Plan your service · Addison
Decide what needs to travel with the tower.
A gaming desktop may work differently with another display or cable. Before traveling from Addison, explain whether the problem occurs before Windows, during a game or only with an accessory attached. We can then confirm which equipment is useful for intake.
- Record the monitor model, connection type and whether the PC shows its startup screen before the picture disappears.
- Ask the receiving branch whether to bring a specific cable, adapter or peripheral instead of packing the entire desk.
- For an onsite assessment, include apartment or suite access and keep the usual setup available for the agreed checks.
Important files on the PC? Mention them before resets or reinstalls. Review data recovery options.
