Still running Windows 8.1 or 7?  It’s time to upgrade to 10 or 11!

While you could continue to use your PC running an older version of Windows
Without continued software and security updates, it will be at greater risk for viruses and malware. Going forward, the best way for you to stay secure is on Windows 10 or 11. And the best way to experience Windows 10 or 11 is on a new PC. While it is possible to install Windows 10 on your older device, it is not recommended.

 Windows 2012R2 Server OS also expired, contact us to discuss upgrading your servers

Dean, Sue & Ted were incredibly knowledgeable about my two computer issues, guiding me every step of the way. From the initial diagnosis (evidently some computers have coolant to keep them cool, who knew?) to ordering the part to fixing the issue and even upgrading it, they communicated every step of the way. Very friendly staff with the expertise to fix your computer issues. They even helped me with a laptop battery that needed to be replaced. Very happy with their service and highly recommend them for all your computer needs.

Great people who know what they’re talking about. I took my pc to Best Buy 3 times in 2 months for the same problem. Best Buy couldn’t figure out. PC Systems had it figured out and fixed in less than a day. I’ll never go to the Geek Squad again. I highly recommend PC Systems. Just the nicest people who treat your problem like it was their own. Thank you so much!
