Internet, Keyboard, and Mouse all keep disconnecting briefly - Windows 10

edited December 2022 in General Discussion

Every now and then my Internet (Ethernet), Keyboard, and Mouse - or some subset of these - lose connection for maybe 10 seconds. The internet one happens especially when gaming. This happens multiple times a day and sometimes my whole PC just randomly restarts. I have tried getting off Ethernet and it did not help. I also opened up my PC and cleaned and secured everything. All my drivers are also up to date. I have:

CPU: AMD Ryzen 7 3700X 3.6 GHz 8-Core Processor

Motherboard: Asus ROG STRIX B450-F GAMING ATX AM4 Motherboard

Memory: Corsair Vengeance LPX 16 GB (2 x 8 GB) DDR4-3200 CL16 Memory 

Video Card: MSI GeForce RTX 2080 SUPER 8 GB GAMING X TRIO Video Card

Power Supply: Corsair RM (2019) 750 W 80+ Gold Certified Fully Modular ATX Power Supply

One time after my PC reset I went into my logs and found this:

A fatal hardware error has occurred.

Reported by component: Processor Core

Error Source: Machine Check Exception

Error Type: Hierarchy Error

Processor APIC ID: 1

I have had no issues until the past few days. My PC temperature is fine. My PC is about 2 years old.

    It is possible that you have a CPU or Motherboard issue. One or both might need to be replaced. I recommend bringing your computer into your closest Micro Center and drop it off for diagnosis. That is the only way we can know for sure.

    First thing I'd test for her is a power saving feature creating issues. Try setting yourself to the high performance power plan. Also, what BIOS version are you on with that board?
