PC Locks up + Reboots and Random USB Device Disconnects REVISITED

SOLVED: It was my G203. I think it's disconnects were causing every other USB device to drop off too. Thanks for the help.

Hello everyone,

At the beginning of this year, I posted a thread which detailed my experiences with my newly built PC experiencing random reboots and extremely loud buzzing sounds from my PSU. Half a year later, and this problem is still not solved.

As a reminder of the situation in summary: My pc locked up randomly and rebooted, with extremely loud buzzing sounds coming from the PSU every now and then. Every component in my system has been stress tested, and nothing out of the ordinary happens during these stress tests.

Here are the system specs:
GTX 780ti
Ryzen 5 2600
32GB DDR4 3200MHZ RipJaws RAM (2x16) clocked at 2933.
1TB Seagate Barracuda HDD
256GB Crucial SSD
Gigabyte P650B PSU
Gigabyte B450M Aorus Elite motherboard
3x Deepcool RF120FS case fans at the front (all 120mm)


Since then, the situation has changed. The random reboots are extremely rare from what I have observed overtime, maybe only happening once a month. However, as time moved forward I also experienced my USB devices randomly disconnecting. My mouse, keyboard and PS4 controller as well as a tablet which I used to play OSU with.

Just the day before yesteryday, I figured I'd finally switch the PSU out with with another one from my other builds. It is a 550 watt Corsair V550, sadly the only other PSU I had to test with (I know, it's cheap).
Since then, what I can say is that the mouse disconnects definitely seemed to have died down in frequency, but are however still present. Once again they occur randomly, sometimes in games and other times just on the desktop.

At this point I'm truly stumped. Could it be the motherboard? Or could it still be the power supply not supplying enough power to the system? I know under load my system only uses a max of ~460-470 watts.

Finally, here are all the things I've tried a side from swapping out the P650B with the VS550:
Using different USB ports. (the front panel connectors also seem to be affected).
Updating my BIOS to the latest version.
Stress testing every single component which I can (GPU with Kombustor, CPU with Prime95, RAM with Memtest86 which passed all phases).
Disabling USB suspension in Windows power options as well as disabling "Allow the computer to turn off this device to save power" in device manager for all USB controllers and USB devices.
Updating graphics drivers.

Today I'm planning to reinstall Windows completely.

Any help would be appreciated,
Thank you.

Note: Also forgot to mention that when I updated the BIOS, it reset my RAM to 2133MHZ without me knowing. During that time, the mouse disconnected so I believe I can rule out a funky memory controller.
 
Do you have anything in event viewer?

I assume you've tried with a basic mouse and keyboard and no other devices?

Checked for shorts (loose screws and cables and stuff)?

Checked for contacts around the I/O shield, something pressing where it should not, grounding issues?

Can you test the PC outside the case?

Thank you guys for the replies. Funny enough, yesterday I decided to use my office mouse (some HP) instead of my Logitech G203. Since then, it has not disconnected once during my time playing GTA V and some casual Siege. So from here I think I can deduce some causes(?)
1: Either the mouse is faulty and is causing everything else to drop off with it OR
2: The motherboard is not able to provide enough voltage for it?

I did some browsing on other forums and I did see some threads of people talking about how their single peripheral (a mouse or a keyboard) was causing all their other devices to drop off. Also had someone tell me this could be the case on one of the forums I asked on.

I'd find it unlikely the motherboard can't power a mouse, but if it's been in a usb 2 port you could try a usb 3 one.

I've tried a variety of USB ports, front panel and also back panels (both 3.0 and 2.0). Would USB 3.1 make a difference? They are the red ones on the back of the B450m Aorus Elite.

I doubt it, the power draw of a mouse won't exceed usb 3.0. I guess if it was faulty is might be tripping something that is protecting the usb ports.

Hmm alright.

Also, another weird development:
I used the HP office mouse for a majority of my morning playing GTA V, no disconnects. Then I decided to switch back to the G203. It's been roughly 5 hours since then, and the G203 hasn't had a single disconnect. I'm genuinely confused.
