I added a heatsink, which helped it operate for about 4 minutes. After that, I powered it off again...
I thought the CPU could overheat during the last setup, so I connected everything outside the case. The CPU felt quite warm, which might have caused the computer to stop earlier. With AIO connected, it adjusts fan speeds automatically when starting, giving the system some stability. Still no clear resolution.
I also tested a different GPU to confirm, but it didn’t boot. I attempted to post for about 30–40 minutes without assistance. Everything lights up except when I insert my keyboard. (The keyboard has RGB lighting.) My PC illuminates, and the fans spin, but no posting occurs.
Hey, disconnect everything as much as possible—storage, other PCIe cards, USB devices, RGB controller, even the front panel USB. Expect a motherboard, CPU, cooler, and at least one memory stick (check the manual for slot numbers and try different sticks). Keep the keyboard separate from any fast USB ports; they might react strangely. Plug the monitor into the motherboard. Ensure the CPU 12V supply is connected. Reset CMOS by using the jumper or button while the PC is off, then power it on and let it warm up for about 10 minutes (not longer than 40).
Hey there. I see you're facing some issues connecting your motherboard. It sounds like you're dealing with a Ryzen 7 9800X3D chip, but you haven't received any assistance. Have you checked the compatibility of your components or looked into the manufacturer's support resources? Let me know if you need further guidance.
According to @leclod, it's possible but there seems to be an issue. You can only replace parts until it functions properly—it feels like you've already tried many changes, but it's hard to understand what's wrong. Are there any components you haven't swapped yet?
I haven't changed anything except the case. I'm working on bare ground. I've tested two new CPUs and two different GPUs, because they were part of earlier PC installations. One motherboard is new, the other is from my previous setup. I'm using two different MOBOs; one seems to be dead since it didn't light up, but it turned on when I pressed the Q flash button. All my recent tests were done on another brand-new MOBO I bought 22/2, but it still hasn't provided any updates. Regarding the HDMI connection on the motherboard, I checked it too, hoping for a solution, but it still shows 'no signal'. I'm considering returning everything.
In my view, there are just three scenarios. 1. A component is faulty and causing damage to others, like a broken PSU affecting several parts, such as two motherboards. Unlikely but possible. 2. Two items are damaged—perhaps the original board and a replacement one. Very improbable. 3. The issue lies with you. Likely and probable. You probably made a mistake, like connecting a cable incorrectly. Normally I’d recommend dismantling everything and taking it apart, but it seems you’ve already done that. It would be best to bring someone else in for a thorough check.
