A short, prioritized troubleshooting checklist to isolate whether the problem is the motherboard, CPU, or something external — building on ’s pointer about CMOS/voltage checks and the original report of no display/no beep.

  • Verify the video path first: confirm the monitor and cable work with another PC and that the monitor input is correct. If the board has both onboard and discrete video, try the other output (or a known-good GPU) so a bad video card or cable is not mistaken for a dead motherboard.

  • Look for power/POST signs before swapping parts: motherboard standby LED, any CPU/GPU fan spin, and the presence of POST/Q‑LED indicators (many boards report CPU/DIMM/VGA/BOOT state). If no speaker is present, connect a simple internal PC speaker to the board’s speaker header to catch POST beeps.

  • Clear CMOS properly (jumper or battery): disconnect mains, discharge by pressing the front‑panel power button twice, move the CMOS jumper or remove the cell for 1–5 minutes, then restore and try a boot. This is often quicker and safer than random part swaps.

  • Breadboard the system outside the case on an insulated surface: only motherboard, CPU + cooler, one known‑good RAM stick in the recommended slot, PSU main 24‑pin and CPU 4/8‑pin connected, and speaker. This rules out case shorts or misplaced standoffs.

  • Visual inspection and socket care: check for bulging/leaking capacitors, scorch marks, bent pins in the CPU/socket area, or misplaced standoffs/screws. Reseat the CPU and cooler carefully (watch for bent pins on PGA CPUs or debris in LGA sockets).

  • Measure or test power rails if possible: use a PSU tester or voltmeter (as suggested) to confirm 3.3V/5V/12V and 5VSB are present before blaming the motherboard.

  • If the board supports USB BIOS Flashback or recovery, try that per the vendor procedure. If the board is still totally unresponsive after the above (no standby LED, no POST activity even with speaker attached), the failure is most likely on the motherboard or CPU and should be isolated with known‑good replacement parts or professional diagnostics.

Safety note: always unplug mains before moving hardware, use basic ESD precautions, and avoid shorting pins or traces.

Tell more. For example some models do not beep but hold in reset when the CMOS battery is too low.

Tell more. As a PC Tech I expect you to have a Volt meter at the very least to measure and check things. If not, just pop in new batteries as they are cheap in bulk.

And again, tell more. I see nothing about the PC and why you replaced the PSU. Did you measure it? What told you to replace that part?

I'm sorry, i didn't know what to do anymore so, i just tried everthing. I don't know what's the problem now

Since you didn't list what you tried, it's tough to add a new idea except to take it into the shop you deal with for such work.
