Hi,
Specs details:
PSU Cooler Master Silent Pro Gold 550W. Motherboard Gigabyte 970A-D3, CPU AMD FX-8320, Cooler Master Evo Hyper 212, Graphics card Asus GT 1030 passive cooling, case Fractal Design Define. The whole computer was assembled in 2014.
I take great care of my computer (no dust, thermal paste new). But unfortunately I made a blunder by placing the desktop case on a carpet floor. I forgot the case has an air intake from the bottom . The obstruction has caused the PSU to work harder. With the summer heat it was too much and the PSU had gone under.
Symptoms began by the screen freezing. Hard reset, power off/on cycle, etc. could not restart the OS. The screen remain blank, not event the BIOS screen could be displayed. Opening the case, the most obvious sign I have seen is actually the CPU cooler which is uncomfortably warm. All fans works OK. No smell of burning. All other parts of the computer are cool. The CPU just get hot within a minute as soon as the power is on. I just feel that by touching the aluminum fins of the cooler. Unfortunately I forgot to touch the PSU casing otherwise I would know it is the culprit. The screen displays nothing. No beep pattern b/c the case has no speaker.
In daily operations, this CPU never got warm during its lifetime, I have never seen the CPU cooler getting even slightly warm. The usage is office work and casual surfing. No gaming. The hottest part used to be the heatsink on the chipset. The whole computer works great since 8 years.
I have unplugged the peripherals one by one and rebooted each time. The last part I tried to swap was the PSU. And then the motherboard can reboot and the computer works like before.
QUESTION: what is the technical reason for a PSU to malfunction in such a way that it only overheats the CPU while not being able to boot at all? I would like to give some hints to the person to whom I am giving away the PSU. Or maybe should I throw that PSU in electronics recycle?
