Plan your service · Glenn Heights
Help us reproduce an intermittent failure.
A PC may start normally and still restart, freeze or lose video during ordinary use. Note the application, time until failure and what remains responsive. That record helps the technician compare controlled checks with the behavior you experience without assuming one stress test proves stability.
- Write down the game or application, approximate time until failure and whether the PC restarts, stays frozen or loses only video.
- Describe any pattern after sleep, a cold start or a long session without repeatedly forcing the computer through an unsafe failure.
- Arrange intake with someone who can explain the issue and approve work; keep game credentials and recovery keys out of messages.
Important files on the PC? Mention them before resets or reinstalls. Review data recovery options.

Can you check a Glenn Heights PC that passes a stress test but still crashes in games?
Yes. Report the exact game, error and behavior. A successful individual test does not rule out every driver, power, memory, storage or application-related issue. Mashfix reviews the symptoms and selects relevant checks; intermittent faults may require extended workshop observation.
