Older gaming pc stopped working. Bios code help.

[Jstagzsr]

I built my son a gaming pc out of parts I had laying around in boxes trying to get him into the pc world.. he loves pc gaming but he uses a usb controller on PC. I failed as a pc master race gaming parent ..

 

So he started his pc like normal one time, everything was fine.. he opened fortnite and the screen went black. After a few minutes I held down the power button till it reset. When turning it back on the bios post beep occurred but then the screen stayed black. The bios opening logos didn't even come on screen.  And the tv doesn't even recognize anything is plugged in.. so today I pulled the computer apart trying to fix it.  Disassembled and reassembled everything.  Hit the power button.. still nothing.. but now I noticed the post code of "d5".. so I looked it up and have no idea what it means. Never heard that before..

 

Any help would be greatly appreciated.

Probably dirty memory or slots, clean it up first with an iso alcohol.

Try 1 stick first.

The reason I took everything apart and put it back together was to clean and reapply thermal pastes and clean out fans and reseat memory.  I'll try only using one stick. Maybe one went bad. They are pretty old.

yep, it was a dead ram stick.. Very weird. in my entire life of building computers this is the first ram stick ive seen die without something physically happening to it.. It was perfectly fine one second, dead the next second..

And idk why ddr3 is still so expensive. ddr5 is about to come out.. cot damn!

Well i't may look dead, but sometime when you clean it, it will work.

Use pencil eraser on the copper fins, old memories usually have oxidation on the copper.

I had plenty of success using this method when i'm rebuilding old core 2 duo units.

hmmm.. I'm gonna try the pencil eraser. I usually just use a scalpel to lightly scrape up the pads. Ive always had good success with that on old battery terminals or corroded pads on old electronics.. I like that eraser idea though. Less damage to the pads.
