Hi, I’m looking for help to clean my desktop computer and improve its performance. The unit is a mid-2019 tower with standard air cooling, and I’d like a thorough internal and external cleaning, including dust removal from fans, heatsinks, and vents. Please check thermal paste if necessary and advise on improving airflow. I’d prefer a careful, seated-at-desk service, using anti-static precautions and environmental cleaning products. If possible, please provide a brief report on any upgrades or maintenance tips for future care. Irish address, local time availability appreciated.
