I just put together my new gaming PC yesterday and I'm running into some issues related to DPC spikes and frequent page faults. Here are my specs: GIGABYTE B850 AORUS ELITE WIFI7 motherboard, a Ryzen 9 9850X3D processor, an MSI 5080 Gaming Shadow 3x OC GPU, and 64GB of DDR5 RAM at 6000MHz CL30 from G.Skill. I'm also using a 2TB Samsung EVO 990 SSD and a 850W RMX power supply.
I've enabled the AMD Expo profile in the BIOS and switched the High Bandwidth Support on and off, but the results have been the same. Currently, my BIOS settings are as follows: CPPC Dynamic Preferred Cores OFF, SMT OFF, X3D Turbo Boost OFF, Re-Bar Support ON, 4G Decoding ON, Spread Spectrum Control OFF, and Precision Boost Overdrive enabled, with Global C-State Control OFF.
I scored 8400 (400 below average) in Steel Nomad and 10142 (around average) on a CPU test from 3D Mark. However, when I play Valorant, the frame drops start occurring after just a couple of minutes. I've checked my system temperatures with HWINFO and everything seems fine, with no throttling observed.
I also ran a LatencyMon check while testing, and it indicated that the system is generally suitable for real-time tasks. Just to note, I've experienced around 1405 hard page faults, with the most being attributed to the task manager. Can anyone help me troubleshoot this?

First off, make sure your BIOS and chipset drivers are up to date. If everything is running the latest versions, you might want to check if the issues occur only when playing Valorant. Sometimes it can be the game itself or network issues causing lag and frame drops.
If it's mostly happening in Valorant, have you thoroughly checked your network? You might not be losing packets, but check your ping and do a speed test to confirm everything's fine on that front. Lag can totally mess with gameplay!
I have fiber at 2 gigs which should be solid, so I don't think it's that. Maybe a fresh install of Windows could help. I'll try that next.
It might be worth trying a different GPU driver version, as sometimes updates can introduce issues rather than fixing them. Roll back or test an older version to see if that resolves the problem.

I just checked, and my BIOS is on F10, so I'm good there. For chipset drivers, I installed them from my motherboard's website and they are up to date. Still, I suspect the network could be a factor.
