Question MSI Z97 PC Mate USB Issue

[spoutnik1992]

Hey guys,

I have a Z97 PC Mate motherboard, running windows 10 (Motherboard is less than a year old since I first used it)
Everything was working like a charm.
Since 3 days, USB 2.0 and USB 3.0 (motherboard integrated USB) are not keeping ANYTHING plugged in. No matter what USB I will try.
USB will flicker, connecting and disconnecting, on and on anything I will try to use.
I can hear the USB sound.

I did a fresh new windows installation just today and nothing improved this problem, still doing the same symptoms.
Checked MSI website for USB drivers, but nothing listed seems to impact USB drivers.

Any ideas?

EDIT :: Issue occur with certain things (ex: Iphone won't properly connect, mouse or USB key will properly connect, HTC Vive won't properly connect, etc...)
EDIT 2 :: I did uncheck "Allow the computer to turn off this device to save power" under power management, under Device Manager. I also did Disable under power options "USB selective Suspend settings".
EDIT 3 :: Installed latest BIOS update available on MSI website for motherboard.
EDIT 4 :: I just removed CMOS battery and put it back in after 10 mins... No improvements... I believe either Motherboard or PSU is failing... But I can't tell which since... USB still works with some devices such as keyboard/mouse...

At this point, any idea ??? I am discouraged...

Small update, I changed motherboard and the issue got fixed. Seems like it was a sick motherboard, I found out after hours of research to see difference between PSU and motherboard "sick" symptoms.

Thanks anyways.
