Why Was There Buzzing and Mouse Lag?
A customer reported two problems with their PC: a buzzing sound whenever they played games, and a mouse that lagged during use. On their own, each symptom could point to several possible causes. Together, they pointed toward the front I/O area and motherboard connection path.
The front I/O is the row of ports on the front of a PC case, including USB connections, a headphone jack, and a microphone input. It connects to the motherboard through internal cables. When there is an issue in this area, USB devices can behave erratically, and the front audio connection can pick up electrical interference from components under load.
Root Cause
The symptoms were traced to the front I/O area and the MSI B650M Gaming Wifi motherboard. The front USB connection was linked to the mouse lag, while the front audio path was linked to buzzing during gaming. Both the front I/O components and MSI B650M Gaming Wifi motherboard were replaced, then the system was tested again after the repair.
What We Checked First
- Mouse on front USB versus rear USB: helped narrow down the laggy mouse symptom
- Front audio jack: buzzing was present during gaming and pointed to the front audio path
- Front I/O cable connections to the motherboard header
- MSI B650M Gaming Wifi motherboard condition: replacement required
- GPU, RAM, and storage: checked during diagnosis
How We Fixed It
- Front I/O checked: The mouse and audio symptoms were tested around the front USB and front audio ports. This helped narrow the issue to the front I/O area and motherboard connection path.
- Motherboard inspected: While checking the front I/O symptoms, the MSI B650M Gaming Wifi motherboard was found to require replacement.
- Front I/O and motherboard replaced: The front I/O components and MSI B650M Gaming Wifi motherboard were replaced during the onsite repair.
- System tested: After the repair, the PC was tested again. The audio was clean, the mouse was responsive, and the buzzing was no longer present after testing.

Frequently Asked Questions
Why is my PC making a buzzing sound when I play games?
Buzzing during gaming can often come from the front audio circuit picking up electrical interference from components under load. Test it by plugging your headphones into the rear audio jack on the back of the PC. If the buzzing stops, the front I/O path is worth checking. If it continues, the issue may be with the audio device, drivers, cable, speakers, or another component.
Why is my mouse laggy on front USB ports but fine on rear USB?
Front USB ports connect to the motherboard through an internal header and cable. If the front I/O area, cable connection, or motherboard header has an issue, USB devices plugged into the front can behave erratically. Moving your mouse to a rear USB port bypasses the front I/O path and helps narrow down the cause.
