Help\Suggestions on a possibly dead PC
rarely encounter completely failed CPUs, except when overclocking. More likely it's a motherboard issue. If all else fails, take apart everything and remove the board from the case. Connect only the necessary components to try posting again. If posting still doesn't happen, it could be RAM problems, but having two sticks fail simultaneously is unusual unless the power supply is damaged. Assuming the PSU works, I'd bet on a faulty motherboard if RAM has been excluded.
Still no hope. Replaced the Xeon CPU with a reliable one, but nothing changed. The CMOS battery also failed the same problem. Without an LGA1150 motherboard, I can't verify if the CPU is working properly. Now I'm stuck using an iMac to stay productive.
Capacitors and power supplies are becoming less frequent issues these days, and I haven’t encountered one to repair in a year. Back then, faulty capacitors in power supplies were more common. Regarding motherboard capacitors, the machine I used last year had two that required replacement.
Unfortunately the issue escalated further. Initially it would start the CPU, GPU, and case fans but wouldn’t boot with either of two different CPUs. Then it completely stopped functioning now—no signal at all. It seems like it’s not even connected. This is definitely a problem worth addressing. The question is whether spending $200 on an LGA1150 MOBO just for testing a CPU is worth it, or if it’s better to build from the ground up. I was really satisfied with my current setup—it performed perfectly without any need for the newest components. Now I’m considering a completely new build. Someone should create a platform where people can swap or trade parts, especially for those who just need to test old components.
You're experiencing an issue possibly due to a faulty fuse on the board. The key is locating it. If you recognize the fuse type, you might use a multimeter to test it and fix it so the system restarts properly. Such fuses often fail over time, especially after prolonged operation, leading to power loss gradually rather than a sudden failure. Your description suggests the problem developed slowly, which points more toward wear than a hardware defect. Simply replacing the fuse with an identical one from another board should resolve the issue. This process needs some soldering skills and tools, but if you're prepared, it's manageable. Make sure to verify the fuse type before replacement.
Are you certain power reaches the CPU and GPU?... It seems more likely the PSU is the issue, since they often lose effectiveness over time.
