After upgrading the CPU, no power remains available.
Hey there, I see you're dealing with a tricky setup. Your system seems to be experiencing power and boot issues across multiple components. It’s possible the motherboard is struggling to deliver power, especially with older parts like the PSU or RAM. You’ve tried several fixes—switching cases, changing RAM, using different CPUs—and still faced problems with lights, fans, and no startup. The fact that you’re seeing partial improvements with games suggests the issue might be isolated to certain components. Have you checked the power cables, PSU connections, or maybe the BIOS settings? Also, consider testing with a known-good PSU and RAM to rule out hardware faults. Let me know what you find!
Have you attempted to discharge the CMOS battery for five minutes before retrying?
Likely the motherboard. The same issue occurred with me last month after upgrading the CPU—now it won’t power on at all, though the RGB lights were still active. I followed all the advice from YouTube, including CMOS and RAM cleaning, but nothing helped. Eventually, I replaced the CPU and swapped out the old motherboard; it worked for me. Consider trying a different motherboard next time.
I placed an order already, just to be safe. I’ll test it once it arrives.
Long shot, but perhaps another issue is at play—like a short in the GPU power cables or a SATA device. I tried connecting just the motherboard, nothing else works. Have you got an older CPU, such as the 3600, to see if the system boots up without any connections (no GPU, etc.)?
