Hi everyone, I’m running into a bizarre performance issue that started after I swapped my SSD and did a fresh Windows 11 reset. I’m hoping someone can help me figure out what’s bottlenecking my system before I have to take it to a Microcenter.

Originally, I was having mouse stuttering and my old Samsung 970 SSD was running at 1/3 of its rated speed. I replaced it with a Samsung 990 Pro 1TB and did a full Windows reset. The mouse lag is fixed, but now the entire system is performing significantly worse than it did before.

The Issue:

• NovaBench Results: CPU score is 3010; GPU score is 275 (both performing way below typical ranges).
• Gaming: Barely hitting 80 FPS in Marvel Rivals Stress Test
• System Stutter: If I run any other app (like YouTube) while a game is open, it freezes or stutters to the point of needing a restart.
• Drivers: I’ve downloaded and reinstalled all previous drivers.

System Specs:

• CPU: AMD Ryzen 9 7900X3D (Raphael 5nm)
• Motherboard: MSI B650 GAMING PLUS WIFI (AM5)
• RAM: 64.0GB Dual-Channel DDR5 @ 2400MHz (40-40-40-77)
• GPU: MSI NVIDIA GeForce RTX 3060 (Speccy is reporting 4095MB VRAM)
• Storage (OS): 1TB Samsung SSD 990 PRO
• Storage (SATA): 1TB Samsung SSD 870 QVO
• OS: Windows 11 Pro 64-bit
• Displays: 3-monitor setup

Current Red Flags I'm Looking At:

1. My RAM is showing as 2400MHz (4800MT/s), which seems very low for DDR5 on a Ryzen 7000 chip.
2. The GPU score of 275 is essentially "integrated graphics" level performance.

Any advice is appreciated!
