The problem seems sporadic but often occurs while compiling shaders in new games. Troubleshooting Steps: Updated BIOS with various stable firmware. All chipset, GPU, Realtek sound & network drivers were reinstalled. Disabled IGPU, WiFi & Bluetooth. Tested default settings (no EXPO, no PBO). Applied Windows optimization tweaks and checked AESEGA USB suggestions from forums. Software Used: latencymon, CPU-Z, GPU-Z, benchmarks... I made some changes, but the issue still happens randomly, though less often now. Here are a few latencymon results (consistent values Wdf01000 or dxgkrnl). Will changing the GPU resolve it? _________________________________________________________________________________________________________ CONCLUSION Your system struggles with real-time audio and other tasks. You likely experience buffer underruns—drops, clicks, or pops. Multiple DPC routines may run too long. Possible causes include power management issues; disable CPU throttling in Control Panel and BIOS. Verify BIOS updates. LatencyMon has been analyzing your system for 0:12:55 on all processors. _________________________________________________________________________________________________________ SYSTEM INFO Computer name: MELIO OS version: Windows 11, 10.0, version 2009, build: 26100 (x64) Hardware: MS-7E26, Micro-Star International Co., Ltd.

Interrupt handling appears inefficient, likely causing buffer issues. Consider updating BIOS, checking drivers, and reviewing power settings. LatencyMon data supports these findings. _________________________________________________________________________________________________________
Check for power-related problems and update your BIOS. Turn off C-states, disable global C-state control and CPPC in BIOS settings, and adjust power plans in Windows. Disable USB selective suspend and reinstall chipset drivers if needed. Consider downloading directly from AMD instead of MSI. Look for WHEA or device reset events in Event Viewer. If issues continue, test with a different PSU or motherboard to pinpoint the cause. Those B series boards have experienced some USB/VRM problems.
When you buy boards, the price reflects what you receive. If you were in your position, check local sales. A solid deal lets you upgrade to a better model at a reasonable cost. I favor Asus mobos, but MSI and others perform just as well. You get value based on what you pay for. Consider picking up a more expensive board if you find a good offer elsewhere. If you share your country, I can help locate some affordable sales. These are decent budget options. But if you spot a better deal—like a budget X series board—opt for it.
I currently own the MSI B650-S Wi-Fi but feel let down. I usually choose Gigabyte products and haven’t experienced this issue before. Amazon prices are high in Morocco, yet locally I can pick from these options: Gigabyte B650 GAMING X AX V2, 220$, Gigabyte B650 EAGLE AX, 190$, Gigabyte B650 AORUS ELITE AX V2, 240$, Gigabyte B650 UD AX, 180$. Updated: After the problem started, I checked the drivers and noticed the issue disappeared when I turned off the PCIe root port. I should investigate further.
