Hardware, networking, and technical support since 1985.
DT Computer Sales & Service is the technology arm of Diversified Technologies — helping homes and businesses keep systems fast, secure, and reliable from our Helena and Findlay shops.
From a slow laptop to a small-business network, our technicians handle repair, upgrades, and everyday IT support.
Is your device slower than usual, or did a risky click leave you uneasy? We can clean things up and get you safely back online.
Losing files can mean losing everything. With the right tools, we can often recover data from failing drives and damaged systems.
From operating systems to SSDs and other hardware, we can speed up everyday work and keep your setup current.
Ask about fitting Linux into a Windows network for file, web, FTP, email, and more — often with lower licensing cost and less downtime.
We build servers, host domains, troubleshoot help-desk issues, run service calls, and install custom ethernet cabling.
Both shops serve their communities with practical, on-time repairs — bring a device in or ask about an on-site visit.
Visit or contact the shop closest to you. Each location has its own site with additional local details.
