 10 minutes or so.

Replace battery after the 10 minutes plug in and test.

Unless ddr4 and ddr5 is more fragile to static charge vs dd3 that could be why your yellow DRAM Q-LED light is on.

If system is still the same test the GPU in another system.

Is there anything your leaving out that you may have did when you were cleaning the PC.

It's just not you that seems to do a simple cleaning and end up here with now PC no boot.

Clearing the bios was the issue, so weird that issue comes from a simple dusting but atleast it's fixed now. Thank you for all your help!
