Plan your service · Garland
Bring the history along with the hardware.
If drivers, memory, a graphics card or the power supply have already been changed, that history helps the next assessment. Note what improved, what stayed the same and which original parts are still available instead of repeating unsuccessful fixes.
- List both the original and replacement component models, with dates or the order in which changes were made.
- Save the exact error message or a photo of motherboard status lights without including private account information or credentials.
- Confirm the Dallas or Irving intake choice before traveling, especially if you want a particular accessory tested with the tower.
Important files on the PC? Mention them before resets or reinstalls. Review data recovery options.

Gaming PC service questions
Should I bring a previously replaced graphics card with my Garland gaming PC?
Mention the previous card and why it was replaced when arranging intake. The technician can confirm whether that part is useful for the assessment. A repeated symptom with a different GPU is relevant, but does not identify the failed component by itself.
Where can Garland customers bring a gaming PC?
