My Windows PC stutters constantly, regardless of whether it's during startup, while running programs, or even while playing games. This issue started after I recently installed new hardware.

I'm looking for an experienced technician who can diagnose and fix this problem. The ideal freelancer should have:

- Knowledge of system performance optimization
- Ability to work with various hardware components

Please include in your bid any relevant experience you have and an estimated timeline for completion.
