I'm looking for a qualified technician to clean my computer and optimize its performance. It’s a mid-range desktop running Windows 10, with slow startup and some fan noise. I’d like a thorough physical cleaning, dust removal from inside the case, fans, and vents, plus software cleanup: uninstall unused programs, remove bloatware, run malware/virus scan, clean temporary files, and optimize startup programs. Please advise on hardware checks if needed and provide tips to maintain performance. I prefer a session around mid-morning and can accommodate a 2–4 hour visit depending on the scope. If you identify hardware cooling issues or need parts, I’m open to recommendations.
