performance decrease PC Freezing and Stuttering

PC Diagnoses:

 

Parts:

• PSU: RM750x (Corsair)
• Motherboard: MAG B550 TOMAHAWK (MSI)
• CPU: Ryzen 9 5900x (AMD)
• GPU: Nvidia GeForce RTX 3080 Gaming X Trio 10G (MSI)
• RAM: 32GB Dual-Channel DDR4 @1600MHz (16-18-18-38) Trident Z Neo (G.Skill)

Summary of Complaints:

What I am currently experiencing: the programs utilization usage for the GPU spike from 1%-2% all the way up to 30%-40% just in a matter of seconds. My PC Freezes, I can hardly even move my mouse. -This happens even in the BIOS. The Realtek Lan Port drops connection about every 5 minutes for a duration of 0.25 - 1 seconds. My Audio interface hardly even Works. (It is a Zoom H6 plugged in via USB).

 

From what HWinfo is telling me, the Voltage changes are INSANE, the power draw is NOT consistent.

 

I just want to make sure that I am headed into the right direction while testing these parts and updating firmware, drivers, and software correctly. Any insight is much appreciated.

 

What’s in Good Condition:

 

• CPU (Cinebench: Consistent Single-Core and Multi-Core Performance under load)
• GPU (Tried Another Nvidia GPU and it had the same issue + 3DMark Score for the 3080 was Great)
• SSD - Boot Drive (No Errors: Verified from CHKDSK /R)
• RAM (No Errors: Verified from MemTest86 + Windows Memory Diagnostic Tool)
• Surge Protector + Power Outlet (No Errors)
• Thermals (Under 60 °C for the CPU, GPU and RAM while under load)

 

Things I did:

• Updated motherboard BIOS to be to support the CPU
• Reinstalled Windows 10 Pro 3 times from a USB. (A FULL reset, removing ALL files).
• Enabled Gameboost for the CPU in the BIOS
• Enabled XMP for the RAM in the BIOS.
• Used DDU to refresh GPU.
• Updated VBIOS from MSI Dragon Center
• Updated CPU Drivers (from AMD)
• Updated GPU Drivers (Game Ready Driver from Nvidia Geforce Experience)
• Enabled Resizable BAR for GPU

 

Things I DIDN’T do:

• Manually Overclock CPU or GPU

 

 

Potential Problems:

• PSU
• Motherboard

Nvidia was thinking the same thing with changing slots.
