Most common problems
The problems people bring us most often. Difficulty and time up front — every card starts with the fix that actually works.

When a fast PC suddenly crawls, it's almost always one of four things. Check them in this order.
Any · Maintenance
Fix a PC that overheats and fans like a jet engine
Loud fans usually mean dust, not a failing fan. A clean-out often fixes half of all 'my PC is slow' tickets.

Stop your PC from sleep-glitching your network
Ethernet that drops right after wake-from-sleep, or Wi-Fi that needs a manual reconnect — it's the NIC trying to save power

No sound? The four-minute fix
Most 'my PC has no audio' tickets are the wrong output device selected after a driver update or a plugged-in headset.
macOS · Mac
Speed up a sluggish MacBook

Win 10 / 11 · Gaming
Stop games stuttering — the 5-point checklist

Win 10 / 11 · Maintenance

'You're on mute' is usually a mute switch, Windows listening to the wrong input, or microphone access switched off for the app you're calling from. Windows' own microphone test tells you which in a minute.
