What else is there?!

[Froggo56]

I had an old HP desktop with a i5 8400 in it. Bought a ASRock Motherboard H310M-ITX (actually i bought 2), i got Corsair Vengeance LPX 16GB (2x8GB), and a node 202 with a psu.

 

But there is no boot. It turns on and then shuts off within a second or two. I've tried 2 motherboard, i bought the RAM bc i thought that it may have been shot, and the PSU has been tested and it does work. Wiring was checked then double checked (by unplugging and re-plugging to see if there was a loose connection)

My mind is boggled and i don't know what else it could be.

 

(on a side note the RAM and the CPU did work on the HP, i did re-use the MB its old PSU to double triple check parts, regardless of whats in the Node202 it wont boot)

I'm gonna blame the power supply.

 

How did you test it?

Used the jumper to make sure it turns on, then i plugged it into the old HP and it worked

try to build without the case, put insulation under the board (even cardboard will do) and test whether it turns on for some time. It could be the case shorting the board out triggering a shutdown

Did that too, thats why i bought another MB. Thinking that it was dead

I returned the old MB

Did you put the CPU back into the HP and retest it? If not, maybe it got damaged it at some point during the swap.

What PSU did you buy? As mentioned by someone else, it very well looks like a PSU issue. Assuming you didn't purchase a shit one, you can try one of these to test it: https://www.amazon.com/HDE-Power-Supply-Tester-PCI/dp/B005UZHB6G

The PSU came with the Node202. And it does sound like a PSU issue, but i wound up plugging ones i know that work into the MB and still nothing... could it be a bad ground somewhere on the motherboard?

Yes, the old ram, the cpu, and the new PSU from the node202 have all booted off of the old HP

[Froggo56]

Honestly, even though ive been through multiple MBs, i think its that. It looks like a bad ground or something.

Perhaps there's a short between the board and the case. Take everything out and put it on the box your motherboard came it and work from that.

Can do, ill keep you posted in a bit. Just got to work . If it is, is there a way to fix\prevent that?

That would depend on what's going on. Could be a longer piece of solder sticking out from the m/b that's making contact with the motherboard tray. Could be missing a standoff inbetween the m/b and tray. Could be a piece of the I/O shield sticking inside one of the ports (that's happened to me once or twice). We'll just have to experiment and see.

Not my first time down this rabbit hole, thank you for the advice and for the time. It means a lot

I cant upload any more photos, BUT the only way this pc boots is without that MB

 

Case solved, again thank you for all of your help! It's good to know its not the PSU, RAM, CPU (deadass the more expensive parts to this build )

I'd like to retract my last statement...

 

New Gigabyte b360 MB and still the same issues. And yet, everything works fine on that other motherboard. The CPU is a i5 8400, am i buying like the wrong chipset???

B360 is 8th and 9th gen, so it's the correct chipset. I'm wondering if any of the hardware, like CPU or RAM, is hardware locked just like Apple does.
