My PC starts up only after being left off for a while
I just put together a new computer with these parts:
Ryzen 7800X3D
ASUS TUF Gaming X670E-Plus
Lian Li Galahad Trinity II
RTX 4070 SUPER
Kingston Fury 6000MHz
990 PRO 2TB
MSI MAG 850W
NZXT H9 FLOW
Right now, my PC is placed on a stand outside the case. When I first tried to power it on, I heard the GPU and PSU fans spinning, then a click from the PSU before everything stopped. I checked all connections and disconnected everything except memory, CPU, and SSD, but nothing worked. The next day, after returning home, the computer started normally. But when I tried to turn it off again, it wouldn’t power on, and the same happened with another PSU I borrowed from a friend. Could you suggest what might be wrong? I’ve never seen anything like this before.
Welcome to the forums, newcomer!
Bench? It might be worth checking if the system functions identically when breadboarded (not on your testbench). It appears there could be a grounding problem. You may also consider moving it to a different wall outlet.
Thank you for the update!
At first, I put it together inside the case, but when the issue arose I took it out of the case.
I tried it in a different wall outlet and the same problem continued.
Could you suggest another approach?
Appreciate your help!
Disconnect the PC from the power source.
Press the power button to discharge the PSU capacitors.
Reconnect the PC to the power supply again.
Observe if it begins functioning.
Possibly suspect the PSU.
Thanks for the update. It functioned once but not the second time. How long should I continue this process? I'm using a screwdriver to activate it on a test bench. Do you think the issue lies with the power supply? I tried it with a friend's and the same result occurred.
It's a really puzzling problem.
I observed that taking the power cables off the CPU still allows the PC to boot up properly.
This suggests the issue might not be with the CPU itself but could involve the motherboard or other components.
There might be another explanation for the problem.
