USB devices freezing

divineausir · April 25, 2020

Built my parents a computer last year, been having problems with it freezing.

Mouse and keyboard disappear and stop working, but video keeps going.
Fresh installed OS when I built it, updated drivers/bios/chipset, swapped ram out for my single stick of Crucial, messed with power settings, set ram to run at full speed in BIOS, and some other things. This has been ongoing for almost a year now, sometimes it stops for weeks or does it multiple times per day.
There's a distributed COM error in the event viewer that I tried fixing following another forum post before but didn't help.

Let me know if you need anything more. Any help is appreciated!

Specs
CPU: Ryzen 5 2400G
MB: ASUS Prime B450-PLUS
RAM: G.Skill Ripjaws 4 2x8 DDR4 3000MHz
SSD: Samsung 860 QVO 1TB
PSU: EVGA 500W
OS: Windows 10

Check temps under synthetic load
Check HDD SMART status
Remove any overclocks
Hard reset UEFI
Manually set platform clock to 100 MHz
Disable PBO (Precision Boost Overdrive)
Disable XMP

Thanks for responding!

Temps have always been good, the machine is just for web browsing too so never sees much load.
Checked SSD with Samsung Magician and updated its firmware.
Never overclocked before.
Can try resetting UEFI tomorrow.
Not sure how to manually set clock?
Couldn't find PBO in bios and there's no setting for XMP but I followed a guide to set it I think.

In this case, you'll be setting "APU Frequency" I believe. You'll need to turn Ai Overclock Tuner to "Manual"

- I mentioned this, as some boards fiddle with it to slightly improve performance. Default per AMD CPU Specification is 100 MHz.

PBO is likely revealed when the Ai Overclock Tuner is set to "Manual". It's typically with other CPU specific settings, such as IOMMU, and sleep states.
