Since this morning, my PC has stopped powering any of my peripherals for over three seconds. When I plug in my keyboard, it briefly lights up before going dark. No other devices illuminate. The monitor keeps showing "No signal." The headset remains silent with no beeping.

What I've attempted:
Restarting the computer
Switching ports and checking the power cable connection
Testing peripherals on another device
Reinstalling RAM modules
Removing one RAM stick at a time
Inspecting the PSU
Verifying the CPU fan header
Taking out the CMOS battery and reinserting it
Testing the graphics card heatsink for operation (it was warm)
Checking if case fans and PSU fans are spinning, though the graphics card's fan isn't. It seems the issue might be linked to the "0 RPM" setting on the card, not a general problem.

I also recall past PSU issues that caused peripheral damage, but after returning the power supply for repair, there were no further problems. The pin voltages are still within normal limits.

Welcome to the forums, newcomer!
PSU: EVGA 600 BR
What is the age of your PSU?
I also want to mention that I've experienced PSU issues before, which sometimes damaged peripherals, but after returning the item for replacement, there were no further problems. It seems like this isn't a PSU problem since all pin voltages are within the expected range.
You should obtain a well-built PSU from a reliable source with at least 650W to power your entire PC and check if the issue continues.
