I'm looking for a friendly technician to give my desktop PC a thorough clean and organize my files. The computer is a mid‑range Windows PC, and I’d like a dust-free internal clean, cable management tips, and a tidy, well-labeled file structure. Preferences: back up important documents before any major changes, avoid deleting personal data, and install a couple of lightweight cleanup tools if appropriate. I’m hoping to schedule a session on a weekday morning, and I’d appreciate clear explanations of any recommendations you make. The goal is better performance and easier file access without risking data loss.
