Or by only putting one stick of memory in, or changing the slot you’re using.
I was assembling a computer and everything seemed to be correct, the fan would spin up, I’d get some lights, but there was no image on the screen, not even the BIOS. I saw someone else make this suggestion and didn’t think it was likely to work, but it did. First I just tried one stick, and it booted. Then I tried both sticks and it didn’t work, but I reseated and then it did.
(Also worth pointing out that your motherboard should have diagnostic lights which if you check the documentation may point out which component has an issue)
Thinking about Lemmy’s demographics many here may have heard of something like this, or have more helpful suggestions about troubleshooting which would be welcome. But thought I’d write out a little post about my experience to contribute to Lemmy SEO supremacy.
My aging work PC (Xeon E3 1230V2) regularly stops booting, and this works for me. It had 16gb of memory, but I had to throw out one of the sticks. The other thing that gets it working again sometimes is tightening or loosening the CPU cooler screws. Thankfully, it’s old enough to still do the BIOs beep codes which tipped me off to the tightening the CPU fix. I’ve got some newer parts lying around (an AMD 2600x and 16gb of DD4) I’ll turn into a full PC when it finally dies, but for now it just keeps going and going.
