System Power Loss - Motherboard Issue?

[Deleted member 629125]

Hi,

I've had my system for the past year, coming up on two. I've just recently began having issues with my system seemingly partially turning off, with all USB devices and presumably internals turning off. My video signal will be non-existent, yet the fans on the case, CPU, and GPU all continue to run. What could possibly be happening? I've managed to temporarily fix this issue by turning the machine off for approximately 15 minutes and attempting to boot it again, but the problem persists, happening at random.

My setup:
Motherboard: MSI 870A-G54
CPU: AMD FX-4100 Zambezi Quad-Core
GPU: Zotac GeForce GTX760 2GB VRAM
PSU: Cooler Master Extreme Power Plus - 500W Power Supply

this problem is simillar to the one i had with a dell optiplex 160l a few years back .. in the end it turned out to be a faulty motherboard that just lived its life so i had to replace it and everything went back to normal .. sometimes my pc would just stop responding to the usb and keyboard ports rendering the pc useless for a bout 30 minutes and then back to normal and before i know it ,the problems is back .. i would suggest that you get a new motherboard and save your self the trouble
