Audio & Sound Output

Audio crackling or popping in games Audio cutting out intermittently Headset microphone not detected Headset sound only in one ear No audio output from any device Onboard audio not detected in system Surround sound channels mapped incorrectly USB audio interface disconnecting during use Wrong audio device selected after every reboot Volume level extremely low even at maximum

Cooling & Thermals

Case fans not spinning under load CPU temperatures spiking quickly in games GPU temperatures reaching unsafe levels Liquid cooler pump suspected not running Liquid cooler making grinding or rattling noise System shutting down due to overheating Thermal throttling causing frame drops Unbalanced fan curve causing loud ramping Very high idle temperatures on CPU or GPU Visible dust buildup blocking heatsinks or filters

CPU & Motherboard

BIOS not retaining settings after shutdown CPU reported at incorrect speed or core count Debug LEDs on motherboard indicating fault Frequent blue screens under heavy CPU load Front panel headers not working correctly PCIe slots not detecting installed cards Random freezes requiring hard power off System not posting or no BIOS screen XMP or memory overclock profiles unstable Some RAM slots not detecting modules

GPU & Graphics Output

Artifacts or visual glitches during gameplay Black screen when launching games Display output only from motherboard graphics Driver crashes or resets during gaming GPU not detected in operating system Low frame rates compared to expected performance Multiple monitor setup not working correctly Screen flickering or signal loss under load System crashing only when GPU is stressed Wrong resolution or refresh rate options available

Networking & Online Connectivity

Ethernet port not detecting cable connection Frequent disconnects from online game servers High ping or latency only on this desktop LAN or local multiplayer not working correctly Network speed much lower than expected on this PC No internet connection despite working router Port forwarding or NAT issues affecting games Voice chat not working in online games WiFi adapter not detected or unstable Wired connection dropping under heavy traffic

Peripherals & Input Devices

Controller disconnecting or lagging during play Gaming mouse buttons not registering correctly Gaming mouse not detected on some USB ports Keyboard keys intermittently not responding Keyboard RGB lighting not working as expected USB hubs or extensions causing disconnects USB ports on case not detecting devices VR headset not detected or unstable in games Wireless peripherals dropping connection frequently Wrong input device selected in some games

Power Supply & Power Delivery

Cables not reaching components without strain Frequent restarts when system under heavy load Loose or unstable power connectors to GPU or CPU Power supply fan not spinning when system on Power supply making buzzing or electrical noise System not powering on at all from power button System powers on briefly then shuts off System unstable after installing new GPU Suspected insufficient wattage for installed hardware Unexpected power loss only during gaming sessions

Software, OS & Game Environment

Anti-cheat blocking games from starting Background processes causing stutter in games Frequent crashes to desktop across multiple games Game launchers not opening or updating Game settings not saving between sessions Operating system very slow to boot or shut down System restore or recovery options not working Windows activation or licensing issues Drivers failing to install or update correctly Frequent error messages during normal desktop use

Storage (SSD / HDD / NVMe)

Boot drive not detected by BIOS or OS Files or folders disappearing unexpectedly Frequent disk or read/write error messages Game installs failing or becoming corrupted NVMe drive overheating or throttling in use Secondary drives not appearing in operating system System hangs or freezes during disk access Very slow load times in games or applications Drive capacity reported incorrectly by system Clicking or unusual noises from mechanical drive

Tower Case, Cabling & Physical Build

Cable management causing strain on connectors Case damage, dents or bent frame Cables obstructing fans or airflow paths Front panel ports not working correctly Loose screws or components inside the case PCIe brackets or slots misaligned with case Power button on case not responding Reset button on case not functioning Severe dust buildup throughout the system Side panel not fitting or closing correctly
