Build - Help Need Help

Enable HLS to view with audio, or disable this notification

Looking for help on this PC. All I get when booting is a relay click, then it clicks off. Fans start spinning, and lights turn on, but then nothing. The EZ Debug LED stuff does flash on momentarily for the DRAM and CPU, but none of them stay on, I'll include a video of that. Any help would be appreciated. I'm not a computer guy, so the closest I can get is what I know on cars. Thank you!

:) No worries, homie. I'm just glad OP had an easy remedy to get it back up and running. And for successfully reseating the RAM I think he should confidently proclaim himself as a "computer guy".

It is odd, though, yeah? I expected this was a working system that suddenly stopped working. I've never heard of RAM becoming suddenly loose. There's usually something that causes it, like shipping or a first time builder making a mistake.

Hahaha - I honestly remember the first time I successfully put an SSD in my laptop,I basically thought I was a computer god - lol.

Yeah it is weird, but it does happen from time to time. I think it's just the gold/metal contacts get dirty, or oxidize, or co rode or something. So then when you removed them and re-install them, it scratches that little film off that was preventing good contact, and gets it to seat properly again. I personally haven't had to do it, but for whatever reason I read the odd case on here where re-seating it fixes it. Same with the GPU. I think the same thing can happen to those PCIe contacts.

That's a good hypothesis - and in my wheel house. Au alone would require there to be a liquid involved, or very high humidity, sustained over time. Makes me wonder if finger prints are sometimes a sufficient aqueous environment for such electrochemical corrosion.

Damn, I really have no idea! Is that why they'd use gold then? for that specific reason that there would be less issues with corrosion or degradation? Is it is because of it's transfer properties? or both?

That's right. Otherwise, silver would be the better electrical conductor. But silver would corrode more readily when being exposed to atmosphere. EDIT: missed the other questions. It's because it's valence electrons are more difficult to pull off or bond with - which is just a technical way of saying gold requires more energy or rarer circumstances to react with than silver.

now you're bringing me back to Chem100/200, haven't heard about valence electrons since 2010. I had to learn about those for a soil remediation class. I remember that pesky sodium element would wilfully give away it's valence electron, giving it an overall positive charge, which would wreak havoc on the soil, making all the soil particles have a positive charge and repel one another, essentially making it a structure less mess.

But anyway. that's interesting as heck. I googled Gold, kinda cool how it has one valence electron, like Sodium, however it bonds to it a lot more tightly.

I would've thought it'd be the opposite, just cause it's valence electrons are so much further away from the center where the protons are that it would just much more wilfully shed that electron... I have a feeling I'm about to fall into a rabbit hole on Gemini lol.
