My system fails to boot quite frequently, and I can't figure out why. It happens maybe 80% of the time. The symptom is no display output whatsoever. I've tried both the GPU display output and the motherboard's built-in display output. The fans on both the GPU and CPU cooler spin up, and a USB keyboard clearly gets power, but there are no other signs of life. The really weird thing is how inconsistent it is - sometimes the keyboard works fine in that pressing the numlock key toggles the numlock light, and same with caps lock. But other times, the numlock lights up during boot but isn't responsive to key presses at all. When stuck in this unbooted state, sometimes it shuts down cleanly with a short press of the power button, and other times it requires a long press to do a hard shut down. Also, the mobo manual says that there should be debug LEDs on the mobo itself, but I haven't seen them light up ever. The BIOS flashback light also never turns on, even when doing the flashing procedure. So far, I've updated the mobo BIOS to the latest version (confirmed during one of the rare times that I was able to get into BIOS), cleared the CMOS, and tried using different display outputs. I'd rather not have to reseat the RAM as it's under the cooler and the PSU cables around there are very tight.

Hello... I have a few questions. 1. I'm not very comfortable with Linux since I'm used to Windows, but I'm willing to help. Could the Boot Partition be damaged? I recall in Windows sometimes this happens and fixing the startup files might resolve it. 2. If the rest of the system is receiving power correctly, I wouldn't focus on RAM or PSU, so I'd be concerned about the CPU. It's rare for a CPU to fail without physical damage, but it does occur. I’d try re-seating the CPU and check the thermal paste to see if it’s sufficient. 3. Regarding the thermal paste, if you can access the BIOS, review the CPU temperatures. High temps could indicate a need to replace the paste or cooler. 4. Try to obtain a USB DVD drive. I remember KNOPPIX booting from a disk without needing a separate storage device. If that works, I’d examine the entire Linux partition or the self-contained storage drive.
I believe so. After startup, it launches into Linux without issues, and the POST display shows up before the BIOS takes over. I’m willing to try re-seating the CPU—there seems to be sufficient thermal paste, with a little extra on the cooler plate, so everything should be adequately covered. During boot, CPU temperatures are within normal ranges: psensor shows idle temps around 35°C, and gaming pushes it up to about 82°C. Regarding storage, I’m not sure about a DVD drive; a bootable USB should work fine. In my opinion, the problem isn’t the operating system since the POST screen functions regardless of installed OS, and it should still boot without any drives.
You're right about using a USB drive for KNOPPIX Live OS—it's a familiar method from the days of floppy, CD, and DVD installations. Just checking if the pattern matches with standard Linux setups. There are a few concerns though: too much thermal paste might damage the board, and a high 82°C reading could indicate underlying issues like poor contact or cooling problems. A bad paste or CPU contact can cause overheating, so it's wise to test with a cooler if needed.
