Here is what I've tested:

• The issue occurs in both Windows 10 and Linux Mint Cinnamon.
• I tried two different 3.5 mm microphones, and both have the same problem.
• The front and rear microphone jacks both produce the same buzzing.
• I reseated the front panel HD Audio connector on the motherboard.
• The motherboard uses a Realtek ALC3220 audio codec.
• The microphone buzz is present in all recording applications.

What could have failed on the motherboard that would cause this? Could the PSU replacement have damaged the onboard audio circuit, or is there another likely cause? Are there any tests I can perform with a multimeter to determine whether the problem is the motherboard, front panel audio board, grounding, or something else?

Any troubleshooting suggestions would be appreciated.

Please help me i really need mic

​I've already tried resetting CMOS, reseating the RAM, cleaning/reseating my GT 1030 GPU, and testing the built-in motherboard port, but nothing works. CPU cooler is tightly installed and thermal paste is fresh.

​Could this be a PSU failure or a motherboard issue? Thanks in advance!

I’m seriously stuck with this and need help diagnosing it.

My PC started randomly restarting about 3 days before the SSD/RAM replacement. It would suddenly lose power and reboot during normal use.

The technician told me the old HDD was failing and that the motherboard needed servicing. He thoroughly cleaned and serviced the motherboard, and reapplied thermal paste to both the CPU and the smaller motherboard heatsink.

I then replaced the HDD with a new 256GB SATA SSD, replaced the RAM, and installed a completely fresh Windows 10.

The exact same problem is still happening.

I also tried:

• SSD + HDD connected
• Only SSD connected
• Only HDD connected

The problem persists in every configuration.

Windows boots normally, I log in, and after a short while the PC suddenly loses power, the LEDs go off, and it restarts.

At this point I’m honestly completely helpless and desperate. This PC is extremely important to me, and I’ve already spent money replacing parts and servicing the motherboard, yet I still don’t know what is actually failing.

The problem started before the SSD/RAM replacement and survived:

• Motherboard servicing
• New SSD
• New RAM
• Fresh Windows installation
• Different HDD/SSD configurations

• 256GB SATA SSD
• 1TB HDD
• 8GB DDR3 RAM
• Gigabyte H61M-S1 Rev. 2.0 motherboard
• No dedicated GPU
• Intex 450 Techno PSU

Please help me figure this out. I genuinely don’t know what else I can do at this point.

Today suddenly my PC stopped booting up. It worked like a charm and suddenly stopped.

Once powered on it starts, CPU and GPU are spinning, but no signal comes on monitor. I tried checking RAM, plugging HDMI into MOBO, removing and reinserting graphics card, nothing helped.

I found out that restarting CMOS let's me into the BIOS, but once I'm out it's back to square one.

But this shows that monitor works and GPU outputs the BIOS at least. What else can I check?

Below are my specs visible in BIOS:
