The motherboard is powered, yet the computer fails to start.
Attempted to unplug the GPU without success in turning it on. The white light is functioning properly, but it only lights up when the power supply is connected. Disconnecting the two 8-pin connectors shows red lights, indicating the motherboard is receiving power but possibly insufficient. I’m leaving town and returning tomorrow, but it keeps occupying my thoughts. Could be a dead CMOS battery?
It starts when there are delivery issues. If you can't boot without the GPU, it might be another problem. Try connecting the monitor to your mainboard and see if it works—just make sure to unplug the GPU power cables. The CMOS battery could be the issue; if you have a volt meter, it should read around 3V for replacement. A new one should have 3.3V using a CR2032 battery. I’ve rebuilt my setup in similar steps, including replacing the 9900K and two 2080Ti GPUs in a fully watercooled case with new radiators last year. With your case, swapping the front panel for a distroplate might be better.
Gpu is not connected right now, but we had to leave for an out-of-town trip yesterday, so I couldn't finish. Tomorrow I'll test the CMOS battery. My wife will be upset if I say I need to buy a new motherboard and CPU, so I'm guessing it's either CMOS or power supply.
Don't worry about having lots of carpets—static issues can be blamed on the carpet if the mobile is dead. A 6-7 year lifespan is typical for a system, and I'm planning to swap out my equipment soon.
We’ve got plenty of space upstairs, but I double-checked the table before lowering it. I’m grabbing a fresh CMOS battery and PSU on the way home today to see if that solves it. That’ll save me one purchase later when I upgrade. No carpet downstairs—my desk is the only floor. I’ve been doing my best to keep it in top shape. My aim was 10 years of use. Fixing this could extend that a bit. Once it can’t hit 60fps at 1440p, it should still work in 1080p. I don’t enable ray tracing yet; I’m getting 60–100fps in games like Call of Duty, Assassin’s Creed, Rust, RuneScape, and VR. I skip 4K since I know it won’t perform well. As long as I maintain over 60fps, I don’t feel the need to spend a fortune now. That’s why I invested as much as possible from the start, adding case upgrades, water cooling, fans, newer NVMe drives, etc. When I’m ready in a few years, I’ll replace the motherboard, CPU, RAM, and install a bigger PSU (unless the new one fixes it). I’m planning a 1200-watt setup. Probably I’ll wait on the GPU as long as possible. My idea is to retire the rest and use the old case for my woodshop PC. Even as a kid, I never thought the cost was worth it all at once—so I built it slowly between 2016 and 2017. It’s disappointing that the new motherboard costs over $600 now, while the one I had was just $250 back then.
Uncertain about the problem. Various locations and videos suggested it might prevent the system from turning on. I haven’t faced any issues with this PC before, so figuring it out is challenging for me. Today I’m heading home to replace the CMOS battery and PSU, hoping either will resolve the issue.
Here are some images of what you're working with. The setup includes lights, but it doesn't power on even after switching the power supply to the motherboard and CPU. Do you need additional components beyond the 24-pin motherboard and 8-pin CPU to test?
