Compatibility, installation and stability after a change.
Plan your service · Cockrell Hill
Bring the symptom, not the whole desk by default.
A display fault may involve the monitor, cable or tower, while other failures can be tested with the PC alone. Describe what stays on when the screen goes black. The Dallas team can advise which accessories help reproduce the problem.
- Record whether the PC reaches its startup logo, loads Windows or loses the image only after a game begins.
- Note the monitor model and cable type, and ask which display equipment to bring before packing a large monitor.
- Include any motherboard warning lights or beep patterns in the request; a short description is enough without passwords or account details.
Important files on the PC? Mention them before resets or reinstalls. Review data recovery options.

Gaming PC service questions
Should I bring my monitor from Cockrell Hill with the gaming PC?
Ask Dallas before traveling. The monitor or its cable may help reproduce a display-specific issue, but not every repair needs them. Describe whether the screen reports no signal, whether another display works and whether the tower continues running.
