Question

Help troubleshooting booting issue

May 5, 2019 2:22AM PDT

Hi,


I'm fairly new to building pc, i built one last year as an exercice with cheap parts, and this year i wanted to build a good computer for me, but i think i may have messed up something.


So the trouble in itself is that the computer turns on for 5-10 seconds, then shuts down, and start again, and shuts down again and so on. I don't have any beep code (i plugged a headset into the mobo jack, don't know if there is another way), i don't get a graphic signal, so i guess i'm not reaching the bios.

I swapped the graphic card and the psu with the ones from the computer i built last year to check, so i know the ones i have now work fine. So it is either the ram (which i plugged just one in every slots possible), the cpu, or the mobo itself.


I think it might be the rams that are not compatible with my mobo. I bought a ryzen 1700 with a asrock x370 killer sli mobo and 2 ddr4 3000 hz ballistrix rams, and the mobo manual actually states that maximum frequency is 2666 on dual channel i think :



But i also read online that motherboards usually are still able to fonction with higher frequency memory rams. Are the symptoms i get really from the too high frequency ?


I thought it may be a bios update issue, i'm really not knowleadgeable on that, but since ryzen 1700 is first gen i thought i wouldn't have any issue with it.

Make it smaller

Unplug all disk and disc....test.
Unplug all ram......test.
Remove the gpu....test.

If all that fails move the mobo to a piece of cardboard....test.

You need to get it to power up and stay up.

it's smaller now

the motherboard is out, it was already just connected to the psu, the cpu, the gpu and the rams.

I just tried to run it without the rams and without the gpu as well, the pc still shutdowns after some time, i also reapplied thermal paste, but i don't think it's a overheating issue. Should i try maybe to pull out the cpu and put it back in?

Smaller

When you get down to psu/mobo/cpu+hsf and it won't power up and stay up on cardboard your down to 3 parts.

Contact the seller of these parts and ask what they want to do.

pins vs hairs
May 5, 2019 8:19AM PDT

CPU used to have "pins" but they should call them "hairs" now, they are so thin and hard to see, and so many of them. Pull the CPU and with magnifying glass check that AMD to be sure no bent "hairs" on it. They are so easy to bend when installing to socket. I've used thin toothpicks and coffee straws to line them up when bent.

Ok

Thanks for the tip, i will try that. I actually removed the cpu from the socket, and i found that a bit of alcohol solution went in the "hair" of the cpu and in the pin of the socket, i think i might have goofed on that one :s ...

I'll try to clean it when i get proper ethylick alcohol, and i will try to see if i bent anything as well. Hope i didn't fry both my mobo and cpu tho...
