Performance declines and system failures occur after launching the new PC.
Performance declines and system failures occur after launching the new PC.
Hey everyone! I recently assembled a new PC a few days back (MSI Z790 Tomahawk Wifi, I9 13900K, Asus RTX 4070Ti Strix OC, 2x16GB Corsair DDR5 6400MHz CL32, 1xSSD Samsung 990 Pro, 2xSSD Samsung 970 Evo from my previous machine all functioning well). I installed Windows 11 Pro on one of them.
Before diving into Jedi Survivor on a 9900K + 3080TI with no problems at all—not even a single crash—I experienced frequent FPS drops and crashes after using this build. I’ve kept an eye on temperatures during gameplay, which stayed low (45-50°C on CPU, 60°C on GPU).
Here’s what I noticed:
a) Initially, everything runs smoothly for 1-2 hours. After a while, FPS starts to dip. Monitoring the GPU during these drops shows power consumption dropping from around 200+W to under 80W, then slowly rising again as FPS recovers.
b) Alt-tab increases the likelihood of FPS drops.
c) Sharing my screen on Discord causes quick crashes and FPS issues if I press alt-tab. This suggests a GPU driver problem, possibly linked to Nvidia Broadcast. Restarting Discord seems to fix it temporarily.
d) After switching back in via alt-tab, FPS starts low and gradually improves (about 3-4 seconds to normal). It worked similarly for Star Wars Jedi Survivor and Far Cry 6.
Before crashes, FPS would drop to 10-15 for a few seconds before the game quits. I’ve stress-tested with multiple tools—no crashes detected. I checked RAM with and without XMP, tried different frequencies, even used PCIE version 3 in BIOS. The GPU is mounted vertically with a PCIE 4.0 from Lian Li, and I haven’t seen any blue/black screens except for game crashes.
At first, I suspected RAM issues because after installing everything (without performance tweaks), I got multiple blue screens. So I replaced two sticks, but they still caused crashes. BIOS is set to default, XMP enabled, DRAM Voltage 1.4V.
I’m frustrated since my old PC was more reliable. What should I do next?

This idea popped into my mind after reading a few lines, but as I went deeper it felt less relevant. It might offer a tiny clue. I suspect memory might be the issue. Last weekend I tried turning on 'memory context restore,' but games kept crashing. After switching back, everything functioned normally. (MCR appears to skip the usual memory setup changes that happen after each AM5 post...this is our first difference, since this pattern may not apply to Intel CPUs or XMP settings at startup.) Do you have a similar memory-related setting for Intel or XMP? Could turning it off and doing a full memory calibration on boot help? I’m not sure, but it seems like something simple to try. [The CTDs I’ve used on this machine are a bit unusual—most issues seem tied to memory; whether context restore works or needing a large page file is what matters most. I’ve experienced sudden program freezes, unresponsive apps, and crashes that vanish without clear signs of running processes. These memory problems usually happen abruptly.]
Hey, I spotted the problem. The Windows 11 version is messed up—I only checked it after installing Windows 10 and everything functioned properly.
