Question Can someone help me figure out why my PC malfunctions while gaming?

Jan 7, 2023
Here’s a little background before I list out what I’ve done so far followed by my system specs. Sorry it’s wordy but I want to capture as much info as possible. I’ve been a long time lurker so I appreciate any advice!

Background: I built my a PC about a year ago (didn’t tune components much) and the last several months I’ve been having issues with USB peripherals disconnecting or the whole system freezing and crashing while I play games like Overwatch, FIFA, Dota, etc. Sometimes the game will freeze completely and I’ll have to do a hard reboot, but at the very least either of my mouse and keyboard will disconnect within 5-10 minutes of playing (even in menus), and only restarting my computer will fix this. Doesn’t happen any other time of regular PC use, just when playing a game. It’s odd to me because I use a USB wifi adapter which I plug into the motherboard and never have issues with it disconnecting. I should also note that when the PC fully crashes the disk utilization climbs to 100% and the CPU will get into the mid-90s C, so I’m speculating it may be something with the mobo or CPU, or maybe the power supply is getting too stressed. However, I believe AMD has said it’s normal for the 5600 to run in the mid 90s so I don’t know if CPU cooling is really an issue. Also the display ports from the monitors are plugged into the GPU.

Of the many things I’ve tried, I updated the chipset driver and my games ran fine for about a month before going back to the same problem a couple weeks ago. I am not sure what to do at this point other than spending hundreds of dollars on replacement parts. Below are all the things I’ve tried so far mostly in chronological order:
  • Checked drivers for peripherals
  • Plugged mouse and keyboard into designated ports in mobo and in other USB ports in mobo and front of pc case
  • Updated chipset driver from mobo’s website
  • Updated BIOS to latest version
  • Replaced SATA 2.5 SSD with NVMe PCIe 4.0 M.2 SSD
  • Reapplied thermal paste to CPU and rerouted cables for better airflow in the case
  • Fresh windows 10 install
  • Activated windows (got a key from a friend, had been using an inactivated version) and got a bunch of new updates including some from AMD
  • Ran stress tests on my GPU (FurMark - FHD test) and CPU (Prime95) and both seemed to perform fine. GPU never really went past 70-75C; ran the CPU test for well over 5 minutes and it starting getting too hot for my liking (95-98C) so I force stopped the test.
  • Updated GPU driver
  • Replaced old Logitech G500 mouse with G502 Hero
After all of these things, I still have the same problem. I really appreciate any and all help! Hoping it’s just something obvious I’m missing but who knows. There are some things I wanted to try next, but I don’t know what to do beyond this:
  • Test a different mobo, power supply, and/or RAM sticks. Replace as needed
  • Move RAM sticks from A2/B2 slots to A1/B1 slots
  • Improve CPU cooling
  • Tune voltage settings for CPU and/or GPU
  • Tune fans for CPU and/or GPU
PC Specs:
  • Motherboard: ASRock B550m Pro4 AMD AM4 microATX
  • CPU: Ryzen 5 5600x (w stock cooler)
  • GPU: Asus Dual Nvidia RTX 3060
  • RAM: Crucial Ballistix 16GB (2x 8GB) DDR4-3000
  • SSD: WD_Black SN770 1GB Gen4 NVMe
  • Power Supply: EVGA Bronze 650W BQ
  • Mouse: Logitech G502 Hero
  • Keyboard: Razer Blackwidow V3
  • Case: Lian Li Lancool 170M MatX
Thank you!

Welcome to the forums, newcomer!

Updated BIOS to latest version
For the sake of relevance, please state the BIOS version.

Move RAM sticks from A2/B2 slots to A1/B1 slots
Revert to slots A2 and B2.

Fresh windows 10 install
Where did you source the installer for the OS?

Power Supply: EVGA Bronze 650W BQ
How old is the PSU in your build?

disk utilization climbs to 100% and the CPU will get into the mid-90s C
Seems to me like it's memoryleak, that's an issue with your OS(essentially a corrupt OS)...the solution to that is a reinstall of your OS after recreating your bootable USB installer to rule out a corrupt installer.

How many fans are in the case and how are the fans oriented in your chassis?
