I am very grateful that I found this business near my home. It is so hard these days to find a company that cares about customer service and CompuWiz does If you have any computer needs, I highly recommend it. My laptop was repaired in one day and the communication was excellent! I am definitely letting my family and friends know about this business. Thank you Chris at CompuWiz!

Took my PC in for a diagnostic and Chris was able to figure it out so quickly! Turns out my SSD had died, but he had it replaced in just a day. Wonderful service, I’m very grateful.

Fair price and very Knowledgeable. He fixed our laptop pretty fast. Changed hardware and made it so much better, without compromising any of our files.

I suspected my motherboard failed and brought it in, regretfully my suspicions were confirmed but it was replaced and repaired quickly even though it was the holiday season. If I or my husband need any repairs or upgrades in the future I know exactly where to take our PCs. Absolutely wonderful experience all around.

Chris was very helpful in the process of helping me repair my damaged screen on my Mac. On top of that he gave me a great price in comparison to apples. He was very professional and was able to complete the fix in two days. Would highly recommend!!!
