Pc specifications include an RTX 3080, Ryzen 7 5800X3D, Corsair h115i Elite Capelix, aio liquid cooler, 32GB RAM, Corsair Vengeance DDR4 3200/1000W, EVGA Supernova G+, and Aorus B550M Pro. After moving in, the PC booted normally but wouldn’t power on after turning off. I disassembled it, tested the PSU with a jump bridge, and found it dead. Replaced the PSU with an EVGA unit and it worked immediately. RAM lit up when I connected it to another system, suggesting it was getting power. The GPU didn’t light up or spin, but fans and the pump didn’t work. The new PSU is running fine. I moved the GPU to my brother’s PC, which functioned perfectly—planning to test the CPU next. If the CPU runs when I try it, it likely points to a motherboard issue. The RAM was receiving power, so GPU and CPU slots probably aren’t damaged. Thanks for the help!
Additionally, I'm curious about the possible reasons behind this. If anyone has suggestions on how to prevent it from occurring again in the future, that would be greatly appreciated.
It might be that the motherboard, power supply unit, or a connected part is damaged; attempt to start with no connections to any ports. If everything powers up, connect a monitor and if it works, place your mouse or keyboard on it. If it fails, try opening the case and inserting a spare PSU into the 24-pin and GPU 8-pin/12V HPR pin/6-pin CPU slots to rule out power issues. If that doesn't work, consider using a USB-C display adapter for the broken screen or use remote access tools like TeamViewer to check your system without a screen, reviewing device manager or event viewer. This could indicate a faulty display driver or a dead GPU.
When I checked, I just connected it to a breadboard, and the fans didn't spin, the cooler RGB stayed off, and only the RAM sticks' RGB lit up. I tested the GPU and CPU in my brother's PC, which both functioned normally. The motherboard showed no error lights or sounds, and the new PSU was brand new—likely not the problem. It worked with the jump bridge too, though it might be defective.
I think the motherboard is likely the issue, though I'm not a specialist.
I agree with your assessment. It seems the motherboard is the only remaining possibility if everything functions elsewhere. Removing it from the case would also eliminate chances of a bad standoff or shorting the board. The PSU might be less likely, but my gut doesn’t suggest it’s probable.
