Cantrell's Computer Sales & Service: Serving Central Contra Costa County

From new and refurbished computers to system maintenance, upgrades and support, we provide the computing needs of our customers throughout central Contra Costa County. We can help find the most suitable solution when you want help with:
  • Data recovery and backup
  • Upgrading your slow and aging computing equipment
  • Data transfer from original to new computers and/or laptops
  • Data Backup

Few things in life are more agonizing than finding out your data is corrupted or overwritten and you have no backup. Backup systems can be as simple or as sophisticated as the need requires. Let Cantrell’s suggest the best, most cost-effective solution for your operation.

  • Equipment, New & Refurbished
We source and build systems to suit your needs and budget. We understand the last thing you can afford is to waste money. Doing a needs assessment and making recommendations for new vs refurbished equipment before you make a purchase is your best investment of time. Ask about our “Test Drive” and rental options!
  • Security
Concerned about a computer virus? Ransomware? We can remove viruses, trojans, root kits, and spyware while leaving your precious data and applications intact. If the malware has damaged the operating system beyond repair, we’ll make the process of a full-system reload as painless as possible. Get more peace of mind by having the Cantrell team assess any threats.
  • In-Shop Service
Whether your computer is new or old, occasionally your equipment will give you trouble. Before you toss your existing PC, notebook, or Mac, let us diagnosis the issue. We’ll help you determine the least expensive option: repair, upgrade, refurbish, or purchase new. Our award-winning repair shop frequently saves customers money by repairing computing equipment and extending its useful life.
  • On-Site & Remote Services
Cantrell’s offers both on-site and remote services at your home office to save you time, hassle, and business interruption. Our services are available by appointment. Our technicians are respectful and courteous and are available to discuss over the phone what service options you might need.
  • Upgrades
Is your computer running slower than you want? There are hardware upgrades that will improve the performance and extend the useful life of your computer. Installing more memory (RAM) and upgrading to a solid state drive (SSD) are popular options. Other options include a newer hard drive, faster video card, and faster CPU. Call us to set up an appointment! We will work with you to determine your upgrade options on your PC or Mac.
