tldr: FPS intermittently dropping to zero in online games. Drop lasts from less than a second to a few seconds. Happens every 5-10 minutes give or take. Possible random stuttering in normal use (freezing while typing in forum). Root cause still undetermined.
System Specs:
CPU: Ryzen 9 5900X
GPU: EVGA Nvidia RTX 3070 Ti
Motherboard: MSI X570 Gaming Plus
RAM: Corsair Vengeance Pro 3600 18-22-22-42 2x16GB (plus the 2x16GB recently bought)
SSD: Intel 670P
PSU: Corsair RM750X
Preceding all of this:
Sunday: Installed some new RAM (2x16GB - same model as original 2x16GB). Ran Memtest. RAM failed hammer test; also had difficulty booting at 3600 (Motherboard loaded it at 2133mhz). Removed new RAM and ran computer.
Rebooted: Windows said it installed some updates (probably hadn't rebooted in a month or so).
Monday: First instance of the 0 FPS drop. Happened at least once during 1 game. Thought it might be server fluke.
Tuesday: Multiple instances of FPS drop. Began investigating.
Wednesday: Thought there might be an issue with my old RAM (perhaps it was loose after installing new RAM). Moved old RAM from slots 2/4 to 1/3. Same issue. Tried slower RAM from old PC (wouldn't boot... might have been a BIOS thing as XMP was still enabled and this RAM was much slower. No luck. Ran MEMTEST on old RAM. No failures.
Tried swapping out old RAM and put new RAM in 2/4 (testing seating issue hypothesis). Ran MEMTEST 8 passes no failure.
Thursday: Tried running with with new RAM in 2/4 after MEMTEST passed. Still issue.
Stuff I've checked/tried.
At this point I'm thinking of swapping Video Card (I have an old GTX 1070 I can run) and swapping PSU to see if either of those makes a difference but I hate rerunning PSU wires.
I'm still suspicious of the RAM at this point but given I've tried both pairs separately and tried the different slots, I'm not convinced it's the issue either. Especially since the old RAM was perfectly stable. Has there ever been an instance of old RAM becoming corrupted by new RAM (RAM STDs?)

Stuff I've checked/tried.
- Checked temps of CPU/GPU. No troubling spikes.
- Ran Prime95 to test stability. No issues.
- Ran Furmark to test GPU stability. No issues (no drop to 0 FPS either... can't seem to reproduce in synthetic tests).
- Ran 3DMark benchmark and stress test. Benchmark results were consistent with my original benchmark results from when I built the PC a year ago. Stress test score had 98.7% frame rate stability. No drops to 0.
- Rolled back Windows installation. Did not fix.
- Ran DDU. Updated Nvidia drivers. Did not fix.
- Ran sfc /scannow. Said it found corrupted files but did not fix the issue.
- Checked PSU cables. Appear to be attached.
- Check Task Manager during drops. The only processes I see (briefly spike) were "Service Host: Local Service (Network Restricted)" and "Service Host: State Repository Service". If I wasn't paying close attention, I wouldn't even have been able to notice that they spiked so I'm guessing it's not the issue.
- Will add more that I have forgotten later....
- Tested in Single player game. Framerate would randomly drop from 180-200 to 30 fps. All in same area of game.
- I also pinged google.com during the drops during online game session. No ping spikes.
- In game ping monitor was consistent during the fps drop.
- Updated BIOS from 7C37vAH to 7C37vAI.
- Put GTX 1070 in. Same issue.
- Reset CMOS.
- Checked CPU pins and reinstalled.
- Tested a different PSU.
- Manually set timings on RAM. Can get 4x16GB to boot. Still intermittent FPS drops.
- Both SSD/HDD are showing good on SMART and getting reasonable speeds.
At this point I'm thinking of swapping Video Card (I have an old GTX 1070 I can run) and swapping PSU to see if either of those makes a difference but I hate rerunning PSU wires.
