Constant USB Disconnection/Reconnection Noises with no devices connected. Just discovered a laggy BIOS

[sourceofvegemite]

Hi all,

 

Recently booted up my computer yesterday only to be greeted with the sound of a USB device connecting repeatedly every second.  Went through all the shenanigans of uninstalling USB Drivers and reinstalling, only for the error message to continue appearing after reboot

 

I used USBDeview and found that there was a connection labelled Port 5 Hub 1 that was consistently connecting and disconnecting, even with all of my USB devices completely disconnected.  I went back and found that by uninstalling one of two AMD 3.1 eXtensible Host Controller's, I was able to get rid of the error message.  But it killed all of my USB 2.0 ports on the case and motherboard.  I ran a fresh install of the AMD Chipset Drivers from their website just incase.

 

Now today, there appears to be no error message occuring, but the bootup time is now multples of seconds longer than it used to be.  Recently went into the BIOS, only to find that it took an extremely long time (comparative to when I first built this machine only a couple of months ago) to post, and that it was laggy and unresponsive for a large portion of time.  Only after sitting in it for a few minutes did the system become "stable" and smooth like it had a month or two prior.

 

Specs:

CPU: Ryzen 5 3600

MB: ASRock B550M Pro 4

RAM: Corsair Vengenance LPX DDR4-3200mhz

GPU: ASUS ROG 2070 Super Advanced OC

PSU: Silverstone Strider Gold S Modular 650W

Storage: WD Black 250gb NVME + 2TB WD Blue HDD

 

My first thoughts are that perhaps the motherboard is slightly defective?  Unfortunately I've thrown away the box that it came in, but I would probably still return it as now defective as it was only purchased a couple of months ago.

 

Next thought would be the powersupply, but this is also new and seems to be powering everything well.

 

Final thought is that perhaps when I did a fresh install of the AMD Chipset Drivers, the motherboard got extremely confused.

 

Not sure what to do here, any help would be great thanks!

Sounds like you may have a faulty USB controller on the motherboard.

Definitely feels like it.  Problem disappeared the next day but it has resurged with intensity.

 

Would the solution be to RMA it?
